Three cases of neonatal meningitis, two of which were fatal, occurred in a premature baby unit during a period of one week. A fourth case occurred in the same unit six months later. Citrobacter koseri was isolated from the cerebrospinal fluid of all four cases. Detailed biochemical and serological examination of the organisms showed that two distinct bioserotypes were involved.

Tonsils of 829 fattening pigs originating from Belgium (n = 201), Italy (n = 428), and Spain (n = 200) were collected between 2005 and 2007 to study the prevalence of enteropathogenic Yersinia in slaughter pigs. Isolation of Yersinia enterocolitica and Yersinia pseudotuberculosis was done by selective enrichment and by cold enrichment for 7 and 14 days. Pathogenic Y. enterocolitica and Y. pseud...

The aim of this study was to determine the prevalence of Yersinia enterocolitica and its bioserotypes from food and pigs in Malaysia. Fifty-eight raw porcine (raw pork meat, internal organs and other parts) and 48 non-porcine food (raw beef, poultry products, seafood, vegetables, tofu, and pasteurised milk) from wet markets located in Kuala Lumpur, Selangor, Perak, and Pahang were examined for ...

Yersinia enterocolitica is a food-borne pathogen that causes gastroenteritis with occasional postinfection sequels. This study was aimed to determinate the pathogenic potential, antimicrobial susceptibility, and genomic relationships of Y. enterocolitica strains of different bioserotypes (B/O) isolated from foods and human samples in San Luis, Argentina. Strains obtained by culture were biosero...

Yersinia enterocolitica and Yersinia pseudotuberculosis, the two Yersinia species that are enteropathogenic for humans, are distributed worldwide and frequently cause diarrhea in inhabitants of temperate and cold countries. Y. enterocolitica is a major cause of foodborne disease resulting from consumption of contaminated pork meat and is further associated with substantial economic cost. Howeve...

Yersiniosis is strongly associated with the consumption of pork contaminated with enteropathogenic Yersinia enterocolitica, which is harbored by domestic pigs without showing clinical signs of disease. In contrast to data on Y. enterocolitica isolated from conventionally reared swine, investigations into the occurrence of Y. enterocolitica in wild boars in Germany are rare. The objectives of th...

Yersinia enterocolitica is a common food-borne pathogen involved in yersiniosis among humans. The present study aimed to isolate virulent Y. enterocolitica from small ruminant milk in Shahrekord, Iran. One hundred raw milk samples of 84 sheep and 16 goats were collected from different parts of Shahrekord, during fall 2015. The samples were studied by microbial method and the positive-culture sa...

The predominant bioserotypes of pathogenic Yersinia enterocolitica in China are 2/O: 9 and 3/O: 3; no pathogenic O: 8 strains have been found to date. Multiple-Locus Variable-Number Tandem-Repeat Analysis (MLVA) based on seven loci was able to distinguish 104 genotypes among 218 pathogenic Y. enterocolitica isolates in China and from abroad, showing a high resolution. The major pathogenic serog...

Background:Yersinia is a genus in the family Enterobacteriaceae that its species includeYersinia enterocolitica, Yersinia intermedia, Yersinia frederiksenii, and Yersinia kristensenii. Among these species, Yersinia enterocolitica is the most important one that causes various diseases such as gastroenteritis, mesenteric lymph...
