Hemolytic activity of fresh isolates and clones of Trichomonas gallinae
In in vitro assay the hemolytic activity of live isolates and clones of Trichomonas gallinae was investigated. The fresh isolates and clones were tested against human erythrocytes of groups A, B, AB, and O, and against erythrocytes of six adult animals of different species (rabbit, rat, chicken, hor...
