Ehrlichia spp. are a group of intracellular parasitic bacteria primarily transmitted by ticks. They exhibit a wide global distribution and can infect a diverse range of mammals, including humans, underscoring their immense public health significance.
Among 631 ticks examined, all were identified as belonging to the Rhipicephalus linnaei; of these, 63 (9.98%) out of 631 ticks tested positive for Ehrlichia canis.Additionally, 140 (11.08%) out of 1264 dog blood samples were positive for E. canis. Notably, Ehrlichia ewingii and Ehrlichia chaffeensis were not detected. The prevalence of Ehrlichia infection in dogs was associated with factors such as age, breed, dewormer use, tick infestation, and living environment while displaying no association with the dog's gender.
In Hainan Province, Rhipicephalus linnaei is the dominant tick species infecting dogs. Dogs are vulnerable to Ehrlichia infection, particularly rural and stray dogs, suggesting the need for a targeted control strategy.
埃立克体属是一类主要通过蜱传播的细胞内寄生细菌。它们在全球广泛分布,可感染包括人类在内的多种哺乳动物,凸显了其巨大的公共卫生意义。
在检查的631只蜱中,所有蜱均被鉴定为属于里氏扇头蜱;其中,631只蜱中有63只(9.98%)检测出犬埃立克体呈阳性。此外,在1264份犬血样中,有140份(11.08%)犬埃立克体呈阳性。值得注意的是,未检测到尤因埃立克体和查菲埃立克体。犬类中埃立克体感染的患病率与年龄、品种、驱虫药使用、蜱虫感染和生活环境等因素有关,而与犬的性别无关。
在海南省,里氏扇头蜱是感染犬类的主要蜱种。犬类易感染埃立克体,尤其是农村犬和流浪犬,这表明需要制定有针对性的控制策略。
