Abstract
Feline coronavirus (FCoV) is an enveloped single-stranded RNA virus, affecting wild and domestic cats. Feline infectious peritonitis viruses (FIPV) variants of FCoV cause fatal peritonitis affecting approximately 5% of FCoV infected animals. The present study aimed to detect and isolate the feline infectious peritonitis virus for the first time in Iraq. In this study, 50 samples (fecal swab and peritoneal fluid) were collected from suspected pet cats from different areas of Baghdad, Iraq. The very suitable age was under two years old. Real-time reverse transcription-polymerase chain reaction(real-time RT-PCR) was used to detect Feline infectious peritonitis in infected collected samples by the amplification of spike protein (S). The result of real-time RT-PCR revealed that out of 50 samples from suspected cats, 10 samples were positive for FIPV. Moreover, 10 positive samples by real-time RT-PCR were used for the isolation of the virus in chicken embryo fibroblast cell culture. Subsequently, the isolated virus was detected by real-time RT-PCR and then by conventional RT-PCR, followed by electrophoresis.
