A virulent strain of Y. enterocolitica isolated from slaughter pigs was used to infect mice BALB/c. A dose of 10s given orally caused a heavy infection in all the mice. The bacteria administered subcutaneously resulted in the signs of septicaemia and death. The PM lesions in various tissues were similar: granulomas containing neutrophiles and histiocytes and micro-purulent foci produced the picture of micro-abscesses. The findings indicate that virulent strains of Y. enterocolitica isolated from pigs produce a similar process of disease as human strains do It seems that pigs are a natural reservoir of virulent strains of Y. enterocolitica and constitute a potential source of infection.
