Abstract

A virulent strain of motile aeromonad (77-18) and an avirulent strain (78-16) differed in the contents of lipids and phospholipids, odd fatty acids, activity of hydrolytic enzymes, and amount of proteins with molecular weights of 47-56 kDa. It is assumed that proteins with molecular weights of 47-56 kDa, proteolytic enzymes active within a wide pH range, and odd fatty acids may act as pathogenicity factors. Each of these compounds or their combination determines certain stage of infection.

摘要

一株运动性气单胞菌的强毒株（77 - 18）和一株无毒株（78 - 16）在脂质和磷脂含量、奇数脂肪酸、水解酶活性以及分子量为47 - 56 kDa的蛋白质数量上存在差异。据推测，分子量为47 - 56 kDa的蛋白质、在较宽pH范围内具有活性的蛋白水解酶以及奇数脂肪酸可能作为致病因素。这些化合物中的每一种或它们的组合决定了感染的特定阶段。
