Draft Genome Sequence of a Vibrio harveyi Strain Associated with Vibriosis in Pacific White Shrimp (Litopenaeus vannamei)
Vibrio harveyi is a Gram-negative bacterium associated with vibriosis in penaeid shrimp. Here, we report the draft genome sequence of a V. harveyi strain isolated from Pacific white shrimp (Litopenaeus vannamei) during a vibriosis outbreak. The availability of this genome will aid future studies of vibriosis in shrimp aquaculture.
متن کاملLysozyme gene expression by hemocytes of Pacific white shrimp, Litopenaeus vannamei, after injection with Vibrio.
The purpose of this study was to quantify the gene expression of lysozyme, an important antibacterial protein produced by shrimp hemocytes, within tissues of Litopenaeus vannamei Boone in response to a pathogen challenge. We quantified lysozyme transcripts with a real-time PCR method and used these data, along with total hemocyte counts, to infer patterns of hemocyte trafficking during the immu...
متن کاملDraft genome sequence of the shrimp pathogen Vibrio harveyi CAIM 1792.
Vibrio harveyi is a Gram-negative bacterium found in tropical and temperate marine environments as a free-living organism or in association with aquatic animals. We report the first sequenced genome of a Vibrio harveyi strain, CAIM 1792, the etiologic agent of the "bright red" syndrome of the Pacific white shrimp Litopenaeus vannamei.
متن کاملMicrobiota 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 کاملA Nonluminescent and Highly Virulent Vibrio harveyi Strain Is Associated with “Bacterial White Tail Disease” of Litopenaeus vannamei Shrimp
Recurrent outbreaks of a disease in pond-cultured juvenile and subadult Litopenaeus vannamei shrimp in several districts in China remain an important problem in recent years. The disease was characterized by "white tail" and generally accompanied by mass mortalities. Based on data from the microscopical analyses, PCR detection and 16S rRNA sequencing, a new Vibrio harveyi strain (designated as ...
