Expression analysis of channel catfish anterior kidney at 48h post immersion challenge of vaccinated fish (28 days post vaccination with attenuated Edwardsiella ictaluri) with virulent E. ictaluri

ABSTRACT: To determine the global gene transcriptional changes in vaccinated channel catfish anterior kidney after immersion challenge with a virulent Edwardsiella ictaluri compared to sham vaccinated catfish control. The attenuated Edwardsiella ictaluri used for vaccination was Aquavac-ESC which was commercially available, the virulent strain of Edwardsiella ictaluri is the AL93-58 strain.

Expression analysis of channel catfish anterior kidney at 48h post immersion challenge of vaccinated fish (28 days post vaccination with attenuated Edwardsiella ictaluri) with virulent E. ictaluri

Project description:To determine the global gene transcriptional changes in vaccinated channel catfish anterior kidney after immersion challenge with a virulent Edwardsiella ictaluri compared to sham vaccinated catfish control. The attenuated Edwardsiella ictaluri used for vaccination was Aquavac-ESC which was commercially available, the virulent strain of Edwardsiella ictaluri is the AL93-58 strain. A six chip study using total RNA samples including 3 controls (no vaccination, no challenge) and 3 treated groups (challenge after vaccination). Each RNA sample used for microarray was pooled fish anterior kidney samples (5 fish anterior kidney samples were pooled as one). Each chip measrues the expression level of 65,182 genes. For each sequence, 3 probes were selected. Two copies were prepared on arrays.

Expression analysis of Edwardsiella ictaluri 93-146 wild type and mutant strains during catfish fry encounter.

Project description:Edwardsiella ictaluri is the causitive agent of enteric septicemia of catfish, one of the most important diseases impacting US catfish industry. The overall objective of this study is to identify E. ictaluri genes required for host encounter. 4-plex NimbleGen array study using total RNA obtained from wild type and mutant Edwardsiella ictaluri encountered with or without catfish fry. Each treatment had four biological replica and each plex had two probe sets.

Project description:Edwardsiella ictaluri is the causitive agent of enteric septicemia of catfish, one of the most important diseases impacting US catfish industry. The overall objective of this study is to identify E. ictaluri genes required for serum resistance. 4-plex array study using total RNA obtained from wild type and mutant Edwardsiella ictaluri exposed to heat-inactivated catfish serum and normal serum. Each treatment had four biological replica and each plex had two probe sets.
