Seafood constitutes an important food component and a cheap source of protein in developing countries. Shrimps are prone to bacterial contamination in their environment and have been frequently implicated in Vibrio parahaemolyticus infection. Of the 121 Penaeus monodon collected from coastal beaches in Douala, 79(65.3%) were contaminated with Vibrio spp. Presumed Vibrio sp. were identified by s...

A study was undertaken to determine the most effective element among the commonly used antimicrobial agents, especially in the body muscle of black tiger shrimp (Penaeus monodon) and giant freshwater prawn (Macrobrachium rosenbergii) on the basis of different chemical interventions. Using 10 ppm calcium hypochlorite, the microbial load has been reduced more significantly (p>0.001) than trisodiu...

A systematic checklist of fish and shellfishes the Poonthura estuary, Kerala, India is provided including notes on their conservation status. This includes 66 finfish five shellfish, belonging to 17 orders, 35 families, 60 genera. Carangiformes richest order (11 species, eight genera, three families), representing 15.4% total diversity. Carangidae, most diverse family with nine representatives,...

We report here the genome sequence of Vibrio campbellii LB102, isolated from the broodstock rearing system of a shrimp hatchery in India. Sequence analysis revealed the presence of effector toxins of the type III (YopT, sharing 39% identity with Yersinia pestis) and type VI (VgrG-3 and hemolysin coregulated protein of V. cholerae) secretion systems.

The beneficial effects of probiotics have been attributed to their ability to promote the immunological and nonimmunological defense barrier in the gut, normalization of increased intestinal permeability and altered gut microflora. Twelve different intestinal bacterial colonies were isolated from Black Tiger Shrimp (Penaeus monodon). Among them strain PPP 13 was studied and characterized due to...

Translationally controlled tumour proteins (TCTP) cDNA were cloned from the haemolymph of Scylla paramamosain by reverse transcription PCR using primers derived from Penaeus monodon. Nucleotide sequence analysis revealed 507 bp open reading frame (ORF) encoding 168 amino acid residues with a predicted molecular mass and pI of approximately 19.2 kDa and 4.5, respectively. Interestingly, mud crab...

A filamentous form of mollicute-like bacterium was detected during a routine health survey of wild adult kuruma shrimp Penaeus japonicus. The kuruma shrimp were native to Japan and were imported to Korea. The histology showed no pathological changes. Transmission electron microscopy revealed extensive infections of hepatopancreatic epithelial cells by a pleomorphic, filamentous intracellular ba...
