title: [Methods of using the antibody neutralization test in intestinal coli-infections].
abstract: Specificity and sensitivity of the antibody neutralization test intended for detection of the O-antigen of enteropathogenic escherichia were checked under experimental conditions. Only 3 strains of the Klebsiella genus proved to neutralize the antibodies to the enteropathogenic escherichia of the serological group O20:K84. In the rest of the cases a positive result was obtained only in homologous combinations. In comparative study of the microbial cultures of the infected feces on hard nutrient media by means of bacteriological and serological methods the latter was found to be more sensitive, capable of detecting the homologous O-antigen with the bacterial concentration of not less than 5-10(5) microbial cells per 1 ml.
