This paper reports the presence of various species of filarial nematodes in dogs in an area of central Italy at the border between two regions (Tuscany-Latium), which had previously been free of infection and for which there are no epidemiological data in the literature. Blood and serum samples from a total of 363 adult dogs were collected during in 2016/17 and 2018/19 in the provinces of Grosseto (Tuscany) and Viterbo (Latium). The dogs were of different breeds or mixed breeds, randomly selected, and living in public kennels or privately owned. Of the 363 samples tested, 55 dogs were positive to Knott's test for microfilariae (prevalence 15.1%; 95% confidence interval: 11.5-18.8%). Dirofilaria immitis was found in 25 cases (prevalence 6.9%; 95% CI 4.3-9.5%), D. repens in 27 (7.4%, 95% CI 4.7-10.1%) and Acanthocheilonema reconditum in 3 (0.8%, 95% CI 0.1-1.7%). Out of 55 dogs, only four were infested with both D. immitis and D. repens (1.1%, 95% CI 0.001-2.2%).
本文报告了在意大利中部两个地区（托斯卡纳-拉齐奥）边界地区的犬类中存在多种丝虫线虫。该地区以前没有感染病例，文献中也没有相关的流行病学数据。在 2016/17 年和 2018/19 年期间，总共从 363 只成年犬身上采集了血液和血清样本，这些犬来自格罗塞托（托斯卡纳）和维泰博（拉齐奥）两省的公共犬舍或私人饲养。这些犬是不同品种或混血犬，随机选择，生活在公共犬舍或私人饲养。在检测的 363 个样本中，有 55 个犬只对微丝蚴的 Knott 检测呈阳性（患病率为 15.1%；95%置信区间：11.5-18.8%）。在 25 例中发现了犬恶丝虫（患病率为 6.9%；95%CI 4.3-9.5%），在 27 例中发现了犬复孔绦虫（患病率为 7.4%；95%CI 4.7-10.1%），在 3 例中发现了细颈线虫（患病率为 0.8%；95%CI 0.1-1.7%）。在 55 只犬中，只有 4 只同时感染了犬恶丝虫和犬复孔绦虫（1.1%；95%CI 0.001-2.2%）。
