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...

Eight novel microsatellite loci from the genome of Fenneropenaeus penicillatus Alcock were developed using the protocol of fast isolation by amplified fragment length polymorphism of sequences containing repeats (FIASCO). Thirty (30) wild individuals were used to analyze the polymorphism of these eight microsatellite markers. The results show that the number of alleles per locus and the polymor...

An experiment was conducted to explore the pathogenic effect of WSSV infection in reproduction of the Indian white shrimp, Fenneropenaeus indicus by investigating the time-course expression of female reproduction gene, namely vitellogenin (Vg) and thrombospondin (TSP), following WSSV challenge. Increased levels of expression for both Vg and TSP was observed in the infected group at 30 h post-in...

We identified 38 genes and eight hypothetical proteins by sequencing of 1200 clones from a Vibrio harveyi challenged Fenneropenaeus indicus subtracted cDNA library. Based on physiological roles and functions these genes were categorized into 10 groups with ∼29% of the sequences having no matches in the databases. Immune related transcripts in the library were carboxypeptidase B, ferritin, trans...

in this study, partial and complete replacement of live food ( artemia nauplii) with a microdiet was investigated in post-larval indian white shrimp, fenneropenaeus indicus . post-larvae (pl 1 ) were stocked into nine 20-l vessels (5-l water volume) at a density of 50 l -1 . shrimp were fed six times a day over 10 days. at the end of the feeding period, there was no significant difference in qu...

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...
