Evaluation of the effectiveness of preventive disinfection measures based on a comprehensive analysis of the microbiome of service dogs‘ places of detentionКоррозионное действие растворов N,N-бис(3-аминопропил)додециламина и их смесей с алкилдиметилбензиламмоний хлоридом

The article presents the results of a qualitative and quantitative analysis of the microbiome of places where dogs of service breeds are kept, obtained under the conditions of rotation of medicines for an active substance. In the period from 2017 to 2021, dynamic observations were made to assess the effectiveness of preventive disinfection measures carried out in the cynological town. The object of the study was the micro-and mycoflora of more than 20 dog enclosures in two versions: before disinfection and after mechanical treatment and fine-drip irrigation with preparations recommended for disinfection of veterinary surveillance facilities. Using differential diagnostic nutrient media, representatives of different groups of microorganisms were isolated from the surfaces of inventory, poilushki, the floor and walls of the walking enclosures. A qualitative analysis of biodiversity revealed that microbial isolates are conditionally pathogenic microorganisms and can be potentially dangerous infectious agents. The results showed that disinfection measures were not sufficiently effective against the selected groups of microorganisms. Using elective nutrient media, cultures of yeast-like and mold-like micromycetes were isolated from the surfaces of walking enclosures. The analysis of the data showed that both decompositions, claimed to be effective against mold micromycetes, do not withstand the contaminating load. The method of small-drop irrigation used for processing the walking of the kennels of the cynological town turned out to be low-effective in relation to the isolated microbial and fungal isolates. Within the framework of compliance with the sanitary and hygienic regime, an algorithm for organizing preventive disinfection measures in the cynological unit has been developed, based on the well-coordinated interaction of support services: medical, logistics, sanitary and veterinary. The research conducted jointly with representatives of the veterinary and sanitary service, with cadets of the cynological faculty, is of great practical importance for the formation of the professional competence of future officers – specialists-cynologists, heads of cynological units. The developed recommendations make it possible to adjust the algorithm of sanitary and hygienic measures in the cynological town and are of great importance in solving health-saving issues and maintaining the number of dogs of service breeds.
