Striped catfish or Vietnamese mainly contributes to national aquaculture exports. However, bacterial diseases result in the decrease of striped production efficiency and most popular disease is hemorrhagic septicemia caused by Aeromonas hydrophila. Bacteriophages viruses have been investigated as alternative biological agents control pathogenic infections for many decades. A few genomes A. hydr...

Philippine catfish, Clarias batrachus farming is receiving much attention in recent years so also the diseases in catfish aquaculture. During the disease surveillance in catfish farms, mortalities were observed in C. batrachus fingerlings in a nursery and this report describes the bacteriological and histopathological observations made on the diseased catfish. The gross and clinical signs obser...

A facultative anaerobic bacterium, designated as strain SCS5, was isolated from the anodic biofilm of a mediator-less microbial fuel cell using acetate as the electron donor and α-FeOOH as the electron acceptor. The isolate was Gram-negative, motile, and shaped as short rods (0.9-1.3 μm in length and 0.4-0.5 μm in width). A phylogenetic analysis of the 16S rRNA, gyrB, and rpoD genes suggested t...

Due to the increasing resistance of aquaculture pathogens antibiotics, search for new approaches control infectious diseases is particular importance. A promising approach development probiotic preparations based on antagonist bacteria. The paper studied antagonistic activity Bacillus strains that are developing probiotics fish. were isolated from bottom sediments Don River in area Donskoy Fish...

Fragments of the glycoprotein genes of viral hemorrhagic septicemia virus (VHSV) and infectious hematopoietic necrosis virus (IHNV) were cloned into a bacterial broad-host-range expression vector under the control of the plac promoter. Western blot (immunoblot) analysis with monoclonal antibodies specific to the glycoproteins demonstrated the inducible expression of the fusion proteins in Esche...
