[Serological typing of Vibrios, nonagglutinating with O-cholera serum, isolated in USSR].

The authors carried out serological typing of 2008 strains of NAG vibrios isolated in 1968--1975 in 18 territories of the Soviet Union from humans and from the objects of environment. Serological type was established in 40.5% of the srains isolated from humans and in 16% of the strains obtained from the environmental objects. Among persons with acute gastrointestinal diseases serotype 5 was the one which dominated, and among strains from the environment--serotype 8 Sakazaki. Serological type 15 was revealed for the first time in the USSR at the territory of Siberia and the Far East among the NAG-vibrio strains isolated from the environment.
