[Atypical course of infections with enteritis salmonellas].

During the six-year period from 1978-1983 968 so-called "enteritis Salmonellae" were isolated in our laboratory. 50 of them (= 5,2%) were primary isolations from extraintestinal specimens, first of all from blood, abscess smear and urine. The greater part of the patients with an atypical course of enteritis salmonellosis showed clinical signs of septicemia (44%) or local suppuration (24%). In atypical salmonellosis advanced age and sex distinctly prevailed compared to the distribution of age and sex of patients suffering from typical Salmonellae enteritis. 80% of the patients with atypical salmonellosis had mostly resistance lowering basic diseases, first of all diabetes mellitus, or were treated with immunosuppressive therapy. The spectrum of "enteritis Salmonellae" isolated only from feces during the same period differed significantly (p = 0,01) from the spectrum of Salmonellae types found in extraintestinal specimens. An atypical course was relatively often caused by S. enteritidis, S. panama and S. virchow.
