Abstract
The purposes of this study were to determine the seroprevalence of feline leukemia virus (FeLV) and feline immunodeficiency virus (FIV) infection among cats in Canada and to identify risk factors for seropositivity. Signalment, lifestyle factors, and test results for FeLV antigen and FIV antibody were analyzed for 11 144 cats from the 10 Canadian provinces. Seroprevalence for FIV antibody was 4.3% and seroprevalence for FeLV antigen was 3.4%. Fifty-eight cats (0.5%) were seropositive for both viruses. Seroprevalence varied geographically. Factors such as age, gender, health status, and lifestyle were significantly associated with risk of FeLV and FIV seropositivity. The results suggest that cats in Canada are at risk of retrovirus infection and support current recommendations that the retrovirus status of all cats should be known.
摘要
本研究的目的是确定加拿大猫群中猫白血病病毒（FeLV）和猫免疫缺陷病毒（FIV）感染的血清阳性率，并确定血清阳性的风险因素。对来自加拿大10个省的11144只猫的信号特征、生活方式因素以及FeLV抗原和FIV抗体检测结果进行了分析。FIV抗体的血清阳性率为4.3%，FeLV抗原的血清阳性率为3.4%。58只猫（0.5%）两种病毒均呈血清阳性。血清阳性率存在地域差异。年龄、性别、健康状况和生活方式等因素与FeLV和FIV血清阳性风险显著相关。结果表明，加拿大的猫有感染逆转录病毒的风险，并支持目前关于应了解所有猫的逆转录病毒状态的建议。
