aim : we intended to find out the diversity of epec isolates among asymptomatic or diarrheal children in iran using ribotyping. background : enteropathogenic escherichia coli (epec) is responsible for gastroenteritis especially in young children. patients and methods : a total of 39 epec collected strains were serotyped and the presence of virulence genes as well as eaf plasmid among the strain...

a total of 610 strains of shigellae isolated from cases of diarrhea in iran during 1962-73 were studied with respect to their phage type, as well as antibiotic resistance and transferable drug resistance along with serotyping. it was shown that there was some relation between serotypes and phage types but no association could be found between phage types and resistance pattern.

Infectious gastroenteritis is one of the most common diseases in young children. To clarify the infectious etiology of diarrhea in Danish children less than 5 years of age, we conducted a 2-year prospective case-control study. Stools from 424 children with diarrhea and 870 asymptomatic age-matched controls were examined, and their parents were interviewed concerning symptoms. Rotavirus, adenovi...

Serotyping of porcine rotaviruses isolated in MA104 cells from Australian piglets with diarrhea showed that two strains belonged to serotype 3 and one strain was antigenically similar to the OSU strain of porcine rotavirus (serotype 5). In addition, neutralizing antibodies to human rotavirus serotype 4 (ST-3 strain) were detected in serum samples from sows in one area, and so it seems probable ...

Introduction: Awareness of the species of Shigella has particular importance in the way of dealing with an outbreak, controlling it, and treating patients. The purpose of this study was to use the Multiplex PCR method and comparison with the culture method to detect Shigella species, as well as analysing the antibiotic resistance pattern in its different species. Methods: Simultaneously, the fe...

Enterotoxigenic Escherichia coli (ETEC) is a major cause of diarrhoea in children below 5 years of age in endemic areas, and is a primary cause of diarrhoea in travellers visiting developing countries. Epidemiological analysis of E. coli pathovars is traditionally carried out based on the results of serotyping. However, genomic analysis of a global ETEC collection of 362 isolates taken from pat...

Ten out of 18 babies at risk developed enteritis in an outbreak in a special-care baby unit. Salmonella, Shigella, and Escherichia colibelonging to the traditional infantile enteropathogenic serogroups were not found in faeces from the babies and the staff, and no virus particles were found by electron microscopy. Detailed serotyping of E. coli showed that five of the 10 babies with diarrhoea a...

Fifty-eight Compylobacter strains were isolated from children with diarrhoea at various health centres in Lagos and from healthy chicken. Twenty-nine strains of Campylobacter were isolated from humans, while the same number were isolated from chicken. The strains were biotyped using the modified Preston biotype scheme. The Preston biotyping results have been compared with the results of Penner ...
