Ectozoans of dogs and cats

The purpose of the study is to analyze the species composition and distribution of ectoparasites of dogs and cats on the territory of the Russian Federation. Research objectives: to study the epizootic situation regarding ectoparasites of dogs and cats on the territory of the Russian Federation. Ectoparasites of dogs and cats are widespread in the Russian Federation and pose the greatest danger as carriers of pathogens of infectious and invasive diseases. Depending on the region, the species composition and abundance of ectoparasites varies significantly. Thus, in Moscow, aphanipterosis (46–62%), otodectosis in cats (34–38%) and demodicosis in dogs (39%) were more often recorded. When examining dogs in Tyumen with diseases of the skin and hair, skin diseases of parasitic etiology were recorded in 33.86% of all examined animals. Aphanipteriosis was detected more often – 28.55%, otodectosis – 21.9%, flea allergic dermatitis – 14.65%, cheyletiosis – 13.2%, demodicosis – 12.6%, sarcoptic mange – 9.1%. A study of dogs and cats in Novosibirsk identified 6 types of parasites: Ctenocephalides canis, Otodectes cynotis, Demodex canis, Notoedres cati, Sarcoptes canis and Cheyletiella jascuri. Among cats and dogs. the most common were: aphanipterosis 4.8%, otodectosis 1.9%, demodicosis 0.23%, notoedrosis 0.14%, sarcoptic mange 0.09% and cheyletiellosis 0.3%. In the Nizhny Novgorod region, dogs and cats were diagnosed with infestation of two types of fleas (Ctenocephalides felis, C. canis), one type of lice-eater (Trichodectes canis), in addition, the following were found on the animals’ bodies: dog louse (Linognathus setosus), ixodid ticks Dermacentor reticulates, D. marginatus and I. ricinus. Thus, aphanipterosis (4.78–62.0%) and demodicosis (2.52–39.0%) are more often recorded in dogs; trichodectosis (0.64–4.2%) and ixodid ticks (9.75%) are less common. –18.0%), sarcoptic mange (1.0–9.1%), otodectosis (0.17–1.94%), and in cats – otodectosis (34–63%), notoedrosis (0.31–8.9%) and cheyletiellosis (0.27%).
