Assessment of the Safety of Anti-Salmonella Disinfectant for Veterinary Use Based on a Cocktail of Bacteriophages.

ABSTRACT

The toxicity and safety of a veterinary anti-salmonella disinfectant based on three highly virulent bacteriophage strains (titers 1010 PFU/ml) were studied. Acute, chronic, and inhalation toxicity, as well as local irritancy of the disinfectant were evaluated on outbred white mice CD1 (n=65), Soviet chinchilla rabbits (n=20), and rats (n=20). No toxic effects of the disinfectant was observed after its intraperitoneal or intragastric administration to mice and intragastric administration to rats; in rabbits, application on the skin and eyes produced no local irritation effect. Inhalation of 10% of the disinfectant did not cause any pathologies in mice. Thus, the tests confirmed the high level of safety of the disinfectant based on a mixture of bacteriophages for use as an additional specific disinfection agent against Salmonella in veterinary and livestock facilities.
