[Salmonellosis and concomitant yersiniosis].

Clinical description of salmonellosis and concomitant yersiniosis in 6 women aged 26-50 years infected from a common source is presented. They were members of a group of 65 women suffering alimentary intoxication the source of which was supposed to be either light-salted salmon or vegetable salad. The incubation period varied from 4 to 12 hours. The disease started as an acute infection with a rise in temperature to 38.5-40 degrees C, repeated vomiting, mucous-watery diarrhea and pain in the right half of the abdomen (largely in the ileocecal region). These symptoms provided a basis for differential diagnosis from yersiniosis and appendicitis. The patients presented with leukopenia and moderate leukocytasis with the prevalence of rod-nuclear cells (up to 9-56%). Diagnosis of mixed infection was confirmed by detection of group D1 S. enteriditis in feces and positive serological reactions with O3 intestinal-yersiniosis diagnosticum. Fever, diarrhea, and abdominal pain persisted for 5-6 days, The patients were treated by rehydration, symptomatic and antibacterial therapy (ciprofloxacin, cifran).
