Abstract:
Here, we described the prevalence of Borrelia burgdorferi s.l. and Babesia species found in mono- and double infections among Ixodes ricinus ticks occurring in urban areas of the city of Poznań, Poland. We tested 1029 host-seeking ticks and 1268 engorged ticks removed from pet animals. Borrelia afzelii and B. garinii prevailed both in ticks from vegetation (3.7% and 3.7%, respectively) and from pets (3.7% and 0.6%, respectively). Babesia canis and Ba. microti were the most prevalent in host-seeking (2.6% and 1.4%, respectively) and feeding ticks (2.8% and 2.2%, respectively). Babesia microti sequences proved to be identical to the human pathogenic Ba. microti genotype \"Jena/Germany\". Sequences of the rarest piroplasm Ba. venatorum (0.7%) were identical with those isolated from European patients. About 1.0% of tested ticks yielded dual infections; in host-seeking ticks, Ba. canis prevailed in co-infections with B. afzelii and B. garinii, whereas Ba. microti and B. afzelii dominated in double-infected feeding ticks. Dual infections, even with a low prevalence, pose a challenge for differential diagnosis in patients with acute febrile disease after a tick bite. The finding of Ba. canis in both tick groups suggests that I. ricinus could be involved in the circulation of this piroplasm.
摘要:
这里,我们描述了伯氏螺旋体的患病率。在波兹南市城市地区的蓖麻蜱中,在单感染和双感染中发现了巴贝虫物种,波兰。我们测试了从宠物动物身上取出的1029个寻求寄主的蜱和1268个充血的蜱。非螺旋体和B.garinii在植被中都占主导地位(分别为3.7%和3.7%,分别)和宠物(3.7%和0.6%,分别)。犬巴贝虫和巴。microti在寻找宿主中最普遍(2.6%和1.4%,分别)和喂食蜱(2.8%和2.2%,分别)。被证明与人类致病性Ba相同的Babesiamicroti序列。microti基因型\“耶拿/德国”。最稀有的梨质Ba的序列。venatorum(0.7%)与从欧洲患者中分离的患者相同。约1.0%的测试壁虱产生双重感染;在寻求宿主的壁虱中,巴。canis普遍存在于与阿夫泽利B.和加里尼B.的共同感染中,而Ba。microti和B.afzelii在双重感染的饲养蜱中占主导地位。双重感染,即使患病率很低,对蜱叮咬后急性发热病患者的鉴别诊断提出了挑战。Ba的发现。两个tick组的犬都表明,蓖麻可能参与了这种pirogra的循环。
