Background. Parasitic diseases, in particular leishmaniasis, are still a public health problem in several countries and in Morocco. Methods. The data used are those of epidemiological surveillance collected in the registers of the prefectural epidemiology cell (PEC); however, the socioeconomic data were obtained from the High Commissioner for Planning. The Pearson correlation test was used to determine the correlation between the different variables. Results. In total, 70 cases were recorded by the prefectural epidemiology cell (PEC) during the period from 2009 to 2015. 46% of the cases come from rural areas while 54% of the cases come from urban areas. The Pearson test shows the existence of a significant relationship between the number of cases recorded and the type of environment (r = 0.49, p value = 0.02), and population rate (R = 0.849 and p ≤ 0.001). However, in our case, the poverty rate does not influence CL's distribution. Conclusion. Our results show that the CL affects the majority of the municipalities with predominance of the urban environment, so the distribution of cases of this pathology is not influenced by the poverty; however, the urbanization and the number of inhabitants have a positive impact on the distribution of this scourge.

The hospital environment, especially medical devices and surfaces, represents a secondary reservoir for pathogens. This work aims to evaluate the microbiological quality of surfaces and medical equipment of controlled environment services (burn unit, operating room, and sterilization service) at a hospital in Meknes (center of Morocco). This study was carried out for three months (September-December of 2017). A total of 63 samples were taken by swabbing technique from different surfaces and medical equipment after bio-cleaning. Identification was performed according to conventional bacteriological methods and by microscopic observation for fungi. The study showed that 68% of the surface was contaminated. The operating room recorded a rate of 93% of contamination (p-value

Wastewater and human excreta are threatening the quality of groundwater and watercourses in rural areas of Morocco. The new sanitation approach that has advantage to solve the problems of pathogens of human waste at source and offering the possibility of reusing them after treatment is called Ecological Sanitation (EcoSan) could be an alternative solution to the conventional one. It is in this perspective that our study made an investigation on economic, ecological, sustainable sanitation techniques adapted to the Moroccan context. Indeed, a survey was carried out at Dayet Ifrah village to assess the population appreciation of the EcoSan structures installed. Survey results showed that these structures have been generally accepted by almost all users and non-users (95%). On the other hand, a pilot-scale system composed by two types of filters (vertical constructed wetland and vertical Multi-Soil-Layering) have been installed in order to treat domestic wastewater coming from a single household and their performance was evaluated. The filters showed good performance to remove organic pollution (> 84.5%) and orthophosphate (> 68%). The reduction of ammonium were 84.5% and 35.3% for vertical Multi-Soil-Layering and vertical constructed wetland, respectively. The quality of the wastewater treated was evaluated in accordance with the standard of the rejection limit value adopted by Morocco.

The present study was conducted to better understand the specific contingency of extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli (E. coli) isolated from urban waters of Wadi Ouislane of the city of Meknes, compared to isolates from patients hospitalized in the resuscitation department at Mohamed V Hospital in Meknes, Morocco. These antibiotic-resistant bacteria have become ubiquitous in effluents, creating increasing concern about their potential impact on human and animal health and the environment. We took four samples of wastewater representative of a day, effluents of the wadi Ouislane. They were analyzed for indicator germs of fecal pollution, namely total coliforms (TC) and fecal coliforms (FC). Bacteria were enumerated by the dilution-filtration technique and by incorporation in solid medium in supercooling. However, four bacteriological samples, taken for clinical purposes from hospitalized patients, were performed at the medical analysis laboratory of Mohamed V Hospital in Meknes. Analysis of our results showed that ESBL-producing E. coli bacteria isolated from our effluents had the same antibiotic resistance profiles as those from hospitalized patients. Urban wastewater discharges into the environment contribute to the dissemination of extended-spectrum beta-lactamase-producing Escherichia coli that may pose health risks to the population.

Background: Equipment and hospital surfaces constitute a microbial reservoir that can contaminate hospital users and thus create an infectious risk. The aim of this work, which was carried out for the first time at a hospital in Meknes (regional hospital in the center of Morocco), is to evaluate the microbiological quality of surfaces and equipment in three potential risk areas (burn unit, operating room, and sterilization service)., Methods: This study was carried out over a period of 4 months (February-May 2017). A total of 60 samples were taken by swabbing according to the standard (ISO/DIS 14698-1 (2004)) in an environment of dry area and equipment after biocleaning. Isolation and identification were performed according to conventional bacteriological methods and by microscopic observation for fungi., Results: The study showed that 40% of surface samples were contaminated after biocleaning. The burn unit recorded a percentage of 70% contamination ( p value <0.001), 13% for the sterilization service, and 7% for the operating room. 89% of the isolates were identified as Gram-positive bacteria against 11% for fungi ( p value <0.001). Bacterial identification showed coagulase-negative staphylococci (32%), Bacillus spp. (16%), Corynebacterium (8%), and oxidase-negative Gram-positive bacillus (40%) while fungal identification showed Aspergillus niger ( n  = 2) and Aspergillus nidulans ( n  = 1)., Conclusion: To control the infectious risk related to equipment and hospital surfaces, it would be necessary to evaluate the disinfection protocol applied in these units., Competing Interests: The authors declare that they have no conflicts of interest., (Copyright © 2020 Samira Jaouhar et al.)

From 123 clinical and environmental Pseudomonas aeruginosa isolates, 24 strains were selected for their similar antibioresistance, virulence and biofilm formation profiles, to examine their diversity and occurrence of clones within two hospitals and different natural sites in Meknes (Morocco). Pulsed-field gel electrophoresis, using DraI enzyme, didn't reveal a close relationship between clinical and environmental isolates nor between strains of the two hospitals. 19 genotypes were obtained, including two virulent environmental clones and three clinical clones virulent and resistant to antibiotics. Intra-hospital transmission of high-risk clones detected, in and between wards, constitutes a great public health concern.

The emergence and the rapid spread of Pseudomonas aeruginosa carrying carbapenemases represent a serious threat to public health due to their delicate therapy. This work was performed to establish the resistance profile and to detect carbapenemases producing in 123 P. aeruginosa isolates. Among these 55 are environmental isolates and 68 are from the two major hospitals of Meknes-Tafilalet region in Morocco. All strains were tested against 14 antipseudomonal drugs by disc diffusion method. On carbapenem resistant strains minimum inhibitory concentrations of imipenem were determined by the E-test method. The modified Hodge test and EDTA tests were used for the detection of carbapenemases and metallo-β-lactamases (MBLs), respectively. PCR and DNA sequencing were conducted to detect carbapenemase-encoding genes and the enzyme types. 12% of isolates was susceptible to all antibiotics tested and Carbapenem resistance was observed in 33 P. aeruginosa isolates, 33.3% of them were multi-drug resistant. Among carbapenem resistant strains only two (6.1%) were positive for carbapenemases and also for MBLs. In addition to their resistance to almost all β-lactams tested, the MBLs producing strains were resistant to aminoglycosides. Molecular biology techniques confirmed the phenotypic results obtained for the two strains carbapenemase producers and demonstrated that each one of them carried blaVIM-2. The present study reports the first isolation of blaVIM genes in clinical isolates of P. aeruginosa in Morocco. Such isolates represent a serious emerging threat requiring strict hygiene measures to better control their spread., (Copyright © 2015 Japanese Society of Chemotherapy and The Japanese Association for Infectious Diseases.
