Microbiota from Litopenaeus vannamei: digestive tract microbial community of Pacific white shrimp (Litopenaeus vannamei)
Bacteria capable of producing different extracellular enzymes of potential relevance in digestive processes were isolated from the stomach, hepatopancreas and intestine of Pacific white shrimp Litopenaeus vannamei. A total of 64 strains with proteolytic activity were isolated and grouped into 16 clusters based on morphological characteristics: 4 groups were isolated from the intestine; 5 from t...
متن کاملEffect of water temperature on the immune response of white shrimp Litopenaeus vannamei to Vibrio alginolyticus
White shrimp Litopenaeus vannamei held in 25x seawater at 27 8C or 28 8C were injected with TSB-grown Vibrio alginolyticus at 1 10 colony-forming units (cfu) shrimp 1 or 1 10 cfu shrimp , and then cultivated onward at water temperatures varying from 20 to 34 8C. Over 24–144 h, mortality of V. alginolyticus-injected shrimp held at 34 8C or 32 8C was significantly higher than that of shrimp held ...
متن کاملEffects of dietary astaxanthin on the immune response, resistance to white spot syndrome virus and transcription of antioxidant enzyme genes in Pacific white shrimp Litopenaeus vannamei
Three different experiments were conducted to study the effect of dietary astaxanthin on the immune response, resistance to white spot syndrome virus (WSSV) and transcription of antioxidant enzyme genes in Pacific white shrimp Litopenaeus vannamei. Each experiment included one triplicate treatment group (fed with 80 mg/kg astaxanthin supplemented diet) and one triplicate control group (fed with...
متن کاملGene set based association analyses for the WSSV resistance of Pacific white shrimp Litopenaeus vannamei
White Spot Syndrome Virus (WSSV) is regarded as a virus with the strongest pathogenicity to shrimp. For the threshold trait such as disease resistance, marker assisted selection (MAS) was considered to be a more effective approach. In the present study, association analyses of single nucleotide polymorphisms (SNPs) located in a set of immune related genes were conducted to identify markers asso...
