The purpose of this study was to estimate the apparent prevalence and identify risk factors for antibody levels (AL) against canine distemper virus (CDV), canine parvovirus (CPV), and canine adenovirus (CAV) in three communities in the metropolitan area of Quito, Ecuador that have limited access to regular veterinary care. Whole blood samples were collected from 154 dogs presenting to three veterinary field clinics in mainland Ecuador and tested for AL against CDV, CPV, and CAV by a commercially available point-of-care ELISA. Potential risk factors for the presence of AL were analyzed. A majority of dogs had AL against CDV (66%, 95% CI = 58-73%), CPV (95%, 95% CI = 91-98%) and CAV (60%, 95% CI = 52-67%). Dogs had significantly greater odds of AL against CDV if they were >2 years of age, from an urban community, and had previously received veterinary care. Dogs had significantly greater odds of AL against CAV if they were male, >2 years of age, and had previously received veterinary care. Results provide baseline estimates of AL within each community and allow for the targeting of future veterinary services to communities and dogs most at risk.

厄瓜多尔大陆社区中存在针对犬瘟热，犬细小病毒和犬腺病毒的血清抗体的患病率和危险因素。

这项研究的目的是评估基多都会区三个社区的犬瘟热病毒（CDV），犬细小病毒（CPV）和犬腺病毒（CAV）的明显流行程度并确定抗体水平（AL）的危险因素，厄瓜多尔无法获得定期的兽医护理。从提供给厄瓜多尔大陆的三个兽医现场诊所的154只狗中收集全血样品，并通过市售的即时诊断ELISA检测针对CDV，CPV和CAV的AL。分析了存在AL的潜在危险因素。大多数狗对CDV的AL（66％，95％CI = 58-73％），CPV（95％，95％CI = 91-98％）和CAV（60％，95％CI = 52-67％） ）。如果来自城市社区的狗大于2岁，则其患CDV的AL几率要高得多，并且以前接受过兽医护理。如果狗是雄性，> 2岁且以前接受过兽医护理，则其患CAV的AL几率要高得多。结果提供了每个社区内AL的基线估计值，并可以将未来的兽医服务针对的社区和风险最高的狗作为目标。
