Abstract
The present study was carried out on microbial investigation to screening of pathogenic microorganism of selected commercially important shrimp samples Parapenaeopsis stylifera (Milne-Edwards, 1837); Penaeus merguiensis (de Man, 1888) Penaeus japonicas (Spence Bate, 1888) Ganjampenaeopsis uncta (Alcock, 1905) and Penaeus indicus (Milne Edwards, 1837) collected from fishing harbour of Visakhapatnam, east coast of India. The study was performed during the period of April 2015 to March 2016. Selectively, five commercially important shrimp were used to evaluate the quality of samples in terms of microbial content, using Agar plate method, Total Bacterial Count (TBC), Total coliform counts (TCC) was performed. The TBC ranged from 1.82X102cfu/g to 3.23X102cfu/g and TCC was found in between 2.14X102 and 5.22X102 whereas the total coliform count was not exceeded the acceptable limit recommended by FAO. The highly pathogenic bacteria Salmonella sp., Vibrio sp., was found in the collected shrimp samples.
