    Characterization of Aeromonas hydrophila isolated from diseased fish and the potential of sodium alginate as a carrier for oral vaccine
    (Terengganu: Universiti Malaysia Terengganu, 2013-12) Nurul Aqilah Iberahim
    Bacterial diseases in aquaculture are considered to be a major cause of fish mortalities. Disease due to Aeromonas hydrophila is one of the most common bacterial diseases in aquaculture. This bacterium causes hemorrhagic septicaemia, abdominal dropsy and ulcers. Effective prevention is necessary to overcome the outbreak of bacterial disease. Thus this study was conducted to isolate, identify and characterize A. hydrophila from diseased fish. The virulence and pathogenicity of the isolates were evaluated for vaccine candidate selection. The in vitro suitability of sodium alginate as coating agent for oral formalin killed A. hydrophila vaccine was evaluated. A. hydrophila were isolated, identified and characterized using conventional biochemical tests. Two representative isolates were subjected to 16S rRNA gene sequencing and analysed for identity confirmation.

    Mud crabs are among the commercially important aquatic animals because of high demand in Asian countries. Currently, one of the main constraints for expansion of mud crab aquaculture is the inconsistent and low hatchery production of crab juveniles. The use of beneficial bacteria offers a promising approach in aquaculture to prevent infections by pathogenic bacteria, and has been shown to help reduce mortality after infection. The goals of this study were to isolate, identify and evaluate potential probiotic bacteria from the gut of wild orange mud crab from Setiu Wetlands, Terengganu.
