We determined the prevalence of Dirofilaria immitis (Nematoda, Filariidae) among 433 red foxes (Vulpes vulpes) in northeastern Spain, between 1990 and 1992. Forty-six (11%) of 433 foxes were infected; the intensity ranged from 1 to 36 (mean +/- SE; 4.39 +/- 0.92) nematodes per host. The prevalence of D. immitis was higher in foxes inhabiting riparian zones of the study area. This population has a very high juvenile/adult ratio. Heartworm prevalences did not differ among host sex, weight, or fat condition categories.
1990年至1992年间，我们在西班牙东北部的433只赤狐（赤狐属）中确定了犬恶丝虫（线虫纲，丝虫科）的流行情况。433只狐狸中有46只（11%）被感染；感染强度为每只宿主1至36条线虫（平均值±标准误；4.39±0.92）。在研究区域河岸带栖息的狐狸中，犬恶丝虫的流行率更高。该种群的幼体/成体比例非常高。宿主的性别、体重或脂肪状况类别之间的心丝虫流行率没有差异。
