[Hemolytic activity of various strains and clones of Trichomonas vaginalis and Tritrichomonas suis].

Hemolytic activity of 7 isolates and 2 clones of Trichomonas vaginalis and 1 isolate and 2 clones of Tritrichomonas suis was determined using incubation with erythrocytes. T. vaginalis hemolyzed all human blood groups, and no correlation between pathogenicity and hemolytic activity was observed and no hemolysin released by the parasite could be detected. No hemolytic activity was observed with strains and clones of T. suis against erythrocytes from all blood groups and with swine erythrocytes.

Lysis of erythrocytes by Trichomonas gallinae.

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%.
