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 کاملShort communication. SNP analyses of the 5HT1R and STAT genes in Pacific white shrimp, Litopenaeus vannamei
Shrimp aquaculture is one of the growing animal industries. Breeding stocks with high disease-resistance and growth rate are of particular interest to shrimp breeders. Association studies are useful to find genetic markers for marker assisted selection of animals. Using six Litopenaeus vannamei individuals from a sample population, four single nucleotide polymorphisms (SNPs) were found in the 5...
متن کاملTranscriptome Analysis of the Hepatopancreas in the Pacific White Shrimp (Litopenaeus vannamei) under Acute Ammonia Stress
In the practical farming of Litopenaeus vannamei, the intensive culture system and environmental pollution usually results in a high concentration of ammonia, which usually brings large detrimental effects to shrimp, such as increasing the susceptibility to pathogens, reducing growth, decreasing osmoregulatory capacity, increasing the molting frequency, and even causing high mortality. However,...
متن کاملSNP Discovery in the Transcriptome of White Pacific Shrimp Litopenaeus vannamei by Next Generation Sequencing
The application of next generation sequencing technology has greatly facilitated high throughput single nucleotide polymorphism (SNP) discovery and genotyping in genetic research. In the present study, SNPs were discovered based on two transcriptomes of Litopenaeus vannamei (L. vannamei) generated from Illumina sequencing platform HiSeq 2000. One transcriptome of L. vannamei was obtained throug...
متن کاملLocalization and bacteriostasis of Vibrio introduced into the Pacific white shrimp, Litopenaeus vannamei.
Although numerous mechanisms of immune defense have been described in crustaceans, the tissue distribution and fate of live bacteria introduced into the host remain unclear. In the present study, Litopenaeus vannamei were injected with a sub-lethal dose of kanamycin-resistant Vibrio campbellii expressing green fluorescent protein. Accumulation of intact bacteria was quantified by real-time PCR,...
