[The nature, frequency, specificity and duration of the retention of changes in different parts of the gastrointestinal tract in yersiniosis].

400 patients with yersiniosis, shigellosis, salmonellosis and abdominal typhoid were examined clinically, roentgenologically and using various instrument techniques for changes in the stomach and intestine. Yersiniosis and abdominal typhoid were characterized by dyskinesia of the small intestine and ileotyphlitis, Flexner's shigellosis by catarrhal-hemorrhagic proctosigmoiditis, Sonne salmonellosis and shigellosis by enteritis. Terminal ileitis occurred more frequently in yersiniosis patients in recurrence. After yersiniosis the patients may retain (for 3-24 months) lesions of ileocecal intestine without or rare clinical symptoms and develop chronic disease similar to initial stage of Crohn' disease.
