Immune response of catla catla fed with an oral immunostimulant plumbago rosea and postchallenged with aeromonas hydrophila.

ABSTRACT

The present study was designed to evaluate the immunostimulant potential of Plumbago rosea in fish catla, post challenged with Aeromonas hydrophila. Fishes were divided into 2 groups one received control diet and another received Plumbago rosea incorporated diet for 14 days. The haematological parameters and serum protein were estimated between control and experiment. There is An increase in TEC (P<0.05) and TLC (P<0.05) in the immunostimulant administered (IS)diet was observed. Increase in lymphocyte count was noted in immunostimulant incorporated diet. Remarkable increase in Hb from 6.2 to 8g% and serum protein level from 0.4to 0.5g% was observed in experimental fishes The immunostimulant administered Catla catla when challenged with Aeromonas hydrophila showed a decrease in TEC and an increase in TLC. Increase in lymphocytes was also noted.
