Change of Hematological Effects and Plasma Ionic Composition in Walking Catfish, Clarias batrachus (Linnaeus) Exposed to Aeromonas hydrophila.

บทคัดย่อ

Hematological studies on catfish, Clarias batrachus (Linnaeus) were conducted by injecting the fish with Aeromonas hydrophila at 5.6 x 10¹¹, call ml-¹, while the 0.6 ml. control saline solution was applied for the control one. The results shoe that, the infected fish with A. hydrophila were significasing trend in hematocrit value at 95%. Hemoglobin concentration, total crythrocyte, counts and mean corpuseular hemoglobin concentration (MCHC) from the infected fish with 19.6 x 10¹¹ cells ml-¹, were significant lower than the control value. There no statistic different in total leucocyte counts, differential leucocyte (neutrophil, lymphocyte and thrombocyte) , plasma Na+ and K+ in vitro.
