The aim of this study was to determine antibiotic resistance genes, phylogenetic groups and anti-microbial resistance patterns of Escherichia coli isolates from fecal samples of healthy pet cats in Kerman city. Ninety E. coli isolates were recovered from obtained rectal swabs. Antibiotic resistance pattern of the isolates against seven selected antibiotic was determined using disc diffusion met...

Esta investigación tuvo por objetivo la caracterización bioquímica y identificación de filogrupos en cepas Escherichia coli, heces terneros con diarrea, mediante el método Clermont. Se recogieron treinta dos muestras ocho rebaños del caserío Tartar Grande, distrito Baños Inca, región Cajamarca, Perú. Mediante crecimiento agar MacConkey-MUG fueron seleccionadas trece caracterizándose bioquímicam...

In this study, 200 Escherichia coli isolates from 22 rainwater tank samples in Southeast Queensland, Australia, were tested for the presence of 20 virulence genes (VGs) associated with intestinal and extraintestinal pathotypes. In addition, E. coli isolates were also classified into phylogenetic groups based on the detection of the chuA, yjaA, and TSPE4.C2 genes. Of the 22 rainwater tanks, 8 (3...

Atypical enteropathogenic Escherichia coli (aEPEC) strains are emerging enteropathogens that have been detected worldwide. A collection of 228 aEPEC strains (121 from diarrheal patients, 27 from healthy carriers, 47 from animals and 33 from raw meats) were investigated for serotypes, virulence gene profiles and phylogenetic relationships. Sixty-six O serogroups were identified. Serogroup O51 wa...

زمینه و هدف: کم‌تحرکی در مقابل آن تمرین جزء عوامل مرتبط با شاخص‌های آسیب کبدی به‌شمار می‌روند. وجود این هنوز نقش بسیاری از تمرین‌های ورزشی به‌ویژه تمرینات تناوبی مقاومتی مصرف برخی مکمل‌های غذایی جمله اسپیرولینا بر ایمنی التهابی کاملاٌ شناخته نشده است؛ بنابراین هدف پژوهش تعیین اثر هشت هفته مکمل‌دهی هوازی فعالیت بافت کبد بیان ژن CXCL1 عضلة موش‌های صحرایی نر بود.مواد روش‌ها: نیمه‌تجربی، 60 سر موش ن...

BACKGROUND Clinical isolates of herb-resistant uropathogenic E. coli were isolated. It was possible that the virulence genotypes and phylogenetic background of E. coli differed between Chinese herb-resistant E. coli and -susceptible isolates. For this purpose, the prevalence of virulence factors (VFs) and phylogenetic background, with regard to Chinese herb resistance, among E. coli strains cau...

Background: Segregation of Escherichia coli (E. coli) into the phylogenetic groups was observed in experiments so that group B2 contained enteropathogenic E. (EPEC) strains and extraintestinal pathogenic (ExPEC). Objectives: This study aimed to identify extended-spectrum Cephalosporins resistant isolated from stool healthy children under 10 years old. Methods: One hundred broad-spectrum were co...
