Channel 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 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 کاملPathogenicity of Streptococcus ictaluri to channel catfish.
The pathogenicity of a Streptococcus ictaluri isolate in channel catfish Ictalurus punctatus at the fry (0.5 g), fingerling (15 g), and juvenile (55 g) stages was determined by experimental bath immersion and injection experiments. Channel catfish were exposed in 1-L immersion baths containing 10(8), 10(9), 10(10), 10(11) or 10(12) colony-forming units (cfu) of S. ictaluri. Fish were also injec...
متن کاملAntimicrobial Activity of Vinegar on Bacterial Species Isolated from Retail and Local Channel Catfish (Ictalurus punctatus)
There is an increasing interest in applying natural antimicrobial compounds in the food industry. Consumers are increasingly avoiding the consumption of foods treated with chemicals. Natural alternatives are needed to achieve a high level of safety with respect to foodborne pathogenic microorganisms [1]. The natural sanitizers, such as organic acids, have been investigated because of their bact...
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...
