Manifestations Studies on Enzyme Profile of Vibrio parahaemolyticus MTCC451 Inoculated Black Tiger Prawn Penaeus monodon

摘要

Vibriosis is one of the major pathogenic bacteria l diseases in shrimp aquaculture. Since, the disease patterns differ and the causes of the diseases are multifactorial, the results of such diagnostic profile tests could be correlated to the differing patterns of the disease. The present study aimed to evaluate the metabolic profile (biochemical and enzymatic) of V. parahaemolyticus MTCC 451inoculated black tiger prawn P. monodon (Fabricius). The injected V. parahaemolyticus MTCC451 resulted in the outbreak of vibriosis in the tested P. monodon. The levels of Alkaline phosphatase activity, Acid phosphatase activity, Lactate dehydrogenase activity, Glutamate Pyruvate Transaminase (GPT) activity, Glutamate Oxaloacetate Transaminase activity, Chitinase activity, Water content, Sodium, Potassium, Calcium, Ascorbic acid and Histamine in Haemolymph, Hepatopancreas and Body muscle of P. monodon control Vs tested were noted. The laboratory results of the present investigation, using the inoculum Vibrio parahaemolyticus MTCC451 revealed that these endemic bacterial populations might become opportunistic pathogens, when hydroecological conditions are altered in the farm ponds and could bring the fatal episodes of mass mortality.
