Expression studies on NA+/K(+)-ATPase in gills of Penaeus monodon (Fabricius) acclimated to different salinities.
The decapod crustacean Penaeus monodon survives large fluctuations in salinity through osmoregulation in which Na+/K(+)-ATPase (NKA) activity in the gills plays a central role. Adult P. monodon specimens were gradually acclimatized to 5, 25 and 35 per thousand salinities and maintained for 20 days to observe long-term alterations in NKA expression. Specific NKA activity assayed in gill tissues ...
متن کاملLethal attribute of serine protease secreted by Vibrio alginolyticus strains in kuruma prawn Penaeus japonicus.
Toxicity of the extracellular products (ECP) and the lethal attribute of serine protease secreted by five pathogenic Vibrio alginolyticus strains from various sources in kuruma prawn Penaeus japonicus were studied. The ECPs of organisms originally isolated from diseased kuruma prawn or small abalone Haliotis diversicolor supertexta were more lethal (LD50 value of 0.48 or 0.41 microg protein/g p...
متن کاملImmunodetection of specific Vibrio bacteria attaching to tissues of the giant tiger prawn Penaeus monodon
An in vitro study of the attachment of Vibrio pathogens to tissues of the giant tiger prawn Penaeus monodon (Fabricius, 1798) was carried out using species-specific and genus-specific monoclonal antibodies with indirect FITCimmunofluorescence microscopy. The attachment of V. alginolyticus and V. parahaemolyticus to different tissues was always stronger than the attachment of V. anguillarum, and...
متن کاملMechanisms of colour adaptation in the prawn Penaeus monodon.
Exposure of prawns to dark- or light-coloured substrates is known to trigger a strong colour adaptation response through expansion or contraction of the colouration structures in the prawn hypodermis. Despite the difference in colour triggered by this adaptive response, total levels of the predominant carotenoid pigment, astaxanthin, are not modified, suggesting that another mechanism is regula...
متن کاملCharacterization of antibiotic resistance in Vibrio spp. isolated from farmed marine shrimps (Penaeus monodon).
A total of 83 Vibrio isolates from farmed marine shrimps (Penaeus monodon) were tested for the presence of class 1, 2 and 3 integrons, SXT constin and tetracycline resistance-encoding genes. Mutations in the quinolone resistance-determining regions (QRDRs) of the gyrA and parC genes were determined in fluoroquinolone-resistant Vibrio strains (n=17). Five isolates were found to carry class 1 int...
