The spread of viral infections among the cats of the city of Krasnoyarsk

The indicators of epizootic process of viral diseases of the cats in Krasnoyarsk in the period from 2017 to 2019 were studied. The diagnosis of viral infections was made based on complex approach, considering epizootological data, clinical signs with the examination of biomaterials confirmed by polymerase chain reaction (PCR). The objects of the research were domestic cats of different age groups and breeds belonging to private owners. As a result of the study, etiological structure of viral infection of cats has been established: FCV, FHV-1, FPV - by agent's monovariant and in associative forms. The morbidity rate of cats’ calicivirosis reached its highest point at 19.4 %. The animals at the age between 1 month and 1 year are more often infected. The cats of different breeds are susceptible to FCV: British - 24.5 % of cases, Scottish visuals (14.6 %), sphinx (10.4 %), but more frequently the cases of infection were observed among outbred species (32.4 %). In case of panleucopenia, the morbidity rate was 16.1 %. Cats' susceptibility to FPV proved to have no breed dependence. The infection of the animals occurs year-round, the number of cases in spring (27.8 %) and summer (23.5 %) months is slightly higher than in autumn (23.1 %) and in winter (25.6 %). The incidence rate of infectious rhinotracheitis of cats made 14.7 %. The susceptibility and incidence rate of cats’ infectious rhinotracheitis according to the breed showed no reliable differences. Seasonal fluctuations in morbidity rate were slight, increasing throughout spring and winter months.
