[Development of antilipase immunoglobulin polymer diagnosticum for the detection of Vibrio cholerae eltor, possessing hemolytic and lipase activity].

ABSTRACT

The possibility of using a heterogeneous, but structurally similar antigen--the commercial preparation of Pseudomonas sp. lipase (Sigma, USA)--for the development of polymer diagnosticum aimed at determination of lipase production in cholera vibrios was shown. The new diagnosticum (antilipase antibodies) on a polymer carrier was used in the serological volume agglomeration test for the detection of hemolytic atoxigenic V. eltor, obtained from environmental, objects, which produced lipase in 80% of cases. The differentiating capacity of the diagnosticum was confirmed on 120 V. eltor cultures isolated from environmental objects. The newly developed diagnosticum makes it possible to determine the lipase activity in cholera vibrios of different biovars and serovars.
