Ticks Tick Borne Dis. 2019 Jan;10(1):77-85. doi: 10.1016/j.ttbdis.2018.09.003. Epub 2018 Sep 11.
In this study, we examine the current pattern of tick diversity and host use in French Guiana, South America, from 97 sampling localities encompassing peri-urban, rural and natural habitats. We collected 3395 ticks, including 1485 specimens from 45 vertebrate species (humans, domestic and wild animals) and 1910 questing specimens from vegetation. Morphological examinations identified 22 species belonging to six genera: Amblyomma (16 species), Rhipicephalus (two species), Ixodes (one species), Dermacentor (one species), Haemaphysalis (one species), Ornithodoros (one species). To facilitate future identification, we produced a bank of pictures of different stages for all these species. Taxonomic identification was then confirmed by molecular characterization of two mitochondrial genes, cytochrome c oxidase CO1 and 16S rDNA. Eleven of the 22 reported species were collected on humans, six on domestic animals and 12 on wild animals. The most widespread tick species collected were A. cajennense sensu stricto and, to a lesser extent, A. oblongoguttatum; both of these species were frequently found on humans. We used these results to discuss the tick-associated risks for human and animal health in French Guiana.
在这项研究中，我们检查了来自南美洲法属圭亚那的 97 个采样地点的当前蜱虫多样性和宿主利用模式，这些采样地点包括城市周边、农村和自然栖息地。我们收集了 3395 只蜱虫，其中包括 1485 只来自 45 种脊椎动物（人类、家养和野生动物）的标本和 1910 只来自植被的游离蜱标本。形态学检查鉴定出属于六个属的 22 种：硬蜱属（16 种）、璃眼蜱属（2 种）、革蜱属（1 种）、扇头蜱属（1 种）、血蜱属（1 种）、钝缘蜱属（1 种）。为了便于今后的鉴定，我们为所有这些物种制作了不同发育阶段的图片库。然后通过两个线粒体基因（细胞色素 c 氧化酶 CO1 和 16S rDNA）的分子特征来确认分类学鉴定。报告的 22 种中有 11 种在人类身上采集，6 种在家畜上采集，12 种在野生动物上采集。采集到的最广泛的蜱种是严格意义上的 A. cajennense sensu stricto，以及在较小程度上的 A. oblongoguttatum；这两种物种都经常在人类身上发现。我们利用这些结果讨论了法属圭亚那人与动物健康相关的蜱虫风险。
