Prevalence rates of heartworm in coyotes was estimated for five northern California counties by examining hearts of coyotes obtained from federal or private trappers. Prevalence rates range from 8.3-27.3%, but the proportion of infected coyotes can vary between two regions of the same county. In general, it seems that higher infection rates are found in the foothill regions of the Coastal Range and Sierra Nevada, decreasing towards the floor of the Sacramento Valley as well as at higher elevations. The use of coyotes as sentinel animals for detecting natural foci of transmission is postulated.
通过检查从联邦或私人捕猎者处获得的郊狼心脏，对加利福尼亚州北部五个县的郊狼的心丝虫患病率进行了估算。患病率在8.3%至27.3%之间，但同一县的两个地区感染郊狼的比例可能有所不同。一般来说，沿海山脉和内华达山脉的山麓地区感染率较高，向萨克拉门托河谷谷底以及较高海拔地区递减。有人推测可将郊狼用作检测自然疫源地的哨兵动物。
