1992年8月至1996年12月，在美国加利福尼亚北部沿海山麓地区收集了37只亚成年和成年土狼（Canis latrans），对其进行了成年心丝虫（Dirofilaria immitis）检测。1992年至1993年，在6年干旱结束时，检查的4只土狼中没有一只感染心丝虫。然而，在1994年至1996年期间，干旱结束后，23只成年土狼的患病率为91%，10只亚成年土狼的患病率为40%。心丝虫强度无性别差异，成虫平均（+/- SE） 19.4 +/- 3.8；一个亚成虫有bb0238条心虫。从1994年到1996年，这里报告的土狼心丝虫感染的流行率和强度是美国最高的。
Thirty-seven subadult and adult coyotes (Canis latrans), collected August 1992 through December 1996 from a coastal foothill area in northern California (USA), were examined for adult heartworm (Dirofilaria immitis). During 1992 through 1993, at the end of a 6 yr drought, none of four coyotes examined were infected with heartworms. However, during 1994 through 1996, after the drought had ended, prevalences were 91% in 23 adult coyotes and 40% in 10 subadult coyotes. Heartworm intensity did not differ by sex of coyote, and averaged (+/- SE) 19.4 +/- 3.8 among adults; one subadult had >238 heartworms. The prevalence and intensity of heartworm infection in coyotes reported here for 1994 through 1996 are the highest reported anywhere in the United States.
