Yersinia enterocolitica as a causative agent of septicaemia

The authors describe the first case of isolation of Yersinia enterocolitica from blood in a septic infection in Czechoslovakia. They also isolated a strain of Y. enterocolitica from an inguinal tumour in the same patient. Both strains belonged to biotype 4, serotype 0:3 and phagotype 8 and were non-pathogenic for guinea pigs and hares.
