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 survey was carried out on the prevalence of bacteria and ciliate protozoan of Pellaells indiclls obtained from Ennore estuary, Chennai (Madras), India from November 1989 to July 1992. The study r~vealed the occurrence of Vibrio parahaemolyticus, V. VUlllijiCUS, V. harvey;, V. allguillarum, V. damsela, Pseudomollas sp., P. aemgillo.\'{/ and a tilamentous bacterium Leucothrix sp. This study als...

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...

Four species of penaeid prawn cultured in Australia (Penaeus monodon, Penaeus esculentus, Marsupenaeus japonicus and Fenneropenaeus merguiensis) were injected with a virulent preparation of gill-associated virus (GAV). P. monodon (average weight = 8.9, 13.9 and 19.2 g), P. esculentus (average weight = 19.5 g), F. merguiensis (average weight = 10.5 g), and small (average weight = 5.8 g) M. japon...

In aquaculture, shrimp farming is a popular field. The benefits of shrimp farming include a relatively short grow-out time, high sale price, and good cost recovery. However, outbreaks of serious diseases inflict serious losses, and acute hepatopancreatic necrosis disease (AHPND) is an emerging challenge to this industry. In South American white shrimp (Penaeus vannamei) and grass shrimp (Penaeu...
