Infection control; Multidrug resistance; Stewardship Control de infección; Resistencia a múltiples fármacos; Administración Control d'infecció; Resistència a múltiples fàrmacs; Administració We explored the self-reported antibiotic stewardship (AS), and infection prevention and control (IPC) activities in intensive care units (ICUs) of different income settings. A cross-sectional study was conducted using an online questionnaire to collect data about IPC and AS measures in participating ICUs. The study participants were Infectious Diseases–International Research Initiative (IDI-IR) members, committed as per their institutional agreement form. We analyzed responses from 57 ICUs in 24 countries (Lower-middle income (LMI), n = 13; Upper-middle income (UMI), n = 33; High-income (HI), n = 11). This represented (~5%) of centers represented in the ID-IRI. Surveillance programs were implemented in (76.9%−90.9%) of ICUs with fewer contact precaution measures in LMI ones (p = 0.02); (LMI:69.2%, UMI:97%, HI:100%). Participation in regional antimicrobial resistance programs was more significantly applied in HI (p = 0.02) (LMI:38.4%,UMI:81.8%,HI:72.2%). AS programs are implemented in 77.2% of institutions with AS champions in 66.7%. Infectious diseases physicians and microbiologists are members of many AS teams (59%&50%) respectively. Unqualified healthcare professionals(42.1%), and deficient incentives(28.1%) are the main barriers to implementing AS. We underscore the existing differences in IPC and AS programs’ implementation, team composition, and faced barriers. Continuous collaboration and sharing best practices on APM is needed. The role of regional and international organizations should be encouraged. Global support for capacity building of healthcare practitioners is warranted.

Colorectal cancer is one of the most prevalent and deadly cancers worldwide. MicroRNAs are short single stranded non-coding RNAs that play important roles in carcinogenesis, tumor growth and tumor survival. Circulating microRNAs are increasingly becoming efficient and important biomarkers for several types of cancers. Herein, we aim to evaluate the diagnostic potentials of plasma microRNA-211 and microRNA-25 in colorectal cancer patients. Forty-four patients diagnosed with colorectal cancer and 40 healthy controls were recruited for the present study. Expressions of circulating microRNAs -211 and 25 were assessed by quantitative real-time polymerase chain reaction (RT-qPCR). Expression of transforming growth factor-beta, a key factor in tumorigenesis and a key inducer of epithelial to mesenchymal transition was assessed by enzyme-linked immunosorbent assay (ELISA) in patients' tissue and plasma. Our results demonstrated upregulated expressions of plasma microRNAs-211 and 25 correlated with the high transforming growth factor-beta (TGF-β1) expression in patients. In addition, plasma levels were positively correlated with lymph node metastasis. Moreover, receiver operating characteristic analysis demonstrated the reliability of microRNAs-211 and 25 for discriminating colorectal cancer patients from healthy individuals. MicroRNA-211 and microRNA-25 might have a tumorigenic role in colorectal cancer and their plasma levels could be potential biomarkers in its diagnosis.

BACKGROUND: Carpal tunnel syndrome (CTS) is the most prevalent entrapment neuropathy in the upper limb. The most consistent risk factors are female gender, age, and obesity. The results of previous studies are conflicting, and moreover, data from studies regarding obesity and nerve conduction velocity are not available for our Egyptian population. AIM: This study was designed to investigate the contribution of age and body anthropometry as predictor factors to the CTS and to identify patients at high risk for CTS among Egyptian obese women. METHODS: The study included 120 obese women grouped according to the clinical and electrodiagnostic (EDX) findings into two groups: 60 with CTS and 60 without CTS (non-CTS). EDX study was used in the diagnosis of median nerve entrapment at the level of the wrist, according to the American Association of Neuromuscular and EDX Medicine. Body weight and height were measured and then body mass index (BMI) was calculated. Waist-to-hip ratio (WHR) was determined from the measured waist circumference (WC) and hip circumference (HC). Mid upper arm circumference (MUAC) was measured as well. The receiver operating characteristic (ROC) curve was used to assess the power of age and body anthropometry as predictor factors for CTS. RESULTS: CTS obese cases showed significantly lower values of both median motor nerve conduction velocity (MMNCV) and median sensory nerve conduction velocity compared to those without CTS. Significantly higher median sensory latency and median motor latency have been found in CTS cases compared to non-CTS group. Significant differences in the mean age have been found between the two groups and a tendency for higher body anthropometry measures in the CTS cases relative to those without CTS. Moreover, there were negative correlations between MMNCV and obesity indices. Age showed the highest area under the ROC curve, followed by BMI, WHR WC, HC, and MUAC. CONCLUSION: Age and obesity indices are important risk factors that can be used as predictors to CTS in obese women. Age is a more powerful diagnostic tool relative to the anthropometric measurements. Women of age above 40 years and suffering from a high degree of obesity are at risk of developing CTS.

Two field experiments were conducted in a newly reclaimed land at a private farm in Village No 8, El-Minia Governorate, Egypt during two successive seasons (2017/2018) to evaluate the effect of integrated nitrogen fertilizer sources with organic and bio-fertilization on growth and yield components of the fennel plant. The experiment was arranged in a split- split-plot design. The organic treatments (0.0 and 5.0 t compost t/fed.) were arranged in main plots, nitrogen treatments (0.0, 10.0, 50.0 and 80.0 kg N/fed.) as urea or ammonium sulphate were allocated in subplots and bio-fertilizer treatments (without and with) were applied in sub-sub plots. The main effects of compost, nitrogen fertilization and bio-fertilizer showed that the maximum values of plant height, dry weight/plant, number of branches/plant, number of mumble/plant, number of umbellule's/umble and 1000-fruits weight were attained under 5 t/fed compost, 80 kg N/fed as ammonium sulphate with bio-fertilizer. The results of the interaction among treatments indicated that combined 5.0 t compost /fed with 50 kg N/fed as ammonium sulphate and using bio-fertilizer exhibited the highest values of growth and yield components of fennel. Meanwhile, we can save about 30 kg N/fed by treated fennel plants with organic and bio-fertilizers without any reduction in vegetative growth.

Colorectal cancer (CRC) is the second leading cause of cancer-related mortality in developing countries. Tripartite motif-59 (TRIM59) a member of the TRIM ubiquitin ligase family, is a surface molecule that regulates biological processes such as cell proliferation, apoptosis, and tumorigenesis. Previous studies reported that TRIM59 expression was upregulated in human CRC, however, the expression pattern and role of TRIM59 in benign colorectal lesions remain unclear. Sixty patients diagnosed with CRC and 60 patients with benign lesions (Crohn's disease, ulcerative colitis, adenoma, and familial adenomatous polyposis) were recruited to the present study. TRIM59 gene expression was assessed by real-time quantitative polymerase chain reaction. Expression of TRIM59 protein and p-AKT were determined using, enzyme-linked immunoassay while p53 expression was detected by immunohistochemistry. Antioxidant/oxidant role of glutathione (GSH)/malondialdehyde (MDA) were evaluated by colorimetric methods in all of the studied groups. Our results showed upregulated expressions of TRIM59 gene and protein levels in CRC tissues and benign colonic lesions compared to nontumor tissues. Their levels were higher in inflammatory compared to noninflammatory bowel lesions. There were significant interrelations among TRIM59 gene expression, protein levels, tumor, node, metastasis staging, and the presence of metastasis (p 0.0001). Receiver-operator characteristic curve analyses showed that at the cutoff point of 2.5 TRIM59 mRNA expression can discriminate between CRC cases and benign bowel group (area under the curve [AUC]: 0.639, sensitivity: 86.7%, specificity: 41.7%), and between CRC and controls (AUC: 0.962, sensitivity: 90%, specificity: 91.7%). TRIM59 could be a potential biomarker in the early detection, diagnosis, and treatment of benign colonic lesions and CRC.

This work is part of a larger research project studying the immune responses of a variety of plants. Once image-based (unpublished data) and another time, as in this study, biochemical parameters based. Plant models included three metabolically different plants, Vica faba L. (C3), Zea mays L. (C4), Mesembryanthemum L. (CAM). Pathogen models had Alternaria alternate and Pseudomonas syringe. All of which, along with the control treatment, represent nine plant-pathogen systems applied with three replicates of each studied species. To investigate the extent to which the immune response is transferred from infected leaves to uninfected leaves on the same plant, several physiological and biochemical immune responses were examined, including: two plant hormones, abscisic acid and Salicylic acid, and two active enzymes, Catalase enzyme and Peroxidase enzyme, two free radicals, ROS and H2O2. Results show that The studied hormones were significantly affected by the type of plant metabolism and the type of pathogen, sometimes by an increase and sometimes by a decrease in which ABA and SA increased in C3 and CAM plants when infected by Alternaria and varied when infected by pseudomonas syringe. At the same time, both ABA and SA decrease in C4 plants. The studied enzymes did not follow a specific pattern of increasing and decreasing response to a bacterial or fungal infection. Still, they differed significantly between plants of different metabolism according to the type of pathogen causing the infection. Infection of all three studied plants by Alternaria alternate and Pseudomonas syringae did not cause any significant changes at p≤ 0.05 in the free radical production of the leaves for both ROS and H2O2.

Lung cancer (LC) is one of the leading causes of cancer occurrence and mortality worldwide. Treatment of patients with advanced and metastatic LC presents a significant challenge, as malignant cells use different mechanisms to resist chemotherapy. Drug resistance (DR) is a complex process that occurs due to a variety of genetic and acquired factors. Identifying the mechanisms underlying DR in LC patients and possible therapeutic alternatives for more efficient therapy is a central goal of LC research. Advances in nanotechnology resulted in the development of targeted and multifunctional nanoscale drug constructs. The possible modulation of the components of nanomedicine, their surface functionalization, and the encapsulation of various active therapeutics provide promising tools to bypass crucial biological barriers. These attributes enhance the delivery of multiple therapeutic agents directly to the tumor microenvironment (TME), resulting in reversal of LC resistance to anticancer treatment. This review provides a broad framework for understanding the different molecular mechanisms of DR in lung cancer, presents novel nanomedicine therapeutics aimed at improving the efficacy of treatment of various forms of resistant LC; outlines current challenges in using nanotechnology for reversing DR; and discusses the future directions for the clinical application of nanomedicine in the management of LC resistance.

Structural Biology ,General Medicine ,Molecular Biology - Abstract
Breast cancer (BC) is prevalent worldwide and is a leading cause of death among women. However, cell-surface glucose-regulated protein 78 (cs-GRP78) is overexpressed in several types of cancer and during pathogen infections. This study examines two well-known BC drugs approved by the FDA as BC treatments to GRP78. The first type consists of inhibitors of cyclin-based kinases 4/6, including abemaciclib, palbociclib, ribociclib, and dinaciclib. In addition, tunicamycin, and doxorubicin, which are among the most effective anticancer drugs for early and late-stage BC, are tested against GRP78. As (−)-epiGallocatechin gallate inhibits GRP78, it is also being evaluated (used as positive control). Thus, using molecular dynamics simulation approaches, this study aims to examine the advantages of targeting GRP78, which represents a promising cancer therapy regime. In light of recent advances in computational drug response prediction models, this study aimed to examine the benefits of GRP78 targeting, which represents a promising cancer therapy regime, by utilizing combined molecular docking and molecular dynamics simulation approaches. The simulated protein (50 ns) was docked with the drugs, then a second round of dynamics simulation was performed for 100 ns. After that, the binding free energies were calculated from 30 to 100 ns for each complex during the simulation period. These findings demonstrate the efficacy of abemaciclib, ribociclib, and tunicamycin in binding to the nucleotide-binding domain of the GRP78, paving the way for elucidating the mode of interactions between these drugs and cancer (and other stressed) cells that overexpress GRP78.

Incorporation of organic amendments is one of the most eco-friendly and economic strategies for the restoration of contaminated soils through diminishing mobility and bioavailability of heavy metals in these soils. This study was carried out under field conditions during the summer season of 2017 on a clay loam soil naturally polluted with Cd (7.61 mg kg−1) due to successive irrigations with wastewater. The main goal of this study was to evaluate the influence of sugarcane bagasse-derived biochar (SBDB) at different rates on fractionation of Cd in soil and its implications on the growth of soybean and concentrations of Cd within the different plant parts. Incorporation of SBDB into the chosen contaminated soil caused noticeable changes in soil pH, electrical conductivity and organic matter, especially with increasing the rate of application. Immobilization of Cd in the used soil was highly influenced by soil properties. According to the sequential extraction procedure, application of SBDB had an efficient role in reducing the soluble/exchangeable fraction. Moreover, it declined both the reducible and oxidizable forms of Cd. The dry weight of soybean organs (roots, seeds, and straw) improved significantly with SBDB additions. The highest dry weight values of straw and seeds for soybean plants were recorded when the soil was treated with SBDB at rates of 15 and 30 t ha−1. Concentrations of Cd in straw and seeds of soybean were markedly affected by its availability in the soil. They decreased from 2.77, 0.96, and 0.62 mg kg−1 at the control treatment (CK) to 1.75, 0.47, and 0.20 mg kg−1 at B4 treatment (30 t SBDB) ha−1 in roots, straw, and seeds of soybean, respectively. In conclusion, the use of SBDB showed high efficiency in the amelioration of Cd-polluted soils and in decreasing Cd toxicity on soybean plants.

Extensive use of fertilizers and pesticides led to dangerous ecological effects and therefore the biological approaches have been widely recommended to prevent further deterioration for the environment. The current study was conducted to explore the potentiality of using single or combined inoculations by mycorrhizae, Bacillus subtilis and Pseudomonas fluorescence for controlling the infection of common bean plants with Sclerotium rolfsii on one hand and as bio-fertilizers for improving plants nutritional status on the other hand. The soil of study was mildly infected with S. rolfsii and contained high total-P content. Thus, minimal P inputs were added to the inoculated soil in the form of rock phosphate. Activities of plant defense enzymes i.e. chitinase, peroxidase and polyphenol oxidase were determined under the greenhouse conditions and the results obtained herein indicated that activities of such enzymes increased significantly owing to bio-agent inoculations. In this concern, combined treatments resulted in further significant increases over the single ones. A field study was then conducted for two successive years and the results reveal that single inoculations increased straw and green pod yields as well as the uptake of P and Fe by plants as compared with the non-inoculated treatment. Combined inoculants recorded further significant increases in these parameters even when compared with the fungicide treated plants. Generally, straw and pod yields obtained from the second growing season were significantly higher than those attained in the first growing one. Our study confirms the success of the used bio-treatments in minimizing soil pollution through fertilizer and/or pesticide inputs.

Evaluating trends in antibiotic resistance is a requisite. The study aimed to analyze the profile of multidrug-resistant organisms (MDROs) among hospitalized patients with bacteremia in intensive care units (ICUs) in a large geographical area. This is a 1-month cross-sectional survey for blood-borne pathogens in 57 ICUs from 24 countries with different income levels: lower-middle-income (LMI), upper-middle-income (UMI), and high-income (HI) countries. Multidrug-resistant (MDR), extensively drug-resistant (XDR), or pan-drug-resistant isolates were searched. Logistic regression analysis determined resistance predictors among MDROs. Community-acquired infections were comparable to hospital-acquired infections particularly in LMI (94/202; 46.5% vs 108/202; 53.5%). Although MDR (65.1%; 502/771) and XDR (4.9%; 38/771) were common, no pan-drug-resistant isolate was recovered. In total, 32.1% of MDR were Klebsiella pneumoniae, and 55.3% of XDR were Acinetobacter baumannii. The highest MDR and XDR rates were in UMI and LMI, respectively, with no XDR revealed from HI. Predictors of MDR acquisition were male gender (OR, 12.11; 95% CI, 3.025-15.585) and the hospital-acquired origin of bacteremia (OR, 2.643; 95%CI, 1.462-3.894), and XDR acquisition was due to bacteremia in UMI (OR, 3.344; 95%CI, 1.189-5.626) and admission to medical-surgical ICUs (OR, 1.481; 95% CI, 1.076-2.037). We confirm the urgent need to expand stewardship activities to community settings especially in LMI, with more paid attention to the drugs with a higher potential for resistance. Empowering microbiology laboratories and reports to direct prescribing decisions should be prioritized. Supporting stewardship in ICUs, the mixed medical-surgical ones in particular, is warranted.

Soil organic carbon plays considerable roles in binding soil particles together forming aggregates. Carbon (C) incorporated within these aggregates is thought to be microbially processed; thus, investigating changes in microbial activities i.e. dehydrogenase, urease, catalase and phosphatase enzymes may explain, to some extent, the dynamics and probably mechanisms responsible of formation of these aggregates. Since, soil water content (SWC) may take part in stimulating/lessening activities of organic matter decomposers; thus, this study aimed at investigating the effects of rice straw as a source of organic C in combination with variable SWC on bioaccumulation of C within different soil aggregate size fractions (2000-250, 250-53 and 53 μm) and hence formation of these aggregates. To achieve these objectives, a pot experiment was conducted for 90 days, including five water levels i.e. maintaining a water head 1 cm above the soil surface (W1), 100% of the saturation percentage, SP (W2), 80% of SP (W3), 65% of SP (W4) and 50% of SP (W5), beside of two rates of applied rice straw i.e. 0 and 15 g kg

Objectives: The objectives of this study are to determine the association between the incidence of attention-deficit and hyperactivity disorder (ADHD) in children of mothers with and without amalgam fillings. Design: The study design was a cross-sectional descriptive study. Setting: The study was conducted at a dental college's clinic in Riyadh, Saudi Arabia. Participants: In total, 869 children (512 males and 357 females) aged 6–12 years and 796 mothers were included. Children suffering from hearing impairment, language impairment, or learning disabilities or those diagnosed with mental health problems were excluded from the study. Primary and Secondary Outcome Measures: The primary outcome measures included the results of the Vanderbilt scale used for ADHD diagnosis in children and the mercury concentration in 1 ml saliva samples obtained from both the mother and the children. The secondary outcome measures included the number of dental amalgam restorations in the oral cavity determined through a dental examination of children and their mothers. Methodology: A consent form was signed by the mothers who agreed to participate in our study, they were all examined for amalgam presence and a saliva samples were collected and digested. Results: Children with ADHD showed significantly higher levels of mercury in saliva than did children without ADHD. The mothers who had dental amalgam fillings during pregnancy had significantly higher mercury levels than did the mothers who did not have dental amalgam fillings. Conclusion: Prenatal mercury exposure is associated with a higher risk of ADHD behavior. Further research can be carried out to identify the toxic effects of mercury on different body organs owing to dental amalgam fillings. The study scale can be further increased to obtain a more accurate percentage of ADHD cases in Saudi Arabia.

We sought to define the type and antibiotic sensitivity response of pathogens isolated from diabetic foot ulcers based on ulcer location and Wagner classification. This retrospective analysis was done among 126 patients between 40 and 70 years of age at the Prince Sultan Military Medical City, Riyadh, Saudi Arabia, using the swab culture method for microbiological assessment. Data on demographic variables, ulcer sites (location), and depth of ulcer (Wagner classification) were also collected. A total of 134 pathogens were isolated from 126 patients. The most common gram-negative pathogen identified was Pseudomonas aeruginosa (15.6%), followed by Klebsiella spp (6.7%). The most common gram-positive pathogen was Staphylococcus aureus (35%), followed by Streptococcus (8.9%). The most widely accepted antibiotic to which the gram-negative bacteria were sensitive was gentamycin (20.1%), followed by ciprofloxacin (19%). The most routinely used antibiotic in the treatment of the gram-positive bacteria was erythromycin (16%), with trimethoprim-sulfamethoxazole (14.1%) being the next most effective. In conclusion, Pseudomonas aeruginosa, Klebsiella spp, Staphylococcus aureus, and Streptococcus were the most common causes of diabetic foot infections. However, the frequency of encountered pathogens and respective sensitivity to antibiotic therapy may be influenced by the location site and severity of the ulceration.

Introduction Media interventions can potentially play a major role in influencing health policies. This integrative systematic review aimed to assess the effects of planned media interventions—including social media—on the health policy-making process. Methods Eligible study designs included randomized and non-randomized designs, economic studies, process evaluation studies, stakeholder analyses, qualitative methods, and case studies. We electronically searched Medline, EMBASE, Communication and Mass Media Complete, Cochrane Central Register of Controlled Trials, and the WHO Global Health Library. We followed standard systematic review methodology for study selection, data abstraction, and risk of bias assessment. Results Twenty-one studies met our eligibility criteria: 10 evaluation studies using either quantitative (n = 7) or qualitative (n = 3) designs and 11 case studies. None of the evaluation studies were on social media. The findings of the evaluation studies suggest that media interventions may have a positive impact when used as accountability tools leading to prioritizing and initiating policy discussions, as tools to increase policymakers’ awareness, as tools to influence policy formulation, as awareness tools leading to policy adoption, and as awareness tools to improve compliance with laws and regulations. In one study, media-generated attention had a negative effect on policy advocacy as it mobilized opponents who defeated the passage of the bills that the media intervention advocated for. We judged the confidence in the available evidence as limited due to the risk of bias in the included studies and the indirectness of the evidence. Conclusion There is currently a lack of reliable evidence to guide decisions on the use of media interventions to influence health policy-making. Additional and better-designed, conducted, and reported primary research is needed to better understand the effects of media interventions, particularly social media, on health policy-making processes, and the circumstances under which media interventions are successful.

Adriamycin (Adr) is a cytotoxic anthracycline agent that is utilized to manage many types of tumors, but its clinical use is undesirable due to severe cardiotoxicity. The present study aimed to investigate the cardioprotective effect of Achillea fragrantissima (A. fragrantissima) against Adr-induced cardiotoxicity through the antioxidant and anti-inflammatory metabolic pathways. A single dose of Adr was injected in rats to induce cardiotoxicity. Rats are divided into 5 groups, control, A. fragrantissima 800, Adr, A. fragrantissima 400 + Adr, and A. fragrantissima 800 + Adr. 72 h after Adr administration, electrocardiographic (ECG) study was performed for all rats. Serum and hearts were then collected for biochemical and histopathological studies. A. fragrantissima ameliorated Adr-induced ST-segment elevation. It reduced Adr-induced elevation in lactate dehydrogenase (LDH), creatine kinase-MB (CK-MB), thiobarbituric acid reactive substance (TBARS), tumor necrosis factor-alpha (TNF-α), interleukin-1 beta (IL-1β), and IL-6. It also protected against Adr-induced histopathological changes. Pretreatment with the extract increased heart tissue contents of glutathione peroxidase (GSH-PX) and reduced glutathione (GSH). Phytochemical analysis of the extract revealed that it is rich in phenolic and flavonoid active constituents. The results of this study revealed that A. fragrantissima extract ameliorates Adr-induced cardiotoxicity via an antioxidant and anti-inflammatory mechanisms. Further studies are warranted in order to recognize the precise active constituents of this natural extract which are responsible for the antioxidant and anti-inflammatory actions.

The current study aims to investigate the implications of amending a soil contaminated with Cd with peanut residues biochar (BP) solely or in combination with cow manure (CMPB) at different rates on phytotoxicity of Cd for wheat plants and its distribution in a mine contaminated soil. Soil pH and EC increased progressively in soils amended with either PB or CMPB. Exchangeable Cd was decreased while its non-exchangeable fractions were increased. Dry weights of wheat straw, roots and grains increased when soils amended with either PB or CMPB, especially at the higher application rate. Such increases were correlated significantly with the extractable soil-Cd. Concentrations of Cd in roots were higher than those in straw; whereas, the concentrations in grains seemed to be the lowest. Generally, values of bio-concentration and translocation factors did not exceed "1" and decreased with application of either PB or CMPB. In conclusion, enriching biochar with cow manure is a recommended strategy to reduce Cd uptake and translocation to straw and seeds. Moreover, Concentrations of Cd did not exceed the permissible levels in grains when soils amended with the highest rate of CMPB.

Chemical fungicides are effective tools in controlling plant pathogens; however, these chemicals can, on the other hand, distress the ecosystem. Accordingly, the current research investigates the potentiality of substituting traditional chemical fungicides by inducing plant resistance against infection with soil-born pathogens i.e. Sclerotium rolfsii in the presence of mycorrhizae (AMF) as plant inoculants and one of the following amendments: humic acid, sulphex (a mixture of canola oil and diluted sulphuric acid) and paclobutrazol (ABZ). To attain the abovementioned objective, a field (mildly infected with S. rolfsii) was cultivated with Helianthus tuberosus (a perennial plant belongs to the Asteraceae family) for two successive seasons (2014 and 2015) and the above-mentioned treatments were tested for their feasibilities in controlling S. rolfsii infection against the chemical fungicide “Vitavax-200” either solely or in combinations in a complete randomized block design. Inoculating plants with AMF or amending soils with either humic acid, Sulphex or ABZ solely increased significantly the activities of plant defense enzymes by approximately 1.5–2.1 folds higher than the control treatment. These treatments also improved NPK availability in soil and; hence, increased their contents within plant tubers. Consequently, these treatments decreased the disease incidence and severity caused by S. rolfsii while improved shoot biomass and tuber yield. In spite of that, these results stood below the prospective of the fungicide treatment. The integrated treatments i.e. “humic acid + AMF”, “Sulphex + AMF” and “ABZ + AMF” caused further significant improvements in both NPK availabilities in soil and plant areal bio-masses. This probably induced further plant resistance against the investigated soil-borne pathogen while recorded insignificant variations in disease incidence and severity when compared with the fungicide treatment. Moreover, the integrated treatments increased the tuber yields beyond those attained for the fungicide treatment. Accordingly, such integrated strategies can completely substitute the chemical fungicides; thus, minimize their negative impacts on the ecosystem.
