DETERMINATION OF THE DISINFECTING PROPERTIES OF THE «BACTERIDEZ VET» AGENT IN LABORATORY CONDITIONS

Abstract

Laboratory studies of the agent «Bacteridez Vet» were carried out, during which it was found that it has disinfectant properties. The studies were carried out on reference strains of microorganisms: Escherichia coli (strain 1257), Staphylococcus aureus (strain 209-P), Mycobacterium (strain B-5), Bacillus cereus (strain 96) and test samples made of smooth and rough materials used at veterinary surveillance facilities. Studies have shown that disinfection of artificially infected E. coli strain 1257 and S. aureus strain 209-P test surfaces achieved: smooth (stainless steel, tile) – 0,1%, rough (wood, concrete) – 1% solutions when exposed to the agent 1 hour, the rate of consumption of the agent 0,25–0,5 l/m2 for all types of surfaces. Disinfection of test surfaces made of wood and concrete contaminated with highly resistant and especially resistant microorganisms was achieved by double spraying, exposure of 24 hours for mycobacteria – 4% concentration, for spores of B. cereus strain 96-6%.
