To determine prevalence of FeLV infection and serum antibodies against feline immunodeficiency virus (FIV) in unowned free-roaming cats.
Cross-sectional serologic survey.
733 unowned free-roaming cats in Raleigh, NC, and 1,143 unowned free-roaming cats in Gainesville, Fla.
In Raleigh, overall prevalence of FeLV infection was 5.3%, and overall seroprevalence for FIV was 2.3%. In Gainesville, overall prevalence of FeLV infection was 3.7%, and overall seroprevalence for FIV was 4.3%. Overall, FeLV prevalence was 4.3%, and seroprevalence for FIV was 3.5%. Prevalence of FeLV infection was not significantly different between males (4.9%) and females (3.8%), although seroprevalence for FIV was significantly higher in male cats (6.3%) than in female cats (1.5%).
Prevalence of FeLV infection and seroprevalence for FIV in unowned free-roaming cats in Raleigh and Gainesville are similar to prevalence rates reported for owned cats in the United States. Male cats are at increased risk for exposure to FIV, compared with female cats.
确定无主自由放养猫中猫白血病病毒（FeLV）感染率及抗猫免疫缺陷病毒（FIV）血清抗体情况。
横断面血清学调查。
北卡罗来纳州罗利市的733只无主自由放养猫以及佛罗里达州盖恩斯维尔市的1143只无主自由放养猫。
在罗利市，FeLV总体感染率为5.3%，FIV总体血清阳性率为2.3%。在盖恩斯维尔市，FeLV总体感染率为3.7%，FIV总体血清阳性率为4.3%。总体而言，FeLV感染率为4.3%，FIV血清阳性率为3.5%。FeLV感染率在雄性猫（4.9%）和雌性猫（3.8%）之间无显著差异，不过FIV血清阳性率在雄性猫（6.3%）中显著高于雌性猫（1.5%）。
罗利市和盖恩斯维尔市无主自由放养猫中FeLV感染率及FIV血清阳性率与美国有主猫的报告患病率相似。与雌性猫相比，雄性猫接触FIV的风险更高。
