Objective. Several studies from different countries have been performed about the viral diseases of domestic cats, and detailed information has been provided on their transmission, prevalence/incidence, virulence, origins/molecular characteristics and pathogenesis so far. Multiple- or co-infections in domestic and wild cats have been described by many papers. However, viral co-infections have been reported on a limited basis. In this study, three domestic clinically diseased cats have been found to be positive with feline coronavirus (FCoV), feline parvovirus (FPV) and feline foamy virus (FFoV). We aimed to examine triple viral infections circumstances in Turkish cats. Material and method. Ascites and blood samples were collected from diseased cats. Different polymerase chain reaction protocols for each virus were performed. After PCRs, all products were run in agarose gel and visualized under a blue-light transilluminator. Results. We found FCoV, FPV and FFoV as triple infection in three cats. Conclusions. We think that the results indicating the presence of multiple infections will ease the work of veterinary clinicians concerning infection treatment options, especially when animals show multiple clinical findings due to co-infections. It should be not forgotten the presence of multi-systemic co-infections in early routine laboratory diagnosis.
