Abstract

A door-to-door survey was conducted within the limits of the suburb of Douglas in northern Queensland, Australia, to determine the prevalence of feline immunodeficiency virus (FIV) infection in the overall population of domestic cats. Previous FIV prevalence studies have relied on convenience sampling strategies, leaving out an important group of pet cats that do not receive regular veterinary attention. Saliva was selected for testing because collection was non-invasive and was likely to achieve a high rate of participation. Ninety-six cats were surveyed and tested for salivary antibodies against FIV and with real-time polymerase chain reaction (PCR). PCR was considered to be the gold standard and a cat was considered to be FIV-positive if sequencing results on a PCR product of appropriate size matched previously published FIV genome sequences available in GenBank. Results showed 10/96 cats to be infected with FIV subtype A, indicating a prevalence of 10.4% (95% confidence interval: 4.4-16.4) in the area studied. High risk associations were established with the roaming lifestyle of the cat (P <0.002), presence of abscesses (P <0.03) and occurrence of bite wounds (P <0.10). This is the first known cross-sectional study of a population of urban northern Australian cats living in an affluent suburb and presenting saliva as a potential non-invasive sample for large-scale epidemiological surveys on FIV.
