Abstract

Biochemical and biological properties of in vivo and in vitro hemolysins of cholera germs isolated by different authors as well as hemolysins of Vibrio parahaemolyticus and Escherichia coli have been comparatively characterized. According to the above data hemolysin of cholera germ El Tor is a thermolabile protein with molecular mass of 60-80 thou.; it is cytotoxic, enteropathogenic and lyses all the species of erythrocytes. Hemolysins of V. eltor and germs are immunologically related. Hemolysin of the cholera germ is thermostable and has molecular mass of 20-40 thou., that makes it similar to hemolysin of V. parahaemolyticus.

[霍乱弧菌溶血素的比较特点]。
比较研究了不同作者分离的霍乱菌体内和体外溶血素以及副溶血弧菌和大肠杆菌溶血素的生化生物学特性。根据上述资料,霍乱病菌El - Tor溶血素是一种分子质量为60-80 μ m的耐热性蛋白;它具有细胞毒性,肠致病性,并能溶解所有种类的红细胞。溶血素与细菌有免疫学关系。霍乱病菌的溶血素是耐热的,分子质量为20- 40kg。这使得它与副溶血性弧菌的溶血素相似。
