in this study 130 bulk tank milk samples which were delivered to the pegah pasturisation factory inmashhad were collected randomly during the summer months. samples were firstly enriched in modifiedtrypticase soy broth containing novobiocin, followed by plating onto sorbitol macconkey agar supplementedwith cefixime and potassium tellurite for isolation of escherichia coli o157:h7. consequently ...
Antibiotic resistance occurs in the endogenous flora of exposed population in addition to pathogenic bacteria. This study was conducted to evaluate the distribution of antibiotic resistance genes among 63 isolates of Escherichia coli of Escherichia coli (E. coli) in diarrheic calves and poultry. According to the results, B1 and B2 were the most prevalent phylogroups of E. coli in calves and pou...

The aims of the current study were to detect the virulence factors and antibiotic resistance of Shiga toxin-producing E. coli, in animal milk and dairy products in Iran. After E. coli dentification with culture method, PCR assay were developed for detection of pathogenic genes, serotypes and antibiotic resistance genes of E. coli. Results showed that out of 719 samples, 102 (14.18%) were confir...
background: urinary tract infection (uti) is one of the most prevalent infectious diseases and escherichia coli is its common cause. the aim of this study was to assess the resistance patterns of e.coli in urinary tract infections and to determine the susceptibility of e.coli to commonly used antimicrobials and also to evaluate the options for empirical treatment of uti. methods: this study was...
Introduction & Objective: Diarrheal diseases are considered a major health problem, especially in children. Enteropathogenic Escherichia coli (EPEC) strains are the common cause of diarrhea in children especially in developing countries. Because of undesirable effects of diarrhea and its interference with children's growth, in some cases antibiotic treatment is recommended. In recent years, r...

Background and Objective: Bacterial agents are the most common causes of urinary infection with Escherichia coli as the major causative organism. Accordingly, the current study aimed to determine the antibiotic resistance among Escherichia coli isolates from human urinary infection cases. Materials and Methods: The current experimental study was carried out on 50 specimens of positive cultures...
background and objectives: β-lactamase production is the predominant mechanism for resistance to β-lactams in enterobacteriaceae. the producing isolates are often multidrug resistant and are major hosts for extended spectrum β-lactamases. this study was designed to determine the prevalence of extended-spectrum β-lactamase producing isolates of escherichia coli and klebsiella pneumoniae and thei...
Abstract Background Gastroenteritis is a common infectious disease in children, which results high mortality and morbidity, especially resource-poor countries. This study presents the selected main gastroenteritis causing bacteria, including Escherichia coli O157, Salmonella Shigella species delineating their prevalence resistance pattern to clinically used antibiotics. Results A total of 346 s...
