Haemolysin production of 1,103 strains of Enterobacteriaceae was investigated on trypticase soja agar containing washed horse erythrocytes. Nearly all haemolytic strains belonged to the genus Escherichia (103 haemolytic strains out of 349 examined). The 3 remaining haemolytic strains belonged to the genus Serratia (of which 244 strains were examined). Plasmidic determinism of haemolysis was demonstrated for six of the Hly+ E. coli strains, and these plasmids were transferred to E. coli K12, Salmonella typhia and S. typhi-murium. Investigations about coexistence of four of these plasmids with "metabolic" plasmids and with representatives of the plasmids compatibility groups presently known, showed that two of these plasmids were fi+ and belonged to the FIII group, and that two other were fi- and related to the I2 group. Thus, different plasmids can determine haemolysin-production in E. coli strains.
在含有洗涤过的马红细胞的胰蛋白酶大豆琼脂上，对1103株肠杆菌科细菌的溶血素产生情况进行了研究。几乎所有溶血菌株都属于埃希氏菌属（在349株检测菌株中有103株溶血菌株）。其余3株溶血菌株属于沙雷氏菌属（检测了其中244株）。对6株溶血阳性的大肠杆菌菌株证明了溶血的质粒决定性，并且这些质粒被转移到大肠杆菌K12、伤寒沙门氏菌和鼠伤寒沙门氏菌中。对其中4种质粒与“代谢”质粒以及目前已知的质粒相容性组代表共存情况的研究表明，其中两种质粒是fi + ，属于FIII组，另外两种是fi - ，与I2组相关。因此，不同的质粒可以决定大肠杆菌菌株中溶血素的产生。
