Abstract

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.

摘要

本文研究了从急性肠道疾病患者和健康人身上分离出的311株NAG弧菌的体外产毒性测定。结果发现，从患者身上分离出的NAG弧菌中产肠毒素菌株的出现频率与从健康人身上分离出的菌株相同。后者作为毒素产生者也被证明较弱。对54株NAG弧菌的毒力和产毒性进行比较测定表明，毒力弱的培养物比产毒性弱的培养物明显更普遍。
