Tick-borne pathogens belong to one of the two main groups of occupational biohazards, and occupational exposure to such agents puts soldiers at risk of zoonotic infections, such as those caused by rickettsiae. There are few studies on acarological fauna and occupational risk in military areas in Brazil. Thus, the present study aimed to analyze the diversity of ticks present in the military training areas of municipalities in the Southeast Region of Brazil. The ticks were collected from the selected areas using the dragging and flagging techniques as well as by visual detection on the operators' clothing, and environmental information was also recorded. A total of ten species were collected from the 66 surveyed areas, belonging to five genera and nine species: Amblyomma sculptum, Amblyomma dubitatum, Amblyomma brasiliense, Amblyomma longirostre, Amblyomma aureolatum, Dermacentor nitens, Rhipicephalus spp., Ixodes spp. and Haemaphysalis spp. The frequent presence of tick species in military training areas along with traces and sightings of wild animals, most commonly capybaras (Hydrochoerus hydrochaeris), in most of the studied areas, indicates high levels of exposure of the military to tick vectors of spotted fever group rickettsiae and the possible occurrence of infections among the troops.
蜱传病原体属于职业性生物危害的两个主要类别之一，职业性接触此类病原体可使士兵面临动物源感染的风险，如立克次体引起的感染。巴西军事区域的节肢动物区系和职业风险研究较少。因此，本研究旨在分析巴西东南部军事训练区的蜱类多样性。使用拖拽和标记技术以及在操作人员的衣物上通过视觉检测收集选定区域的蜱虫，并记录环境信息。从调查的 66 个区域共收集到 10 种蜱虫，属于 5 个属和 9 个种：刻点钝缘蜱、边缘钝缘蜱、巴西钝缘蜱、长角血蜱、金黄扇头蜱、璃眼蜱属、革节蜱属、全沟硬蜱属和扇头蜱属。在军事训练区经常发现蜱虫，并且在大多数研究区域都有野生动物的踪迹和目击，最常见的是水豚（Hydrochoerus hydrochaeris），这表明军人接触斑点热群立克次体的蜱虫媒介的风险很高，部队中可能发生感染。
