Insecticid efficiency of preparations in ctenocephalesis in dogs in conditions of the Tyumen city

Fleas are a group of blood-sucking arthropods belonging to the Siphonaptera group, they are of great importance in veterinary medicine not only because of their pathogenic activity on the host organism, but also because they are carriers of various diseases such as plague, typhus, encephalitis, hepatitis B and C, tularemia, listeriosis, toxocariasis and others. The most important of these insects are in dogs, cats and other animals, but their ability to use as an alternative human host determines the importance of these parasites in the health sector. With the presence of warm-blooded flea infestations, the disease is called ctenocephalesis; in dogs, it is one of the most common ectoparasitic skin epidermis diseases, which is difficult to treat and causes significant economic damage to both the owners of dogs and all types of cynological activity. When the flea bites on the skin, an inflammatory compaction is formed, a strong itching, which turns into miliary dermatitis. However, the most serious damage animals do to themselves, it''s combing and gnawing skin and wool cover at the places of flea bites, all this leads to the formation of areas of alopecia, wet eczema, and the introduction of pathogenic microflora into the damaged tissue. The aim of the study was to study the insecticide properties of the "Comfortis" and "Bravecto" preparations in the case of ctenocephalesis in dogs. At the end of the studies, it was found that the use of the insecticacaride fluralaner Bravecto in a dose of 25 mg / kg with a single application orally at the time of ingestion showed 100% therapeutic efficacy by the 25th day of the study, and the use of the insecticide "Comfortis" 50 mg / kg by the 30th day.
