[Toxigenicity of NAG-vibrio isolated from patients and disease carriers]. / Toksigennost' NAG-vibrionov, izolirovannykh ot bol'nykh i nositelei.

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.
