Evaluation of sporicidal action of new biocidal preparation «Dezosteril-forte»

High-level biological safety is ensured by due detection and destruction of pathogenic biological agents, reservoirs of infections. Disinfection is one of the most important factors in the system of veterinary and sanitary control. It is impossible to achieve high-level biological safety in various branches of agricultural industry with out modern multifunctional biocidal preparations. One of such multifunctional drugs is "Desosteril-forte”, which composition includes detergent substances and substances with bactericidal effect from various classes of organic compounds. The balance of these substances gives the drug its multifunctional effect (washing, disinfecting and degreasing properties). This article shows experiment results on the evaluation of sporicidal properties of "Desosteril-forte" on various building materials. Laboratory experiments revealed sporicidal effect of biocidal preparation "Dezosteril-forte" on various test surfaces: objects of stainless steel, tile, wood and rubber. Lyophilized dried spores of Bacillus cereus (IP 5832) were used as spore test cultures. To imitate production environment, a protein-fat mixture was applied on the test surface in the amount of 0.5 g / 100 cm2. The sporicidal effect of the drug revealed itself at a 3% concentration and 180 minutes exposure on steel, tile and rubber test surfaces, as for wooden test surfaces, the sporicidal effect of the drug was observed using a 4% concentration at 120 minutes exposure. The results of the experiments showed correlation between concentration, exposure time and structure of the test-surface material. Porous surfaces (wood) required bigger concentration and exposure time for their disinfection.
