Yersinia enterocolitica biogroup 1A, serotype O:5 in chicken carcasses
To evaluate the presence of Yersinia enterocolitica in raw chicken, 70 samples of chicken carcasses were obtained from a Buenos Aires, Argentina, processing plant. The detection of this psychotropic microorganism was carried out using the whole carcass rinse method and enrichment in phosphate-buffer...
