Studies investigating rickettsial infections in ticks parasitizing wild animals in the Northeast region of Brazil have been confined to the detection of Rickettsia amblyommii in immature stages of Amblyomma longirostre collected from birds in the state of Bahia, and in immatures and females of Amblyomma auricularium collected from the striped hog-nosed skunk (Conepatus semistriatus) and armadillos (Euphractus sexcinctus) in the state of Pernambuco. The current study extends the distribution of R. amblyommii (strain Aranha), which was detected in A. longirostre collected from the thin-spined porcupine Chaetomys subspinosus and the hairy dwarf porcupine Coendou insidiosus. In addition, we report the first detection of Rickettsia bellii in adults of A. longirostre collected from C. insidiosus in the state of Bahia.
对巴西东北部寄生于野生动物的蜱虫中rickettsial感染的研究,一直局限于在巴伊亚州从鸟类身上采集的长角血蜱未成熟阶段检测到安氏立克次体,以及在伯南布哥州从带纹猪鼻臭鼬(Conepatus semistriatus)和犰狳(Euphractus sexcinctus)身上采集的耳缘血蜱未成熟阶段和雌蜱中检测到安氏立克次体。当前研究扩展了安氏立克次体(Aranha菌株)的分布范围,该菌株在从细刺豪猪Chaetomys subspinosus和多毛矮豪猪Coendou insidiosus采集的长角血蜱中被检测到。此外,我们报告了在巴伊亚州从Coendou insidiosus采集的长角血蜱成虫中首次检测到贝利立克次体。
