[Infections caused by Yersinia enterocolitica: bacteriological, serological, epidemiological and immunological findings in 51 cases (author's transl)].

Within two years 51 infections caused by Yersinia enterocolitica were diagnosed by bacteriological and (or) serological tests (Yersinia enterocolitica Serovar 03 in 48, Serovar 09 in two and Serovar 04 in one). The latter was isolated from the discharge of a badly healing superinfected wound. In the other 50 there was feverish enteritis, in 12 with arthritic complaints. Of the latter 12 nine had the antigen HLA-B27. This investigation demonstrated a slight increase in cases during the cold months. Men were more frequently affected than women and 38 were older than 16 years. In-vitro sensitivity of the isolated Yersinia strains against various chemotherapeutic agents was also tested.
