Penaeus 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 کاملTaura 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 کاملCharacterization of a rediscovered haplosporidian parasite from cultured Penaeus vannamei.
Mortalities of Penaeus vannamei, cultured in ponds in Belize, Central America, began during the last part of the grow-out cycle during the cold weather months from September 2004 through February 2005. Tissue squashes of infected hepatopancreata and histological examination of infected shrimp revealed that the mortalities might have been caused by an endoparasite. To confirm the diagnosis, DNA ...
متن کاملAquacultural importance of the integumental pore pattern in postlarval whiteleg shrimp Litopenaeus vannamei (Decapoda: Penaeidae).
The analysis of integumental pore pattern has identified two intraspecific groups of postlarval shrimp Litopenaeus vannamei (Boone, 1931), a species of which three to five natural populations or groups are expected to be found from Mexico to Peru. Natural distribution and man-made redistributions have not been typified on a population basis in any penaeid, but it is important to do so in this c...
متن کاملVariability of, and the influence of environmental factors on, the recruitment of postlarval and juvenile Penaeus merguiensis in the Matang mangroves of Malaysia
Postlarval and small juvenile Penaeus merguiensis were sampled fortnightly by beam trawls on the ebb tides over 4 years in the Matang mangroves on the west coast of peninsular Malaysia. Larger juveniles were sampled by bag nets on both the ebb and flood tides every fortnight over 5 years. Rainfall is consistently high throughout the year (>100 mm in each month) and the annual rainfall ranges fr...
