The implication of metabolically active Vibrio spp. in the digestive tract of Litopenaeus vannamei for its post-larval development.

ABSTRACT: This work aimed to evaluate the link between the occurrence/abundance of Vibrio populations and bacterial composition in shrimp's intestine (Litopenaeus vannamei) during post-larval ontogenetic development and in its culture water, and the correlation of these with environmental parameters. The total and metabolically active populations of Vibrio in the digestive tract of shrimp during its post-larval development were analysed using quantitative PCR (qPCR) and reverse transcription qPCR targeting the 16S rRNA gene sequence. A lab-scale shrimp bioassay was performed for 80 days in a recirculating aquarium under strictly controlled conditions. The results indicate that the Vibrio population from shrimp's gut is associated with its developmental stage and the environment. Multivariate analyse
