the present work was conducted to compare the occurrence of escherichia coli possessing virulence and esbl genes in backyard and farmed poultry. three hundred and sixty samples from the poultry kept in backyard system and 120 samples from the farmed birds were collected from west bengal, india. among the e. coli isolates of backyard poultry (o2, o10, o25, o55, o60, o106, ut), none of them posse...

background: uropathogenic escherichia coli o- serogroups with their virulence factors are the most prevalent causes of utis. objectives: the present investigation was performed to study the virulence factors and o-serogroups profiles of upec isolated from iranian pediatric patients. patients and methods: this cross sectional investigation was performed on 100 urine samples collected from hospit...

penicillin acylase (ec 3.5.1.11) has been a target of study for a long time because of its pivotal role in the deacylation of the penicillin into the 6- aminopenicillanic acid (6-apa) and the side-chain organic acids. this property of penicillin acylase has been exploited commercially for large scale production of 6-apa, which is the key intermediate in the manufacture of semi-synthetic penicil...

background:the bacterial contamination of fertile eggs isthe most common cause of embryonic death in ostrich hatcheryunits leading to financial loss in ostrich industry. objectives:the aim of this research was to investigate the bacterialcontamination status, with emphasis on escherichia coli, ofostrich hatcheries and the antimicrobial resistance profile ofisolated escherichia coli. methods:ato...

Introduction:  The aim of the present study was to investigate the presence and the frequency of EAEC as etiologic agent of diarrhea in Shiraz. Enteroaggregative E. coli (EAEC) is increasingly recognized as a cause of often persistent diarrhoea in children and adults in both developing and developed countries, and have been identified as the cause of several outbreaks worldwide.   Materials and...

The present study was conducted to detect the occurrence, serotype, genotype, phylogenetic relationship and antimicrobial resistance pattern of STEC from healthy goats of West Bengal, India. From the 125 faecal samples collected from healthy goats, 245 isolates were identified as Escherichia coli. The E. coli harbouring any gene for Shiga toxins (stx1/stx2) was detected in 36 (14.7%) of the 245...

Introduction: Extended spectrum beta-lactamase (ESBL) producing Escherichia coli generate a major problem for clinical therapeutics and epidemiological study. The incidence of ESBL producing strains among clinical isolates has been steadily increasing during the past few years, and remains an important cause of failure of therapy with cephalosporins. The aim of this study was to determine the a...

Background: The development of bacteria that have been resistant to antibiotics can complicate the treatment process. Either causes antibiotic resistance is inappropriate use antibiotics. Gentamycin an aminoglycoside-derived which its role very significant for gram-negative bacteria. Repeated gentamycin cause changes effectiveness so non ESBL-Gentamycin susceptible Escherichia Coli will change ...

We analyzed the prevalence of diarrheagenic Escherichia coli (DEC) markers and common phenotypes in 2,164 E. coli isolates from 282 DEC-positive samples. Enteropathogenic E. coli (EPEC) and enteroaggregative E. coli (EAEC) were very diverse and were not correlated with diarrhea. Enterotoxigenic E. coli (ETEC) estA and enterohemorrhagic E. coli (EHEC) belonged to a few phenotypes and were signif...
