非法废物处置为啮齿动物及其体外寄生虫提供了庇护所，是病媒传播疾病的一个健康风险因素。在位于突尼斯中部流行地区村庄附近的非法废物场所，对人畜共患皮肤利什曼病（ZCL）的病原体-利什曼原虫的Papatasi白蛉载体的存在进行了评估。该研究在2017年7月至9月的三个晚上和2018年9月的三个晚上进行了为期两年的研究。生活垃圾被非法堆放，在每个村庄附近形成垃圾场，并含有几个沙鼠的啮齿动物洞穴，沙鼠是沙鼠的主要宿主。少校白蛉收集啮齿动物洞穴中的自然环境和垃圾场使用粘性陷阱，并确定在物种水平。雌性白蛉进行了L。主要是PCR。我们的昆虫学调查表明，Phlebotomus papatasi是最丰富的白蛉物种与啮齿动物洞穴在这些废物的网站。与自然环境相比，垃圾场中的P. papatasi密度明显较高。番木瓜疫霉对L.主要是在这些非法废物的网站是没有显着不同的自然环境相比。考虑到帕帕塔斯的短飞行距离，其密度的增加，与位于村庄边缘的非法废物场的P. obesus洞穴相关，扩大了感染ZCL载体与社区的重叠。因此，非法废物场造成ZCL传播到邻近家庭范围的高风险。废物管理是控制白蛉种群的一种环境友好的方法，应纳入流行国家控制ZCL的综合管理计划。
Illegal waste disposal represents a risk health factor for vector-borne diseases by providing shelter for rodents and their ectoparasites. The presence of the Phlebotomus papatasi vector of Leishmania major, an etiologic agent of zoonotic cutaneous leishmaniasis (ZCL), was assessed at illegal waste sites located at the vicinity of villages in endemic areas of Central Tunisia. The study was performed over a two-year period over three nights from July to September 2017, and over three nights in September 2018. Household waste is deposited illegally forming dumpsites at the vicinity of each village and contains several rodent burrows of Psammomys obesus, the main reservoir host of L. major. Sandflies were collected from rodent burrows in the natural environment and in dumpsites using sticky traps and were identified at species level. Female sandflies were tested for the presence of L. major by PCR. Our entomological survey showed that Phlebotomus papatasi is the most abundant sandfly species associated with rodent burrows in these waste sites. The densities of P. papatasi in dumpsites are significantly higher compared to the natural environment. The minimum infection rate of P. papatasi with L. major in these illegal waste sites is not significantly different compared to the natural environment. Considering the short flight range of P. papatasi, increases in its densities, associated with burrows of P. obesus in illegal waste sites located at the edge of villages, expands the overlap of infected ZCL vectors with communities. Thus, illegal waste sites pose a high risk of spreading ZCL to neighboring home ranges. Waste management is an environmentally friendly method of controlling sandfly populations and should be included in an integrated management program for controlling ZCL in endemic countries.
