Abstract :A haematological study was carried out with rainbow trouts experimentally infected with Yersinia ruckeri. One hundred rainbow trouts insert ignore into journalissuearticles values( Oncorhynchus mykiss); at 192±0.24 g were examined. Yersinia ruckeriat a concentration of 3x10 6 cfu/0.1 ml was intraperitoneally insert ignore into journalissuearticles values(i.p.); injected to 50 animals. The blood samples of infected and control groups were collected from caudal vein in 1, 2, 3, 4, 5, 7, 9, 11, 13 and 15 days after inoculation. Some haematological parameters: erythrocyte, leucocyte and thrombocyte counts; differential leucocyte types; haematocrit; mean cell volume insert ignore into journalissuearticles values(MCV);, mean cell haemoglobin insert ignore into journalissuearticles values(MCH);, mean cell haemoglobin concentrations insert ignore into journalissuearticles values(MCHC);; haemoglobin, plasma total protein and albumin concentrations were determined. Differences in percent of leucocyte types insert ignore into journalissuearticles values(increases in monocyte and small lytmphocyte, a decrease in large lymphocyte were not seen. From red blood cell indices insert ignore into journalissuearticles values(MCV, MCH, MCHC); parameters of MCV values markedly variation were determined only at 3.13 and 15 days.
