Vibrio harveyi and the 'green water culture' of Penaeus monodon
The “greenwater culture” of the tiger shrimp, Penaeus monodon, is an innovative culture technique for the grow-out rearing of shrimps. This culture method involves the use of rearing water of tilapia for the rearing of tiger shrimp in grow-out ponds and or the polyculture of shrimp with tilapia. This culture technique was reported to prevent disease outbreaks attributed to luminescent Vibrio. T...
متن کاملInhibition of luminescence and virulence in the black tiger prawn (Penaeus monodon) pathogen Vibrio harveyi by intercellular signal antagonists.
Expression of luminescence in the Penaeus monodon pathogen Vibrio harveyi is regulated by an intercellular quorum sensing mechanism involving the synthesis and detection of two signaling molecules, one of which is N-hydroxy butanoyl-L-homoserine lactone and the other of which is uncharacterized. Indirect evidence has suggested that virulence, associated with a toxic extracellular protein, and l...
متن کاملIdentification of upregulated immune-related genes in Vibrio harveyi challenged Penaeus monodon postlarvae.
A subtracted cDNA library was constructed and analyzed to elucidate the response of Penaeus monodon postlarvae challenged with Vibrio harveyi. As many as 960 randomly selected cDNA fragments generated through suppression subtractive hybridization were single pass sequenced. Forty five genes and 20 hypothetical proteins were identified, a few being first reports from shrimps. The most abundant i...
متن کاملStudies on luminous, Vibrio harveyi associated with shrimp culture system rearing Penaeus monodon.
Microbiological studies in a modified extensive shrimp culture system at Nambuthalai, southeast coast of India were carried out fora period of 120 days. Population dynamics and distribution profile of luminous bacteria and total heterotrophic bacteria in the water sediment and animal samples were monitored. Luminous bacteria associated with exoskeleton, gills and gut were isolated and quantifie...
متن کاملCharacterization of antibiotic resistance in Vibrio spp. isolated from farmed marine shrimps (Penaeus monodon).
A total of 83 Vibrio isolates from farmed marine shrimps (Penaeus monodon) were tested for the presence of class 1, 2 and 3 integrons, SXT constin and tetracycline resistance-encoding genes. Mutations in the quinolone resistance-determining regions (QRDRs) of the gyrA and parC genes were determined in fluoroquinolone-resistant Vibrio strains (n=17). Five isolates were found to carry class 1 int...
