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...

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...

Escherichia coli strains of serotype O51:H40 were studied with regard to the presence of several virulence properties and their genetic diversity and enteropathogenicity in rabbit ileal loops. This serotype encompasses potential enteropathogenic strains mostly classified as being atypical enteropathogenic E. coli (EPEC) strains, which are genetically closer to enterohemorrhagic E. coli than to ...

Objective(s) Extensive use of quinolones has been associated with raising level of resistance. In the current, we focused on assessing the prevalence of Escherichia coli resistance to quinolones and frequency of qnrA, qnrB and qnrS in non ESBLs (extended spectrum beta-lactamases) and ESBLs producing E. coli with blaSHV and blaTEM. Materials and Methods One hundred and fifty E. coli isolates ...

colibacillosis caused by avian pathogenic escherichia coli (apec) is an economic threat to the poultry industry throughout the world. some of the virulence genes may enhance the ability of e. coli isolates to grow in the tissues of broilers. the apec strains are assigned to a few distinct phylogenetic groups. the purpose of the present study was to detect the virulence genes and phylogenetic gr...
