ABSTRACT
Feline coronavirus (FCoV) is a highly contagious and ubiquitous virus of domestic cats and wild felids. Feline infectious peritonitis (FIP) is a fatal, systemic disease caused by FCoV infection when spontaneous mutations of the viral genome take place. The aims of this study were primarily to determine the prevalence of seropositivity for FCoV in different populations of cats in Greece and assess risk factors for seropositivity. A total of 453 cats were prospectively enrolled in the study. A commercially available IFAT kit was used for the detection of FCoV IgG antibodies in serum. Overall, 55 (12.1 %) of the 453 cats were seropositive for FCoV. Based on multivariable analysis, factors associated with FCoV-seropositivity included cats adopted as strays and contact with other cats. This is the first extensive study on the epidemiology of FCoV in cats from Greece and one of the largest worldwide. Feline coronavirus infection is relatively common in Greece. Therefore, it is necessary to establish optimal strategies for the prevention of FCoV infection, considering the high-risk groups of cats identified in this study.
