Abstract

An updated nation-wide epidemiological survey of feline immunodeficiency virus (FIV) infection was conducted in Japan. Blood samples were collected from 1,770 outdoor accessing cats from March to October 2008. Serologically, 410 cats (23.2%) were positive for anti-FIV antibody. Proviral DNA of the FIV env V3-V5 region isolated from 348 cases could be phylogenetically analyzed. The present study disclosed a geographic distribution of four subtypes (A, B, C and D) of FIV in Japan. Even though an FIV vaccine was introduced in Japan, we do not currently know whether this vaccine is effective against all strains of FIV in Japan or not. Therefore, close attention still has to be paid to epidemic and genotypic trends of FIV.
