摘要

从有腹泻症状的儿童粪便中分离出的20株鱼穴气蛾检测了其毒力相关特性:产生细胞毒性和细胞滋补性毒素，以及侵袭能力。大部分菌株对Vero和CHO细胞具有细胞毒性，并产生细胞滋补毒素，使CHO细胞伸长。此外，5株蛇麻杆菌对HEp-2细胞具有侵袭能力。

Enteropathogenic activity and invasion of HEp-2 cells by Aeromonas caviae clinical isolates.

Twenty Aeromons caviae isolates from stool of children with diarrhea symptoms were examined for virulence-associated properties: production of cytotoxic and cytotonic toxins, and invasive ability. Most of A. caviae strains were cytotoxic to Vero and CHO cells and produced cytotonic toxins which caused elongation of CHO cells. Moreover, five of A. caviae strains revealed invasive ability towards HEp-2 cells.
