Pathogen loads, clearance and plasma cortisol response in channel catfish, Ictalurus punctatus (Rafinesque), following challenge with Edwardsiella ictaluri.
Enteric septicaemia of catfish (ESC), caused by the Gram-negative bacterium Edwardsiella ictaluri (Hawke 1979), is the most prevalent disease affecting farm-raised catfish in the southeastern United States. The disease occurs primarily in the autumn and spring when water temperatures are between 18 and 28 !C (Francis-Floyd, Beleau, Waterstrat & Bowser 1987). The number of ESC cases investigated...
متن کاملDevelopment of a novobiocin-resistant Edwardsiella ictaluri as a novel vaccine in channel catfish (Ictalurus punctatus).
The efficacy of a novel attenuated Edwardsiella ictaluri vaccine (B-50348) was determined in channel catfish (Ictalurus punctatus) by bath immersion and intraperitoneal (IP) injection. The vaccine was developed from a virulent strain of E. ictaluri (AL93-58) through selection for novobiocin resistance. When channel catfish (average weight 10 g) were IP injected with 4.2 × 10⁶ colony-forming uni...
متن کاملChannel Catfish Ictalurus punctatus
We used a two-compartment, clearance volume-based model to examine rubidium and cesium Ž . pharmacokinetics in channel catfish Ictalurus punctatus after intravascular administration. We compared the apparent volumes of distribution in the central and peripheral compartments and the intercompartmental and whole-body clearances of both metals at 20.0 8C and 27.5 8C. Biological half-times of Rb we...
متن کاملGrowth Response and Resistance to Edwardsiella ictaluri of Channel Catfish, Ictalurus punctatus, Fed Diets Containing Distiller’s Dried Grains with Solubles
A study was conducted to examine the effect of dietary levels of distiller’s dried grains with solubles (DDGS) on growth, body composition, hematology, immune response, and resistance of channel catfish, Ictalurus punctatus, to Edwardsiella ictaluri challenge. Five diets containing 0, 10, 20, 30, and 40% DDGS with supplemental lysine (Diets 1–5) as partial replacements of a combination of soybe...
متن کاملIn vitro and in vivo interaction of macrophages from vaccinated and non-vaccinated channel catfish (Ictalurus punctatus) to Edwardsiella ictaluri.
Macrophages from catfish vaccinated with an Edwardsiella ictaluri vaccine and macrophages from non-vaccinated catfish were used in in vitro and in vivo studies with red-fluorescent E. ictaluri to assess phagocytic ability, reactive oxygen and nitric oxide production and bactericidal activity. In the in vitro experiment, macrophages were harvested from vaccinated and non-vaccinated fish and then...
