Isolates (49) of escherichia coli were isolated from 100 samples of mutton collected from dressed sheep carcasses by excision method. The isolates were typed into 12 different ‘O’ serogroups. The most frequent serovar isolated was O101, followed by O152, O76, O23, O139, O88, O110, O126, O8, O9, O15 and O133; two isolates were untypable while one was rough. All the isolates of escherichia coli w...

to determine the contamination of traditional cheeses to e. coli o157:h7 this study was conducted in chaharmahal and bakhtiari province. two hundred cheeses samples were obtained randomly and bacteriological examinations were done on all isolates, by culture in selective enrichment media and after that, selective plating. suspected colonies were examined with o and h antisera for identification...

The scope of this study was to characterize the intra-serotypic genetic diversity in fecal Escherichia coli isolates obtained from dogs, using enterobacterial repetitive intergenic consensus (ERIC)-PCR. Serological typing of forty-seven E. coli isolates recovered from the rectal swabs (n=93) of different dog breeds in Andhra Pradesh revealed O141 (5 isolates), O128 (3 isolates), O126 (2 isolate...

Deformities of cranial sutures such as craniosynostosis and enlarged parietal foramina greatly impact human development and quality of life. Here we have examined the role of the extracellular matrix protein ameloblastin (Ambn), a recent addition to the family of non-collagenous extracellular bone matrix proteins, in craniofacial bone development and suture formation. Using RT-PCR, western blot...

The main objective of this study was to investigate the epidemiology, drug resistance and β-lactamase genotype distribution of enteropathogenic Escherichia coli (EPEC) isolated from pediatric patients with diarrhea in southern China. The prevalence of EPEC in children with diarrhea was 3.53%. The commonest serotypes were O55:K59 and O126:K71, and the typical EPEC were more prevalent than atypic...

We have investigated 37 minor serogroup Shiga toxin-producing Escherichia coli (STEC) strains other than O157, O26, and O111 isolated from human specimens in Osaka prefecture to determine their serological and biochemical characteristics, virulence-associated genes, and clinical signs in patients. The same serotype strains were genotyped by pulsed-field gel electrophoresis (PFGE). The O antigen...

Fifty-five Escherichia coli strains belonging to enteropathogenic E. coli (EPEC) serogroups were examined for phenotypic and genetic factors associated with virulence. The strains were isolated in Italy from children with diarrhea and identified as EPEC by clinical laboratories using commercially available antisera. O:H serotyping showed that 35 strains (27 of O26, O111, and O128 serogroups) be...

BACKGROUND Enteroaggregative Escherichia coli (EAEC) are a heterogeneous category of emerging pathogens associated with acute and persistent diarrhea. METHODS We performed a case-control study to evaluate the association of EAEC strains and their virulence markers with infantile diarrhea in Brasilia, Brazil. RESULTS Of the EAEC markers that were tested, only EAEC heat-stable toxin (EAST1), ...
