Caprine enteritis associated with Yersinia pseudotuberculosis infection.
Yersiniosis was prevalent among a caprine herd during the late autumn of 2003 in Iwate Prefecture, Japan. The disease affected 29 of about 100 lactating goats, but not dried or nonparous goats, mature male goats or kids. Four animals died within an epidemic period of 20 days. Affected animals developed decreased milk production with subsequent watery diarrhea, neutrophilia with increased band f...
متن کاملCharacteristics of Yersinia pseudotuberculosis isolated from animals in Brazil.
Strains (105) of Yersinia pseudotuberculosis isolated in Brazil between 1982 and 1990 were bio-serotyped. They were also studied for plasmid profile, autoagglutination and calcium dependence at 37 degrees C, Congo red uptake, pyrazinamidase activity, esculin hydrolysis, salicin fermentation and drug sensitivity: 95.24% were biotype 2, serogroup O:3; 2.86% were biotype 1, serogroup O:1; and 1.90...
متن کاملExperimental kinetics of infection induced by Yersinia pseudotuberculosis isolated from stock animals.
The course of in vivo infection of five isolates of Yersinia pseudotuberculosis was followed for three weeks in Swiss mice. The strains were isolated from diarrheic and normal feces and mesenteric lymph nodes of healthy and sick stock animals. Four strains of serogroup O:3 and one of serogroup O:1a, with and without the virulence plasmid, were inoculated intragastrically and intravenously in th...
متن کاملYersinia pseudotuberculosis and arthritis.
In 1986 and 1987 nine patients with a raised antibody titre to Yersinia pseudotuberculosis were found. Two of these results were almost certainly due to the cross reactivity between some Y pseudotuberculosis serogroups and some salmonella serotypes. Of the other seven patients with otherwise unexplained Y pseudotuberculosis serology, three suffered from severe arthritis and two had symptoms sug...
متن کاملInvasin expression in Yersinia pseudotuberculosis.
A 3.2-kb region on the chromosome of Yersinia pseudotuberculosis, called inv, encodes invasin, a 103-kDa protein of the bacterial outer membrane. Invasin mediates bacterial entry into cultured animal cells. Six Y. pseudotuberculosis strains isolated from animal or human infections were analyzed for the presence of inv-related sequences with a radiolabeled inv clone, pRI203. We found that inv-sp...
