Mangroves are complex, unique, and dynamic ecosystems that host organisms have special physiological adaptations to fluctuations in salinity, temperature, pH. Gastropods an important role the mangrove ecosystem for food cycles webs by helping provide nutrients micro-habitats microbes. Micro-fungi isolated from productive sources of enzymes bioactive compounds such as antibacterial antifungal. I...

The bacterial flagellar motor is an elaborate molecular machine that converts ion-motive force into mechanical force (rotation). One of its remarkable features is its swift switching of the rotational direction or speed upon binding of the response regulator phospho-CheY, which causes the changes in swimming that achieve chemotaxis. Vibrio alginolyticus has dual flagellar systems: the Na(+)-dri...

The Outer Membrane Protein (OMP) of Vibrio alginolyticus cell wall was administered intramuscularly (IM) to the tiger shrimp (Penaeus monodon Fab.) at 10, 20, 30 μg/kg bw. After 14 days infection, the tiger shrimps were challenged with 10(7) bacterial density of Vibrio harveyi for 24 hours. The total haemocyte count (THC), differential haemocyte count (DHC) and amount of total protein plasma (T...

The capability of Vibrio alginolyticus to adhere to fish mucus is a key virulence factor of the bacteria. Our previous research showed that stress conditions, such as Cu(2+), Pb(2+), Hg(2+), and low pH, can reduce this adhesion ability. Non-coding (nc) RNAs play a crucial role in regulating bacterial gene expression, affecting the bacteria's pathogenicity. To investigate the mechanism(s) underl...

Six commercially available bacterial identification products were tested with Vibrio alginolyticus (12 strains), V. cholerae (30 strains), Photobacterium (Vibrio) damselae (10 strains), V. fluvialis (10 strains), V. furnissii (4 strains), V. hollisae (10 strains), V. metschnikovii (9 strains), V. mimicus (10 strains), V. parahaemolyticus (30 strains), and V. vulnificus (10 strains) to determine...

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...
