GLYCOPEPTIDES , *MICROBIAL virulence , *VANCOMYCIN resistance , *ENTEROCOCCUS , *POLYMERASE chain reaction - Abstract
Objective: This study aimed to identify glycopeptide resistance genes and virulence factors in vancomycin-resistant Enterococcus species and to investigate the influence of the microbiota and hospital environment on glycopeptide resistance. Materials and Methods: A total of 107 enterococcal isolates were collected from patients' rectal swab cultures and environmental samples taken for surveillance purposes. Multiplex Polymerase Chain Reaction (PCR) analysis was conducted to investigate specific virulence genes (esp, hyl, asa1, cyl, and galE) and glycopeptide resistance genes (vanA, vanB, van C1-C2, van D, vanE, and vanG). Additionally, perirectal swab cultures were obtained from patients without vancomycin-resistant enterococcal colonization to investigate the presence of glycopeptide resistance genes in their microbiota. Results: Seven isolates (6.5%) were identified as infectious agents. The most common vancomycin resistance genes were vanA (23.3%), followed by vanA + vanB (14%) and vanB + vanD (14%), respectively. The Random Amplified Polymorphic DNA Polymerase Chain Reaction (RAPD-PCR) method showed that patient surveillance and environmental isolates were clonally related. Moreover, microbiota analysis of patients without vancomycin-resistant enterococcal colonization revealed Clostridium spp. in two patients and Lactobacillus spp. in one patient, with the vanG gene found in the microbiota of only one (2.5%) patient. Conclusion: The detection of genes responsible for dissemination indicates that colonized isolates also have the potential for infection, and the hospital environment plays a primary role in the acquisition of vancomycin-resistant enterococci.

EARTHQUAKES , *MEDICAL care , *INFECTION , *BIOSECURITY , *COMMUNICABLE diseases - Abstract
On February 6, 2023, Türkiye experienced two significant earthquakes with magnitudes 7.7 Mw and 7.6 Mw at 04:17 Türkiye Standard Time (TRT) (01:17 Coordinated Universal Time (UTC)) and 13:24 TRT (10:24 UTC), respectively, centered in Kahramanmaraş. The study aims to review the immediate aftermath of these earthquakes, their impact on health services, and the potential threats of infection due to these catastrophic events in Türkiye. Eleven provinces in the southeastern region of Türkiye, as well as areas in the northwestern region of Syria, suffered severe damage. Aftershocks continue, though with decreasing intensity. Thousands of structures, including crucial infrastructure, were destroyed. Approximately 15 million people in Türkiye and 10.87 million people in Syria were severely affected. About 200.000 people were injured, and more than 50.000 people died due to the earthquakes. Roughly 500.000 people fled from the earthquake-affected region to western cities. The rescue operations were completed within two weeks. The earthquake and its aftershocks, compounded by winter conditions, left thousands of people homeless in the region. Intensive efforts were initiated to address the health care, medicine, shelter, nutrition, sanitation, and other needs of the earthquake victims. In the upcoming days, earthquake survivors may face significant risks of infections, including airborne, food-borne, and water-borne infections, as well as nosocomial infections from resistant bacteria and parasitic infections. Identifying the risk factors that underlie the emergence and transmission of communicable diseases can enhance the development and implementation of more effective preventive measures. Currently, safety, security, mitigation, and infection control activities are essential to help restore daily life in the region. [ABSTRACT FROM AUTHOR]

FUSARIOSIS , *HEMOPHAGOCYTIC lymphohistiocytosis , *SEPTIC shock , *GENETIC mutation , *HOSPITAL admission & discharge - Abstract
Background: Hemophagocytic lymphohistiocytosis (HLH) is classified as primary or secondary. While primary (familial) HLH is caused by genetic mutations, secondary (acquired, reactive) HLH is the type that has an underlying cause and is not associated with genetic mutations. Case Report: We report a two-year-old female patient with a fatal course of Fusarium sepsis who was diagnosed with primary HLH. A homozygous variant of PRF1 (c.445G > A, p.Gly149Ser) was detected. Hyphal growth was detected on Sabouraud dextrose agar and Fusarium multiplied in blood cultures. The patient's clinical course was fulminant, and she died of septic shock 4 days after admission to the hospital. Fusarium, a rare infection in HLH, was found in this case. Conclusion: We discovered the rare PRF1 (c.445G>A, p.Gly149Ser) mutation in HLH and the high morbidity and mortality associated with Fusarium infection. [ABSTRACT FROM AUTHOR]

Aim: Widespread and repeated use of azoles for prophylaxis or therapy has led to the development of resistance in Candida albicans species.In this study, it was aimed to determine the in vitro resistance rates of Candida albicans isolates isolated from sterile body fluid cultures to fluconazole, itroconazole and voriconazole.Material and Methods: Candida albicans species isolated from sterile body fluid cultures sent from various clinics between January 2020 and April 2021 were included in the study.Species-level identification was assessed using conventional methods and the BD Phoenix 100 (BD, USA) automated identification system. Antifungal susceptibility testing was performed by microdilution method using RPMI medium containing 2 % glucose according to EUCAST recommendations.For the triazoles fluconazole, itroconazole and voriconazole, the concentration in the well at which turbidity was reduced significantly (≥50%) was determined as the MIC50 value. C.albicans ATCC 90028 was used as control strain.Results: It was found that 51/99 (51.5%) of the candidemia agents were Candida albicans.88.2% (n=45) of Candida albicans isolates were isolated from samples taken from intensive care units.Twenty-six (50.9%) of the samples were taken from female patients with a mean age of 68.6 ± 18.29 years, and 25 (49%) from male patients with a mean age of 62.22 ± 21.08 years. One (1.9 %) of the isolates were identified from cerebrospinal fluid, 1 (1.9 %) sterile body fluid, 1 (1.9 %) bronchoalveolar lavage, and 48 (94.1%) blood cultures. According to the antifungal susceptibility test results; 7 (12.2 %) of the species were resistant to fluconazole, 14 (27.4 %) to itroconazole, and 2 (3.9%) to 5 (9.8 %) voriconazole. Cross-resistance was detected in a total of 6 (11.7 %) samples.Conclusion: C. albicans is still the most frequently isolated species among the candidemia agents detected in our hospital. Cross-resistance to other triazoles was observed along with azole resistance. Therefore, antifungal susceptibility test results should be taken into account for appropriate treatment., Amaç: Azollerin profilaksi veya tedavi amacıyla yaygın ve tekrarlayan kullanımı Candida albicans türlerinde direnç gelişimine yol açmıştır.Bu çalışmada, steril vücut sıvısı kültürlerinden izole edilen Candida albicans izolatlarının flukonazol, itrokonazol ve vorikonazole in vitro direnç oranlarının belirlenmesi amaçlanmıştır.Gereç ve Yöntemler: Ocak 2020 ile Nisan 2021 arasında çeşitli kliniklerden gönderilen steril vücut sıvı kültürlerinden izole edilen Candida albicans türleri çalışmaya dahil edildi.Tür düzeyinde tanımlama, geleneksel tanı yöntemleri ve BD Phoenix 100 (BD, ABD) otomatik tanımlama sistemi kullanılarak yapıldı. Antifungal duyarlılık testi EUCAST önerilerine göre; % 2 glukoz içeren RPMI kullanılarak mikrodilüsyon yöntemiyle değerlendirildi.Triazoller olan flukonazol, itrokonazol ve vorikonazol için bulanıklığın belirgin (≥ % 50) olarak azaldığı kuyucuktaki konsantrasyon, MİK50 değeri olarak belirlendi. Çalışmada kontrol suş olarak C.albicans ATCC 90028 kullanıldı.Bulgular:Kandidemi etkenlerinin 51/99 (% 51.5)’unun Candida albicans olduğu görüldü. Candida albicans izolatlarının % 88.2'si (n=45) yoğun bakım ünitelerinden alınan örneklerden izole edildi. Örneklerin 26 (% 50.9)’sı yaş ortalaması 68.6 ± 18.29 yıl olan kadın hastalardan, 25 (% 49)’i yaş ortalaması 62.22 ± 21.08 yıl olan erkek hastalardan alındı. İzolatların 1 (% 1.9)’i beyin omurilik sıvısı, 1 (% 1.9)’i steril vücut sıvısı, 1(% 1.9)’i bronkoalveolar lavaj, 48 (% 94.1)’i kan kültürlerinden tanımlandı. Antifungal duyarlılık test sonuçlarına göre türlerin7(% 12.2)’si flukonazol, 14 (% 27.4)’ü itrokonazol ve 5 (% 9.8)’i vorikonazole dirençli bulundu. Toplam 6 (% 11.7) örnekte ise çapraz dirence rastlandı.Sonuç: C. albicans, kandidemiye neden olan ajanlar arasında hala en sık izole edilen türdür. Azol direnci ile birlikte diğer triazollere karşı da çapraz direnç gözlenmiştir. Bu nedenle uygun tedavi için antifungal duyarlılık test sonuçları dikkate alınmalıdır.

LEGIONELLA pneumophila , *ACINETOBACTER baumannii , *PATHOGENIC microorganisms , *MECHANICAL ventilators , *INTENSIVE care units , *WATER sampling - Abstract
Objective: In this study, it was aimed to investigate Legionella spp. and other pathogenic microorganisms in swab samples taken from different units of a tertiary healthcare hospital between July 25, 2019 and November 1, 2019. Materials and Methods: Ninety-two swab samples were taken from the mechanical ventilator, air conditioner filters, water outlets, and sink faucets in the laboratory, operating room and different intensive care units of the hospital. All samples were centrifuged and inoculated directly onto buffered coal yeast extract agar, a medium selective for Legionella and other conventional media. 16S rRNA sequence analysis was performed for identification at the species level by randomly selecting 6 samples that were positive for Legionella by culture and serological tests. Results: Growth compatible with Legionella spp. colonies was observed in 24 (26.08%) cultures. Only three of the 6 serogrouped samples were confirmed by molecular identification. Two of these were identified as Legionella pneumophila subsp. pneumophila and the other as Legionella anisa. Penicillium spp., Aspergillus flavus, Acinetobacter baumannii, Morganella morganii, Moraxella spp., and Pseudomonas aeruginosa were isolated from the filters of mechanical ventilators and Escherichia coli from a tap sample. Conclusion: Potential Legionella spp. exposure in high-risk patients should be eliminated with increased sampling frequency and effective control measures. [ABSTRACT FROM AUTHOR]

Amaç: S.maltophilia düşük patojenite özelliklerine rağmen, immün düşkün ve yoğun bakım ünitelerinde uzun süre yatan hastalarda kolonize olabilen, solunum ve gastrointestinal sistemden seçilerek sıklıkla pnömoni ve bakteriyemi gibi enfeksiyonlara neden olabilen bir mikroorganizmadır. Özellikle kistik fibrozisli hastaların risk altında olduğu bilinmektedir. Çalışmamızın amacı, S. maltophilia izolatlarını ve trimetoprim-sülfometaksazol(TMP-SXT) duyarlılık durumunu inceleyerek lokal epidemiyolojik veri elde etmektir.Gereç ve Yöntem: 1 Ocak 2018-31 Mayıs 2019 tarihleri arasında Kahramanmaraş Sütçü İmam Üniversitesi Tıp Fakültesi Hastanesi’ne gelen hastaların kültür örneklerinden izole edilmiş 96 S. maltophilia izolatı retrospektif olarak incelenmiştir.Bulgular: S.maltophilia’nın önemli bir kısmı (%50) solunum yolu örneklerinden izole edilmiş, TMP-SXT’ye direnç %1,04’si (n=1) olarak bulunmuştur.Sonuç: Stenotrophomonas maltophilia ‘nın birçok antibiyotiğe dirençli olması tedavide güçlüklere neden olmaktadır. TMP-SXT Stenotrophomonas maltophilia enfeksiyonlarında hala kullanılabilecek en etkili antibiyotiktir. Özellikle kültür örneklerinden S. maltophilia izole edildiğinde etken –kolonizasyon ayırımı yapılmalı ve gereksiz antibiyotik kullanımından kaçınılarak direnç gelişimi önlenmelidir., Objectives: S.maltophilia despite its low pathogenicity, can cause colonization in immunocompetent and long-term inpatients in the intensive care unit, and can cause pneumonia and bacteremia, often selected from the respiratory and gastrointestinal tract. It is known that especially cystic fibrosis patients are at risk.The aim of this study was to obtain local epidemiological data by examining S. maltophilia isolates and trimetoprim-sulfometaxazole (TMP-SXT) susceptibility.Methods: Ninetysix S. maltophilia isolates, isolated from culture samples sent to Kahramanmaraş Sütçü İmam University Medical Faculty Hospital Microbiology Laboratory between January 1, 2018 and May 31, 2019 were analyzed retrospectively.Results: A significant portion (50%) of S.maltophilia was isolated from respiratory tract samples and resistance to TMP-SXT was found to be 1.04% (n = 1).Conclusion: Stenotrophomonas maltophilia is resistant to many antibiotics, causing treatment difficulties. TMP-SXT is the most effective antibiotic that can still be used in Stenotrophomonas maltophilia infections.Especially when S. maltophilia is isolated from cultural examples, pathogen/ colonization should be differentiated and resistance should be prevented by avoiding unnecessary antibiotic use.

Objective: Human immunodeficiency virus (HIV) false positivity is one of the common misdiagnoses in laboratories. Thus, only positive results obtained by confirmatory tests should be considered positive while other types of screening tests should instead be referred to as reactive. This study investigated false HIV positivity via the sociodemographic characteristics of the patient, clinical diagnosis, and the relationship with the drugs used. Materials and Methods: From January 2017 to October 2018, 25,180 patients were tested for HIV with the fourth-generation antigen/antibody EIA. Reactive test results were sent to the Public Health Institution in Turkey to confirm the test results with immunoblot or polymerase chain reaction. Results: Of the samples, 23 (0.091%) and 113 (0.44%) were found to be HIV-positive and HIV-negative. Confirmation tests were performed on 136 samples. Consequently, 113 samples were confirmed to be negative and, therefore, considered as false positives. A distributional relationship was found between HIV false positivity and patients hospitalized in clinics of infectious diseases, hematology, and orthopedics (X2=49.048; p=0.001), and patients diagnosed with neoplasm or soft tissue infection (X2=51.699; p=0.001). Moreover, the rate of false positivity significantly increased with the use of antibiotics, steroidal/nonsteroidal drugs, immunoglobulin preparations, and antithrombotic drugs. Conclusion: Since HIV tests used in a low prevalence population are commonly testing low-risk individuals, the reactive tests can lead to false-positive results rather than true-positive. Thus, screening test results alone should not be relied upon for this diagnosis. [ABSTRACT FROM AUTHOR]

Background: Clostridium tetani is an anaerobic, gram-positive bacillus that causes tetanus infection. It usually enters the body through injury with contaminated objects. Tetanus differs from other diseases that can be prevented by vaccination in that it is not contagious and does not spread from person to person. The aim of this study is to evaluate the levels of Tetanus IgG in trauma patients admitted to the emergency department (ED). Methods: The study was planned as cross-sectional, prospective, and single-center. The study was conducted from January to July 2018 in the Kahramanmaraş Sütçü İmam University Hospital. Totally, 178 patients aged ≥18 years were included. For measurement of the level of Tetanus IgG, Clostridium tetani toxin 5S IgG kit (NovaLisa, NOVATEC) was used to quantitatively detect IgG type antibodies by micro-ELISA method in accordance with the manufacturer's recommendation. Results: In total, 143 cases were male and 35 were female. The mean age of the cases was 40 ± 16 years. Tetanus IgG levels were found to be 0.29 ± 0.6 IU/mL in cases from rural areas and 2.14 ± 1.64 IU/mL in cases from urban areas (P < 0.001). There was a negative correlation between age and Tetanus IgG level (r: (-) 0.479; P < 0.001). The protective level of Tetanus IgG was observed to be even lower, especially in patients aged ≥40 years (n = 43, 78.9%). Conclusion: Measurements of Tetanus IgG levels should be performed as far as possible in the ED. In this way, unnecessary vaccination can be avoided. [ABSTRACT FROM AUTHOR]

ÖZET Hastane Enfeksiyonuna Neden Olan Gram-Negatif Bakterilerde Direnç Paterni ve Genişlemiş Spektrumlu Beta-Laktamaz (ESBL) Tayini Bu çalışma, Çukurova Üniversitesi Tıp Fakültesi, Balcalı Hastanesi'nde hastane enfeksiyonu (HE) olan hastalardan alınan örneklerden izole edilen Gram-negatif bakterilerde direnç paterni ile genişlemiş spektrumlu beta-laktamaz (extended spectrum of beta- lactamases: ESBL) varlığım araştırmak ve ESBL tespitinde kombine disk testi (KDT), E- test ve çift disk sinerji test (ÇDST)'lerini karşılaştırarak en uygun yöntemi bulmak için amaçlanmıştır. Çukurova Üniversitesi Tıp Fakültesi, Balcalı Hastanesi Merkez Laboratuvarı, Mikrobiyoloji Birimi'ne 29. 05. 2003-30. 09. 2004 tarihleri arasında gönderilen 93 hastaya ait 1 15 örnekte HE kökenli 68 Escherichia coli ve 47 Klebsiella spp. susu izole edilmiştir. Suşların çoğunluğu (% 53) üriner sistem enfeksiyonu (ÜSE) olan hastalardan elde edilmiştir. HE kökenli bu suşların duyarlılıkları disk diffüzyon testi (DDT) ile araştırılmıştır. Genel olarak trimetoprim/sülfometaksazol, üçüncü kuşak sefalosporinler ve aztreonam'a direnç saptanırken, en az direnç görülen antibiyotik imipenem olmuştur. Çalışmamızda DDT ile seftazidim, seftriakson, sefotaksim ve aztreonam yönünden ESBL şüpheli bulunan izolatlar ÇDST, KDT ve E-test ESBL testleri ile pozitiflikleri doğrulanarak testler arasında karşılaştırma yapılmışta. Klebsiella spp. suşlarında E-test ile 47 susun 30 (% 63.80)'unda, ÇDST ile 27 (% 57.44)'inde ve KDT ile 21 (% 44.68)'inde ESBL pozitifliği belirlenmiştir. E. coli suşlarında ise E-test ile 68 susun 42 (% 61.76)'sinde, ÇDST ile 36 (% 52.54) ve KDT ile 34 (% 50)'ünde ESBL pozitif bulunmuştur. KDT, ESBL tespiti için referans test olarak kabul edildiğinde KDT ile ESBL negatif bulunan 60 sustan 18'i DDT, 17'i E-test, ve 8 suş ise ÇDST ile pozitif bulunmuştur. Sonuç olarak DDT ve E-testin ÇDST'ye göre daha yüksek sayıda yalancı pozitiflik vermesi ve ayrıca E-testinde bazen klavulanik asitin beta-laktam antibiyotik tarafına diffüzyonu sonucu değerlendirme zorluğu yaratması ve pahalı olması sebebiyle ESBL tesbitinde uygulaması daha kolay ve ucuz yöntemler olan KDT ve ÇDST yöntemleri tercih edilebilir.

The 68 E. coli and 47 Klebsiella spp. strain of nosocomial origin were isolated from 115 specimens of 93 patients between 29.05.2003 and 30.09.2004 in Çukurova Uni versity, Faculty of Medicine, Balcali Hospital Central Laboratory Microbiology Depart ment. Most of the strains (% 53) were isolated from patients who had urinary tract infec tions (UTI). The sensitvity of these nosocomial strains were detected by disc diffusion test (DDT). Altough there was a general resistance against trimethoprim/sulfomethoxasol, third generation cepholosporins and aztreonam, the least resistance was against imipenem. In this study, isolates that found to be suspicous for ESBL against ceftazidime, ceftriaxone, cefotaxime, and aztreonam by DDT were also studied by DDST, CDT and E- test ESBL test and after the confirmation of positivity, the tests were compared. ESBL positivity among Klebsiella spp. was detected in 30 of 47 strains (63.8 %) by E-test, 27 (57.44 %) by DDST, 21 (44.68 %) by CDT. Among E. coli strains, ESBL positivity was found in 42 of 68 (61.76 %) strains by E-test, 36 (52.54 %) by DDST, 34 (50 %) by CDT. Of 60 strains found to be ESBL negative by CDT, which is accepted as the referance test for identification of ESBL, 18 strains by DDT, 17 strains by E-test, 8 strains by DDST were detected ESBL positive. Consequently, as DDT and E-test have a higher false positivity than DDST, and besides in E-test the difficulty in evaluation of the results in which clavulanic acid occasionally diffuses over the site of beta-lactam antibiotic and its high cost, CDT and DDST would be preferred for detection of ESBL because of their practical use and low cost. Key words: ESBL, E. coli, Klebsiella spp., combined disc test, nosocomial infection. IX 84

- Abstract
Objective: To examine the in vitro antifungal effects of water-soluble pure elemental boron with an alkaline solution against Candida species, Trichophyton species, and Aspergillus fumigatus that cause superficial mycosis., Methods: The study was conducted at the microbiology laboratory of Kahramanmaras Sutcu Imam University Hospital, Kahramanmaras, Turkey, from June to December 2018, and comprised fungal strains isolated from patients with superficial mycosis who visited the dermatology clinic. The in vitro antifungal effects of the boron solution at various concentrations were determined using the microbroth dilution method. Candida albicans ATTC 90028 and Candida albicans MYA 274 served as the quality control strains, while fluconazole and amphotericin B were used as comparator antifungal agents. Data was analysed using SPSS 22., Results: Of the 58 strains, 28(48.3%) were Candida albicans, 9(15.5%) non-Candida albicans, 12(20.7%) Trichophyton rubrum, 4(6.9%) Trichophyton mentagrophytes, 2(3.4%) Trichophyton species and 3(5.2%) were Aspergillus fumigates. Boron at a concentration of 78.125 μg/mL inhibited the growth of Candida albicans. The 50% and 90% minimum inhibitory concentrations of the solution in non-Candida albicanswere 78.125 and 312.5 μg/mL, respectively, whereas those in Trichophyton rubrum were 312.5 and 625 μg/mL, respectively. The 50% minimum inhibitory concentration of the solution in Aspergillus fumigatus was 625 μg/mL, whereas the 90% minimum inhibitory concentration could not be determined., Conclusions: Boron is an inexpensive, non-antibiotic element with potential uses as an antifungal agent.
