ABSTRACT Boars are exotic animals in Brazil, which have bred with domestic pigs resulting in a hybrid known as “javaporco”. Both cause problems related to invasion of forests and farms. These animals are hosts of important tick species, which are vectors of zoonotic pathogens. The aim of this work was to identify ticks collected on these animals, as well as to screen these arthropods for pathogens they can transmit. In total, 29 hosts were evaluated for the presence of ticks by a group in charge of handling and controlling boars in Minas Gerais. The ticks collected were identified, the DNA was extracted, and PCR was performed for detection of Rickettsia, Babesia, Theileria, Borrelia, Ehrlichia, and Anaplasma. From 29 inspected animals, four (13.8%) were infested by ticks, which were identified as Amblyomma ovale and A. sculptum. Mean intensity and mean abundance for tick infestation were 1.5 and 0.2, respectively. PCR analyzes indicated no tick infection by the targeted pathogens. Due to the small number of collected specimens, further studies are needed to get results that are more reliable. The genus Amblyomma parasitizes “javaporcos” and these results are of great importance since both tick species herein identified are vectors of zoonotic pathogens.

巴西米纳斯吉拉斯州寄生野猪的Amblyomma蜱（Acari：Ixodidae）

摘要 公猪是巴西的外来动物，它们与家猪一起繁殖，产生了一种被称为“javaporco”的杂种。两者都会引起与入侵森林和农场有关的问题。这些动物是重要蜱种的宿主，蜱是人畜共患病原体的载体。这项工作的目的是识别收集在这些动物身上的蜱，并筛选这些节肢动物可以传播的病原体。在米纳斯吉拉斯州，一个负责处理和控制公猪的小组总共评估了 29 名寄主是否存在蜱虫。对采集的蜱进行鉴定，提取DNA，并进行PCR检测立克次体、巴贝斯体、泰勒虫、疏螺旋体、埃立克体和无形体。在接受检查的 29 只动物中，有 4 只 (13.8%) 被蜱虫侵染，被确定为椭圆形Amblyomma 和A. sculptum。蜱侵染的平均强度和平均丰度分别为 1.5 和 0.2。PCR 分析表明目标病原体没有蜱感染。由于采集的标本数量较少，需要进一步研究以获得更可靠的结果。Amblyomma 属寄生于“javaporcos”，这些结果非常重要，因为本文鉴定的两种蜱种都是人畜共患病原体的载体。
