New BA-12 disinfectantfor disinfection soil foci of anthrax

Abstract

The territory of Kazakhstan is unfavorable for anthrax, officially registered since 1935, at present, the risk of outbreaks remains. One of the reasons is the presence of territories infected with the anthrax pathogen, soil foci of anthrax. Currently, the list of disinfectants is limited. Current developments are being carried out in order to create new compositions that have sporocidal properties for treating soil that is seeded with anthrax spores. We have developed and tested a new veterinary disinfectant "BA-12". Sporocidal properties of BA-12 were studied in laboratory and field conditions. The study was carried out using two methods: 1) using Batiste test objects seeded with spore -forming microorganisms-Bacillus cereus, Bacillus anthracis № 55, B. anthracis Tsenkovsky № 71/12 and immersing them in a disinfectant solution and in the soil. Different types of soil were used in the experiments. In the field, disinfect the soil of anthrax animal burial grounds in different regions of the Republic of Kazakhstan. The study of sporocidal activity of the drug "BA-12" in laboratory conditions on Batiste tests showed that the effectiveness of this solution is noted in 5%, 7%, 10%, 15% and 20% concentration and exposure of 60 minutes, and, more. The results of field studies show that when using 10% and 20% solutions of the BA-12 disinfectant on the territory of anthrax soil foci, they have a high sporocidal activity, completely inhibit the growth of spore- forming microorganisms.
