Feline immunodeficiency virus (FIV) and feline leukaemia virus (FeLV) are retroviruses affecting felid species worldwide. A study was performed over a period of 5 months in Ireland with the aim to get an updated and more realistic prevalence of these retroviruses. A total of 183 EDTA-anticoagulated whole-blood samples were collected from cats distributed between 10 clinics. The samples were tested using both point-of-care enzyme-linked immunosorbent assay (ELISA) and polymerase chain reaction (PCR). Basic clinical data and vaccination history were also recorded for the sampled cats. The results of ELISA tests showed a prevalence of 10.4 and 3.3% for FIV and FeLV, respectively, and an apparent prevalence of 9.3% for FIV and 11.6% for FeLV with PCR. Phylogenetic analysis of the partial polymerase (pol) gene sequences obtained from 8 FIV-positive strains showed that all but one of the Irish strains belonged to FIV subtype A, and one to subtype B. The overall mean genetic similarity between the analysed strains was 91.15%.
