Ixodes ricinus and Dermacentor reticulatus ticks were collected by flagging from the vegetation at five different locations in Poland in May 1994. I. ricinus (n191) and D. reticulatus (n48), as well as 24 Argas reflexus collected from Katowice, Kornie, Szcyglice, Urwitałt and Zwierzyniec, were examined for the presence of Borrelia spirochetes by the indirect immunofluorescent antibody test (IFA). Borrelia were found in adult I. ricinus ticks at all 5 collection sites. Nine out of 39 I. ricinus males (23%) and 16 out of 72 I. ricinus females (22.2%) were infected. In addition, 2 out of 72 I. ricinus larvae (2.7%) were heavily infected, whereas none of the D. reticulatus and A. reflexus contained Borrelia. These results show that I. ricinus is also in Poland the main vector of Lyme disease-causing spirochetes. The finding that some larvae are also infected merits further investigations into the relative role of transovarial transmission of Borrelia in field populations of I. ricinus ticks.
1994年5月，通过在波兰五个不同地点的植被上进行拖旗法采集蓖麻硬蜱和网纹革蜱。对191只蓖麻硬蜱、48只网纹革蜱以及从卡托维兹、科尔涅、什奇格利采、乌尔维塔尔特和兹维列涅茨采集的24只波斯锐缘蜱进行间接免疫荧光抗体试验（IFA），检测伯氏疏螺旋体的存在情况。在所有5个采集地点的成年蓖麻硬蜱中均发现了伯氏疏螺旋体。39只蓖麻硬蜱雄蜱中有9只（23%）被感染，72只蓖麻硬蜱雌蜱中有16只（22.2%）被感染。此外，72只蓖麻硬蜱幼虫中有2只（2.7%）感染严重，而网纹革蜱和波斯锐缘蜱均未检测到伯氏疏螺旋体。这些结果表明，在波兰，蓖麻硬蜱也是导致莱姆病的螺旋体的主要传播媒介。一些幼虫也被感染这一发现值得进一步研究伯氏疏螺旋体经卵传播在蓖麻硬蜱野外种群中的相对作用。
