Isolation of Yersinia group in human infections, animals and environment factors.

Abstract

The presence of Y. enterocolitica and Y. pseudotuberculosis was studied in 4479 enteritis cases, 430 children, presenting appendicular syndrome, and 60 hospitalized patients with arthritis and Reiter syndrome. Y. enteritis was detected in 41 (0.9%) enteritis cases, 15 (3.4%) appendectomized children and 5 (8.3%) arthritis cases. Antibodies to Y. pseudotuberculosis were detected in 2 (3.3%) arthritis patients. Y. enterocolitica was isolated in swine, fish and environment factors (water, soil, food). Y. pseudotuberculosis was isolated in soil. The isolated strains belonged to biotypes 1, 2, 4 and serotypes 0:3; 0:5; 0:5.27; 0:5, 6, 7, 8; 0:6; 0:9; some were non-typable and polyagglutinable. The strains were sensitive to bacteriophages for Yersinia, obtained in our laboratory.
