Development 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 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...
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 کاملEffects of cortisol and stress on channel catfish (Ictalurus punctatus) pathogen susceptibility and lysozyme activity following exposure to Edwardsiella ictaluri.
Periods of stress are often associated with disease outbreaks in cultured fish, and stress is often characterized by the secretion of cortisol. Although stress and cortisol secretion are highly correlated in fish, the role of cortisol in affecting channel catfish (Ictalurus punctatus) pathogen susceptibility is unclear. The effects of short-term stress and exogenous cortisol administration on c...
