Antigenic identity of Yersinia enterocolitica serotypes O:Tacoma and O21

Identification of pathogenic serotypes of Yersinia enterocolitica.

Yersinia enterocolitica.

Characteristics of the disease Infectious dose is 10–100 organisms Incubation period is 1⁄2–4 (usually 1–3) days; up to a week for S. dysenteriae 1 Illness: diarrhea with fever and nausea; sometimes toxemia, vomiting, cramps, and tenesmus; dysentery—blood and mucus in stools; may cause hemolytic uremic syndrome; most severe in infants; mild and asymptomatic infections occur Duration: 4–7 days; ...

Direct detection and isolation of plasmid-bearing virulent serotypes of Yersinia enterocolitica from various foods.

A procedure was developed for direct detection, isolation, and maintenance of plasmid-bearing virulent serotypes of Yersinia enterocolitica from different food sources. Plasmid-bearing virulent strains of Y. enterocolitica representing five serotypes were simultaneously detected and isolated from enriched swab samples of artificially contaminated pork chops, ground pork, cheese, and zucchini, u...

Phenotypic and genotypic analysis of bio-serotypes of Yersinia enterocolitica from various sources in Brazil.

INTRODUCTION Yersinia enterocolitica is a well-known foodborne pathogen widely distributed in nature with high public health relevance, especially in Europe. METHODOLOGY This study aimed to analyze the pathogenic potential of Y. enterocolitica isolated strains from human, animal, food, and environmental sources and from different regions of Brazil by detecting virulence genes inv, ail, ystA, ...

Analysis of occurrence of virulence genes among Yersinia enterocolitica isolates belonging to different biotypes and serotypes.

The 150 Y enterocolitica strains isolated from humans and from pigs belonged to biotypes 4 (68.7%), 1A (18.7%) and 2 (4%), or were biochemically untypeable (8.6%). Biotype 4 was comprised of Y. enterocolitica strains representing serotype O:3, within biotype 1A the strains either belonged to serotypes O:5 and O:6 or were untypeable, and biotype 2 was represented by the strains of serotype O:9. ...
