متن کاملkuruma shrimp, Penaeus japonicus
A filamentous form of mollicute-like bacterium was detected during a routine health survey of wild adult kuruma shrimp Penaeus japonicus. The kuruma shrimp were native to Japan and were imported to Korea. The histology showed no pathological changes. Transmission electron microscopy revealed extensive infections of hepatopancreatic epithelial cells by a pleomorphic, filamentous intracellular ba...
متن کاملLong-term ammonia toxicity to the pink-shrimp Farfantepenaeus paulensis.
Juvenile pink-shrimp Farfantepenaeus paulensis were exposed (75 days) to NH(3) (0.016-0.287 mg L(-1)) under static condition with water renewal every 24h. Experiments were performed at 20 degrees C, at a water salinity of 15 ppt, and at pH 7.8. Endpoints analyzed were survival, growth and predation rates. After 75 days of exposure, survival was >or=90% in all concentrations tested. However, gro...
متن کاملPenaeus vannamei isotrypsins: purification and characterization.
Three isotrypsins from digestive gland of Penaeus vannamei were purified and characterized by molecular, biochemical and kinetic parameters. Purified isotrypsins A, B, and C are glycoproteins with molecular masses between 30.2 and 32.9 kDa, and, therefore similar to other trypsins. The isoelectric points are anionic and different among the three isotrypsins: pH 3.5 for isotrypsin A, pH 3.0 for ...
متن کاملTranscriptional analysis of Penaeus stylirostris densovirus genes.
Penaeus stylirostris densovirus (PstDNV) genome contains three open reading frames (ORFs), left, middle, and right, which encode a non-structural (NS) protein, an unknown protein, and a capsid protein (CP), respectively. Transcription mapping revealed that P2, P11 and P61 promoters transcribe the left, middle and right ORFs. NS transcript uses the D1/A1 donor/acceptor sites for splicing and has...
