Expression and activity of recombinant proaerolysin derived from Aeromonas hydrophila cultured from diseased channel catfish.
Aerolysin is one of the putative toxins in extracellular products (ECP) produced by Aeromonas hydrophila, an important pathogen of catfish. To better understand the molecular mechanism and mode of action of this toxin, proaerolysin-coding gene was cloned from the genomic DNA of an A. hydrophila strain, cultured from diseased channel catfish, and heterologously expressed in E. coli. Functional r...
متن کاملEvasion of mucosal defenses during Aeromonas hydrophila infection of channel catfish (Ictalurus punctatus) skin.
The mucosal surfaces of fish serve as the first line of defense against the myriad of aquatic pathogens present in the aquatic environment. The immune repertoire functioning at these interfaces is still poorly understood. The skin, in particular, must process signals from several fronts, sensing and integrating environmental, nutritional, social, and health cues. Pathogen invasion can disrupt t...
متن کاملThe cytotoxic enterotoxin of Aeromonas hydrophila is aerolysin.
The channel-forming toxin aerolysin was identified 25 years ago by Bernheimer and Avigad (1), who gave the protein its name. Aerolysin was purified by Buckley et al. (2), and its structural gene, named aerA, was cloned and sequenced almost simultaneously by two groups (6, 7). Since then more than 50 articles describing the expression, secretion, and properties of aerolysin have appeared, and ae...
متن کاملParasitism by protozoan Ichthyophthirius multifiliis enhanced invasion of Aeromonas hydrophila in tissues of channel catfish.
Protozoan Ichthyophthirius multifiliis Fouquet (Ich) and bacterium Aeromonas hydrophila are two common pathogens of cultured fish, which cause high fish mortality. Currently there is no information available for the effect of parasitism by Ich on survival of channel catfish and invasion of A. hydrophila in fish tissues following exposure to A. hydrophila. A trial was conducted in this study to:...
متن کاملConstruction of vaccine from Lactococcus lactis bacteria using Aeromonas hydrophila virulent Aerolysin gene
In this study the forward and reverse primers were designated to amplify the segments (~250 bps and ~650 bps) of the gene coding domains 1 and 4 of aerolysin of Aeromonas hydrophila. These two domains are involved in pathogenesis of the aerolysin gene. Sequences for two restriction enzymes, Pst I and Hind III, were included in the forward and reverse primers respectively. These restriction enz...
