Coxiella burnetii is a bacterium that causes coxiellosis in animals and Q fever in humans. While ruminants are the main reservoirs, the role of ticks in their transmission is still uncertain. This study looked for C. burnetii in ticks collected from two autochthonous breeds in Portugal: Churra Galega Mirandesa sheep and Garrano horses. A total of 555 ticks were tested, including 100 Rhipicephalus sanguineus sensu (s.) stricto (s.) from sheep and 455 Rhipicephalus bursa from horses. Coxiella burnetii was found in 7 % of R. sanguineus s.s., but not in R. bursa. Phylogenetic analysis confirmed the strains. These findings suggest that R. sanguineus s.s. may play a role in the bacterium's presence in livestock. Further research is needed to clarify the role of ticks in C. burnetii transmission in Portugal.
伯纳特柯克斯体是一种可导致动物患柯克斯体病和人类患Q热的细菌。虽然反刍动物是主要宿主，但蜱在其传播中的作用仍不确定。本研究在从葡萄牙两个本土品种采集的蜱中寻找伯纳特柯克斯体：查拉加莱加米兰德萨羊和加拉诺马。共检测了555只蜱，其中包括从羊身上采集的100只狭义血红扇头蜱和从马身上采集的455只柏氏扇头蜱。在7%的狭义血红扇头蜱中发现了伯纳特柯克斯体，但在柏氏扇头蜱中未发现。系统发育分析证实了这些菌株。这些发现表明，狭义血红扇头蜱可能在该细菌在牲畜中的存在中发挥作用。需要进一步研究以阐明蜱在葡萄牙伯纳特柯克斯体传播中的作用。
