Abstract

The hemolytic activity of five live isolates of Trichomonas gallinae was investigated. The isolates were subsequently tested against the erythrocytes of seven adult animal species. Each of the five isolates tested lysed all human blood groups, as well as rabbit, rat, chicken, horse, bovine, and sheep erythrocytes. No hemolysin released by the parasite could be detected. Our preliminary results suggest that the hemolytic activity is not due to the hemolysin release by T. gallinae or to a product of its metabolism. Pretreatment of live trichomonads with concanavalin A reduced levels of hemolysis by 40%.

摘要

对五株活跃的鸡三毛滴虫分离株的溶血活性进行了研究。随后对这些分离株针对七种成年动物物种的红细胞进行了测试。测试的五株分离株中的每一株都能溶解所有人类血型以及兔、大鼠、鸡、马、牛和羊的红细胞。未检测到该寄生虫释放的溶血素。我们的初步结果表明，溶血活性并非由于鸡三毛滴虫释放溶血素或其代谢产物所致。用伴刀豆球蛋白A对活的滴虫进行预处理可使溶血水平降低40%。
