title: [Significance of an increase in the titer of agglutinins in the microagglutination test in leptospirosis].
abstract: The authors considered different views of investigators on the diagnostic antibody titre level in the microagglutination test (MAT) in leptospirosis of man and animals. Some of them took into consideration MAT in low titres (1:10-1:20), and others - in high only (1:400, 1:1000), which gave no possibility to assess the state of leptospirosis morbidity. The authors suggest that the assessment of the level of the titres in single and repeated studies should be approached differentially. In single examination 1:100 and over should be considered as a positive MAT titre for man, 1:200 and over - for cattle, 1:20 and over - for swine, and 1:20 and over for murine rodents. In repeated investigations any level of the titre in case of its dynamics should be taken into consideration.
