The aims of this study were to carry out a serological survey of canine leishmaniasis and identify the phlebotomine fauna in the urban area of Bonito, Mato Grosso do Sul. The serological survey was conducted on a sample of 303 dogs, by means of the indirect immunofluorescence test. Phlebotomines were captured using automated light traps. The serological survey found that 30% of the dogs were seropositive, both from the center and from all districts of the town. A total of 2,772 specimens of phlebotomines were caught and the species most found was Lutzomyia longipalpis (90.4%), which corroborated its role as the vector of for canine visceral leishmaniasis in the region. Phlebotomines of the species Bichromomyia flaviscutellata (the main vector for Leishmania (Leishmania) amazonensis) and Nyssomyia whitmani (the vector for Leishmania (Viannia) brasiliensis) were also caught. The findings indicate the need for continuous epidemiological surveillance, with attention towards diminishing the vector breeding sites and the transmission of these diseases in that region.
本研究的目的是对巴西南马托格罗索州博尼托市的犬利什曼病进行血清学调查,并鉴定其白蛉种类。通过间接免疫荧光试验对 303 只狗进行了血清学调查。使用自动诱虫灯捕获白蛉。血清学调查发现,30%的狗呈血清阳性,无论是来自市中心还是来自该镇的所有区。共捕获了 2772 只白蛉,其中最常见的物种是长角血蝉(90.4%),这证实了它在该地区作为犬内脏利什曼病传播媒介的作用。还捕获了 Bichromomyia flaviscutellata 种(主要传播媒介为 Leishmania (Leishmania) amazonensis)和 Nyssomyia whitmani 种(传播媒介为 Leishmania (Viannia) brasiliensis)的白蛉。这些发现表明需要进行持续的流行病学监测,重点是减少传播媒介的滋生地,并减少该地区这些疾病的传播。
