Hygienic assessment of combined disinfectants used in the service dog breeding of the penitentiary system in a comparative aspect

Abstract

Today, literacy and correctness of disinfection in service dog breeding are an urgent need. The choice of disinfectant, its concentration, temperature of the solution and the room, the method of application and other indicators play an important role here. The main thing is not to damage the olfactory center of service dogs, otherwise they will lose their search value. This is the purpose of studying the effectiveness of two disinfectants ("Kemisept" and "K-Dez AIR"), when using them in the conditions of the penal system in service dog breeding by irrigating various surfaces (concrete walls and floors, metal grates and wooden pallets). For the study, preliminarily, swabs were obtained from untreated surfaces and it was determined that in the control samples on Endo and XLD-agar media, the growth of enterobacteria colonies was detected, including Escherichia coli in significant quantities; on staphylococcal agar, a large growth of coccal microflora was noted in all samples. In MPA, growth of coccal microflora and spore-forming gram-positive rods Bacillus spp. was detected in all control samples. When treated with Kemisept and K-Dez AIR on intestinal media (Endo and XLDagar media), no growth of enterobacteria colonies was observed in all the studied samples. On staphylococcal agar, a smaller growth of coccal microflora was observed in the studied samples (concrete walls and floor) than in the control samples, and growth of single staphylococcal colonies was also established. Growth of a smaller number of coccal microflora was detected than in the control, growth of only single colonies of coccal microflora was noted. Thus, the results of disinfection of surfaces with two studied disinfectants (Kemisept and K-Dez AIR) are identical, the properties of both can be classified as bacteriostatic in relation to coccal microflora and bactericidal in relation to intestinal microflora.
