ABSTRACT
This paper describes the detection of virus by using polymerase chain reaction and histopathological changes occurred in WSBV infected post larvae of Penaeus monodon. The affected shrimp showed red coloured body exhibiting type II outbreak. In histopathology, hypertrophied nuclei and eosinophilic inclusions were observed
ABSTRACT
Various antibiotics belonging to beta lactum, Rifampicin, Tetracycline, Quinolone, Aminoglycoside and synthetic groups were selected against vibrio species viz. V.fluvialis, V. furnissi, and V. splendidus, isolated from the diseased Penaeus monodon. The study revealed that among 15 antibiotics used, 12 showed sensitivity against V. fluvialis. In Vibrio furnissi among 16 antibiotics tested, 11 showed sensitivity, among 21 antibiotics tested, against V. splendidus, showed sensitivity against 14 antibiotics. Various antibiotics tested, ciprofloxacin was found to be more effective against all the test organisms
