Pseudomonad Infection in Channa Causes Changes in Behavior, Growth and Hematological Parameters with Reference to its Control by Plant Extract

The present study was carried out to investigate the pathogenecity of Pseudomonas in freshwater fish, Channa punctata (Bloch 1793). Each fish excepting from control-I was intraperitoneally injected with 0.2 ml of the experimental bacterium (Pseudomona aeruginosa) (Treatment : T1, T2, T3, T4, T5 and...

Summary:The present study was carried out to investigate the pathogenecity of Pseudomonas in freshwater fish, Channa punctata (Bloch 1793). Each fish excepting from control-I was intraperitoneally injected with 0.2 ml of the experimental bacterium (Pseudomona aeruginosa) (Treatment : T1, T2, T3, T4, T5 and T6) and control-II fish was injected with 0.2 ml of agar broth without bacterium, using 21/gauge sterile needle. Behavioral changes, growth parameters, blood parameters and histopathological changes have also been observed in the experimental fishes. Decrease in length and weight loss of infected fish is common features. Antagonistic activity of the plant extract mixture of Allium sativum and Piper nigrum against P. aeruginosa confirmed by restoration of normal behavior, growth rate (P > 0.05), normalization of physiological and biochemical changes of the fishes.
