Molecular investigation of feline calicivirus in cats in Mosul city, Iraq

Abstract

The study included 200 cats of different ages, genders, types of breeding, source, vaccination programs, and health status. They were examined clinically and traditionally and recorded clinical signs appearing on them, and swabs were collected from the eye's conjunctiva and the pharyngeal area. RNA was extracted from the swabs and then converted into a cDNA molecule to investigate viral nucleic acid from collected swabs. Then, the open reading template gene two was detected using the primer for this within the applied polymerase chain reaction technique. The Molecular method found the highest infection rate in the oropharyngeal compared with conjunctival swabs. It was found in the highest percentage of infection in the age group more than six months, and the rate of infection decreased with age and in cats outdoors management and imported ones. While nonvaccinated cats recorded the highest rate of infection with the feline calicivirus. In conclusion, feline calicivirus affected the cats in Mosul, Iraq.
