Abstract: | A time course study on the endotoxin toxicity of the gram negative bacteria, Pseudomonas aeruginosa MTCC 1688 on the tissue phosphatases activity on the giant freshwater prawn, Macrobrachium rosenbergii was conducted. The results revealed marked elevation of both acid and alkaline phosphatase activity in the haemolymph and body muscle. The hepatopancreas showed reduced phosphatase activity compared to control. The enzymes, being non-specific in action and particularly the acid phosphatase being of lysosomal origin, their increase in muscle and haemolymph has pathogenic significance in the inoculum treated prawns. |
