EPIZOOTOLOGICAL CHARACTERISTICS OF ECTOPARASITOSIS OF CARNIVORES IN THE MEGAPOLIS (BY THE EXAMPLE OF NOVOSIBIRSK)

The most well-known ectoparasites of dogs and cats are fleas and Acariformes, which are also carriers of infectious and invasive diseases. Animals admitted to the veterinary clinic served as the material for the research. The study involved 3346 animals, of which 1596 cats and 1707 dogs. Classical life-time diagnostic methods of ectoparasitosis were used. The results obtained show that among all dermatological patients, the proportion of those infected with ectoparasites was 47.6%. Among ectoparasites, fleas were most often recorded; the prevalence of infection was 4.78%. Aphanipterosis was recorded in all seasons of the year, the maximum invasion of 1.76% was observed in autumn, and the minimum of 1.30% in winter. The second most common disease was otodectosis (IP 1.94%). The heyletiellosis rate was 0.27% (total 9 animals, including 1 cat); and demodicosis, 0.24%. Notoedrosis was only diagnosed in the cats with IP 0.15%, sarcoptosis was recorded in the dogs with IP 0.09%. Ectoparasite infections are recorded at any time of the year, however, the peak of invasion occurs to a greater extent in the summer-autumn months. They can also occur at any age, but are more common in cats and dogs under one year of age.
