[Toxigenicity of NAG-vibrio isolated from patients and disease carriers].

The article deals with the in vitro determination of toxigenicity in 311 NAG vibrio strains isolated from patients with acute intestinal diseases and from healthy persons. Enterotoxin-synthesizing strains have been found to occur among NAG vibrios isolated from patients as frequently as among strains from healthy persons. The latter ones have also proved to be weaker as toxin producers. Comparative determination of virulence and toxigenicity in 54 NAG vibrio strains has demonstrated a significant prevalence of cultures with weak virulence over those with weak toxigenicity.

[El Tor vibrios with different enteropathogenicities].

The authors summed up the results of study of enteropathogenicity of 270 strains of the El Tor vibrios isolated the last 11 years. Over 2 000 nursling rabbits were used. El Tor vibrios were divided by their enteropathogenic properties into three categories: 1) the highly enteropathogenic (cholerogenic) ones causing the death of all the biotest nursling rabbits with a characteristic syndrome of cholerogenicity, and failing to lyse sheep erythrocytes; 2) enteropathogenic ones, causing death of some of the biotest animals without any characteristic cholerogenicity syndrome, but with the intestinal lesions; strains of this category are hemolytic; 3) nonenteropathogenic, causing no death of the animals even when their high doses are administered; these bibrios are hemolytic (cause lysis of sheep red blood cells).
