Taura syndrome virus from Penaeus vannamei shrimp cultured in Korea.
Mass mortality occurred among Penaeus vannamei shrimp cultured in Korea in 2004. In an earlier study, we reported white spot syndrome virus (WSSV) as a causative agent of mass mortality of P. monodon shrimp in Korea (Moon et al. 2003; Dis Aquat Org 53:11-13). However, in the present study, we detected Taura syndrome virus (TSV) from the moribund 2004 P. vannamei shrimp by reverse transcription ...
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 کاملHistopathology 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 کاملMicrobiota of Vibrio sp. in the hepatopancreas of cultured white pacific shrimp (Litopenaeus vannamei) Vibrio sp., microbiota en el hepatopáncreas del camarón blanco del Pacífico (Litopenaeus vannamei)
Objective. The present study aimed to investigate the presence of vibrios in the hepatopancreas of cultured shrimp. Materials and methods. Vibrios from the hepatopancreas of fifteen samples of five specimens each, of apparently healthy Pacific white shrimp (Litopenaeus vannamei) were isolated, identified and quantified. Results. The vibrio density ranged from 430 to 2,400 MPN g-1 (rs MPN cm-1=-...
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...
