Virulence Factors And Antimicrobial Resistance In Uropathogenic Escherichiacoli Strains Isolated From Cystitis And Pyelonephritis, Hosseinali Ghazvini, Keyvan Taheri, Elahe Edalati, Ali Miri, Mansour Sedighi, Shiva Mirkalantari
Turkish Journal of Medical Sciences
Background/aim: The aim of this study was to investigate the prevalence of virulence genes as well as patterns of antibiotic resistance in cystitis and pyelonephritis uropathogenic Escherichia coli (UPEC) isolates. Materials and methods: Two hundred UPEC isolates were collected from hospitalized patients with pyelonephritis (n = 50) and cystitis (n = 150) in Shafa Hospital in Iran. Antimicrobial susceptibility and ESBL production were determined with confirmatory tests. Polymerase chain reaction assay was performed to determine the prevalence of virulence genes in UPEC strains. Results: Of a total 200 UPEC isolates, the highest and lowest resistance rates to antibiotics were for …
Biofilm Formation In Uropathogenic Escherichia Coli: Association With Adhesion Factor Genes, Hojjatolah Zamani, Ali Salehzadeh
Biofilm Formation In Uropathogenic Escherichia Coli: Association With Adhesion Factor Genes, Hojjatolah Zamani, Ali Salehzadeh
Turkish Journal of Medical Sciences
Background/aim: Biofilm formation is a major determinant factor in the development of urinary tract infections (UTIs) by uropathogenic Escherichia coli (UPEC). Several adhesion factors are involved in attachment of bacterial cells to the urinary tract and biofilm development. Materials and methods: The possible relationship between different adhesion factor genes (AFGs) and biofilm formation among UPEC isolates was investigated. Prevalence of different AFGs including fimA, fimH, papAH, papC, papEF, sfa-S, foc/G, and bmaE and their association to biofilm formation were investigated. Phenotypic expression of type 1 and P fimbriae was also investigated. Results: Our results showed that 84% of UPEC were …

Fecal Carriage Of Extended-Spectrum Beta-Lactamase-Producing Escherichia Coli And Klebsiella Spp. In A Turkish Community, Derya Çakir Erdoğan, Füsun Cömert, Eli̇f Aktaş Sepetci̇, Fürüzan Köktürk, Canan Külah
Turkish Journal of Medical Sciences
Background/aim: The aim of this study was to determine the prevalence of fecal carriage of extended-spectrum beta-lactamase (ESBL)-producing bacteria, enzyme types, and risk factors affecting colonization. Materials and methods: A total of 576 stool samples from outpatients were examined between October 2012 and May 2013. Screening was done with selective EMB plates. ESBL were detected by double-disk synergy and confirmed agar strip gradient methods. Enzyme types were determined by PCR. Results: The prevalence of fecal carriage was found as 30% (173 of 576). Recent use of antibiotics, hospitalization and surgical operation, diabetes, crowded household populations, and old age were associated …

To investigate whether prostatic inflammation affects the contractile responses of prostate tissue and then whether melatonin has any restorative effect on the contractile responses in a rat model of bacterial prostatitis at early stages. Materials and methods: We evaluated the nerve-evoked, adrenergic agonist-induced or cholinergic agonist-induced contractions of isolated prostate tissue at 24 and 72 h after intraurethrally instilled Escherichia coli-treatment. We also analyzed the histological changes in the prostate. Secondarily, we investigated the effect of melatonin pretreatment (7 days, 10 mg kg^{-1} day^{-1}) on the contractile responses and the histopathologic changes. Results: The degrees of acute inflammatory cell infiltration, …

Histopathological Effects Of S. Xylosus Peptidoglycan In Comparison To E. Coli Lipopolysaccharide In The Urinary Tract Of Mice, Harith Jabbar Fahad Al-Mathkhury, May Talib Flaih, Hiba Khalil Tawfiq
Turkish Journal of Medical Sciences
The present work, among other previous studies done in our lab, aimed to highlight the histopathological effect of S. xylosus peptidoglycan in comparison to LPS of E. coli. Materials and methods: One hundred and fifty urine specimens were collected from urinary tract infection patients visiting Baghdad hospitals. The histopathological effects of S. xylosus S24 peptidoglycan was studied in the urinary tract of female mice by injecting 5 animal groups at the following concentrations: 1000, 2000, 3000, 4000, and 5000 µg/mL. Another 5 groups were injected with 10, 25, 50, 75, and 100 ng/mL of E. coli (serotype 0128:B12) LPS. Results: …

Aim: The aim of the present study was to investigate the survival time of some nosocomial infectious agents on the surface of various covering materials. Materials and Methods: Four kinds of flooring materials (vinyl and ceramic tile as floor covering material; and laminate and inox sheet as bench covering material) were experimentally contaminated with Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus and vancomycin-resistant (VR) Enterococcus faecalis, which were frequently encountered in nosocomial infections. The survival periods of representative agents on the tested flooring materials were detected by culturing from the surfaces. Results: It was found that the survival periods were shorter …

Aim: Urinary tract infections (UTIs) caused in particular by extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli strains are related with high morbidity and mortality, and treatment is quite difficult. These infections generally are treated by carbapenems, and their costs are high. We aimed in this study to investigate the susceptibilities of ESBL-producing E. coli strains isolated from urine cultures to fosfomycin, ciprofloxacin, amikacin and trimethoprim-sulfamethoxazole and to determine the general resistance profile in our region of these strains isolated from UTIs. Materials and Methods: Between January 2005-December 2005, ESBL-producing E. coli strains isolated from urine samples sent from various outpatient and inpatient …

Comparison Of Antibiotic Resistance Patterns Of Uropathogenic Escherichia Coli In Outpatient And Inpatient Populations From 1990 To 1996 In Bemidji, Mn, Gail R. Conway, Patrick Guilfoile
Journal of the Minnesota Academy of Science
A retrospective study of antibiotic susceptibility was conducted on data from all uropathogenic Escherichia coli submitted to the MeritCare Clinic-Bemidji, MN and the North Country Regional Hospital-Bemidji, MN during 1990, 1993, and 1996. The proportion of antibiotic resistant strains was generally equal or higher in E. coli isolates from community-acquired infections than with E. coli isolates from nosocomial infections. Comparison with antibiotic prescriptions during 1990, 1993, and 1996 provided no clear relation between antibiotics prescribed for outpatient urinary tract infections and the proportion of E. coli strains resistant to those antibiotics. This suggests that factors other than selection for resistance …

Colicin Production And Colicin Typing Of Uropathogenic Escherichia Coli, Ayli̇n İmren Çarikçi, Güner Coşar
Turkish Journal of Medical Sciences
Colicins are bactericidal macromolecules in protein structures and they are produced by some strains of Escherichia coli and Shigella, which are members of the Enterobacteriaceae. They have a bactericidal effect on the same species or closely related bacteria, but have no effect on the strains which produce them. In this study, 129 E. coli strains isolated from urine samples of patients in Izmir and Manisa were examined for colicin production, and the colicinogenic strains were examined for their colicin types by means of Horak specific indicator strains. Indicator strains were obtained from the National Type Culture Collection Hygiene and Epidemiology …
