title: [Comparative effectiveness of the bacteriologic method and of the direct determination of the O antigen of the causative agent in research on the excretions of patients with salmonellosis due to Salmonella typhimurium].
abstract: The diagnostic effectiveness of the direct determination of Salmonella O-antigen in different excretions of patients with S. typhimurium infection and other acute intestinal diseases has been studied. According to the occurrence of the antigen in different kinds of excretions, they are arranged in the descending order as follows: feces, urine, saliva. The parallel serological and bacteriological study of feces enhances the number of positive results 1.6 to 2.4 times in comparison with the bacteriological study alone. The occurrence of the antigen in excretions does not depend on the age of the patients and on the severity of the disease. The indication of Salmonella O-antigen may serve as an effective supplement to bacteriological study.
