Leishmaniosis, dirofilariosis and angiostrongylosis are parasitic diseases of established importance in dogs worldwide. The aim of the present report was to determine all together levels of infection with or exposure to Leishmania infantum, Dirofilaria immitis and Angiostrongylus vasorum in dogs from the Algarve region, in southern Portugal.
Serum samples were obtained from a total of 170 apparently healthy dogs. Antibodies to L. infantum were detected by the direct agglutination test; and antigens of D. immitis and of A. vasorum by an enzyme-linked immunosorbent assay and an immunochromatography test, respectively. Antibodies to L. infantum were found in 18.2% (31/170) of dogs, while D. immitis antigen was detected in 9.4% (16/170). None of 120 dogs tested out of the 170 under investigation had evidence of infection with A. vasorum. D. immitis infection was more prevalent in dogs aged 84-204 months than in those younger than 12 months. Three dogs were positive to both L. infantum and D. immitis.
Dogs living in southern Portugal are at risk of leishmaniosis and dirofilariosis. This scenario should make the veterinary community, local dog owners and also tourists from non-endemic countries coming on vacation with their pets aware of the need of effective prophylactic measures, in order to protect animals and public health.
利什曼病、恶丝虫病和血管圆线虫病是在全球范围内对犬类具有既定重要性的寄生虫病。本报告的目的是共同确定葡萄牙南部阿尔加维地区犬类感染婴儿利什曼原虫、犬恶丝虫和血管圆线虫或接触这些病原体的水平。
从总共170只看似健康的犬只采集血清样本。通过直接凝集试验检测婴儿利什曼原虫抗体；分别通过酶联免疫吸附测定和免疫层析试验检测犬恶丝虫和血管圆线虫抗原。在18.2%（31/170）的犬只中发现了婴儿利什曼原虫抗体，而在9.4%（16/170）的犬只中检测到犬恶丝虫抗原。在接受检测的170只犬中的120只中，没有一只显示有血管圆线虫感染的证据。犬恶丝虫感染在84 - 204月龄的犬中比在12月龄以下的犬中更普遍。有3只犬对婴儿利什曼原虫和犬恶丝虫均呈阳性。
生活在葡萄牙南部的犬有感染利什曼病和恶丝虫病的风险。这种情况应使兽医界、当地犬主以及来自非流行国家带着宠物度假的游客意识到需要采取有效的预防措施，以保护动物和公众健康。
