In Maio Island, Republic of Cape Verde, a seven-year old mongrel female dog exhibiting severe generalized adenomegaly and a poor body condition was examined during an animal welfare campaign. A blood smear was drawn from peripheral blood collection and several organisms consistent with Dirofilaria immitis microfilariae were identified. Both the antigen test conducted from plasma and the RT-PCR test performed from the blood smear sample were positive for D. immitis. This is, to the best of our knowledge, the first report of D. immitis in Cape Verde. The fact that the dog was autochthonous and had never left the island strongly suggests there might be other animals infected with the parasite. Our finding confirms the existence of the parasite in the canine population and necessarily implies the presence of a competent vector. As a serious cardiopulmonary disease and with the risk of the pathogen spreading rapidly, broader epidemiological studies need to be conducted to determine D. immitis prevalence in the canine population of Maio Island.
在佛得角共和国的马约岛，一场动物福利活动中检查了一只七岁的杂种母狗，它表现出严重的全身性腺瘤和身体状况不佳。从外周血采集处抽取了血涂片，发现了几种与犬恶丝虫微丝蚴一致的生物体。来自血浆的抗原检测和血液涂片样本的 RT-PCR 检测均对犬恶丝虫呈阳性。据我们所知，这是佛得角首次报告犬恶丝虫。该狗是土生土长的，从未离开过该岛，这强烈表明可能还有其他动物感染了寄生虫。我们的发现证实了寄生虫在犬群中的存在，必然意味着存在有能力的传播媒介。由于这是一种严重的心肺疾病，且病原体有迅速传播的风险，因此需要进行更广泛的流行病学研究，以确定马约岛犬群中犬恶丝虫的流行率。
