Histopathology of Spiroplasma penaei Systemic Infection in Experimentally Infected Pacific White Shrimp, Penaeus vannamei
Penaeus vannamei shrimp were challenged with a suspension of a pathogenic isolate of Spiroplasma penaei prepared from a 72-h culture. The route of challenge was by intramuscular injection of the bacterial suspension into the third abdominal segment. Lesion development was evaluated in moribund shrimp collected and fixed in Davidson’s fixative 96 h post challenge. The predominant host responses ...
متن کاملVagococcus penaei sp. nov., isolated from spoilage microbiota of cooked shrimp (Penaeus vannamei).
A polyphasic taxonomic study, using phenotypic, phylogenetic and genotypic characterization, was performed on five Gram-stain-positive, catalase-negative, coccus-shaped Vagococcus-like bacteria isolated from the spoilage microbiota of cooked shrimp. Comparative 16S rRNA gene sequence analysis indicated that the isolates belonged to the genus Vagococcus. The five isolates shared 100% 16S rRNA ge...
متن کاملGenetic improvement of Pacific white shrimp [Penaeus (Litopenaeus) vannamei]: perspectives for genomic selection
The uses of breeding programs for the Pacific white shrimp [Penaeus (Litopenaeus) vannamei] based on mixed linear models with pedigreed data are described. The application of these classic breeding methods yielded continuous progress of great value to increase the profitability of the shrimp industry in several countries. Recent advances in such areas as genomics in shrimp will allow for the de...
متن کامل"Candidatus Hepatobacter penaei," an intracellular pathogenic enteric bacterium in the hepatopancreas of the marine shrimp Penaeus vannamei (Crustacea: Decapoda).
The bacteria that cause necrotizing hepatopancreatitis in Penaeus vannamei adversely affect penaeid shrimp cultured in the western hemisphere. 16S rRNA and gyrase B gene analyses determined the taxonomic position of these bacteria. The name "Candidatus Hepatobacter penaei" is proposed for these pathogenic bacteria, which are members of the Rickettsiales order.
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...
