为了确定非致病性螺质体的存在是否会混淆现场估计的微小巴贝虫感染风险，我们通过平行显微镜和聚合酶链反应测定鉴定了感染鹿蜱（Ixodes dammini）唾液腺的孢子虫。美国中北部和东北部地区14.4%的成年蜱中有明显的梨形虫。其中83.3%含有Ba特征DNA。odocoilei。在所有检查的部位都检测到这种子宫颈卟啉质，并且通常比Ba更普遍。microti。因为鹿蜱会传播Ba。奥多科莱和巴。单纯依靠显微镜对病原体流行率的估计可能高估了人类巴贝斯虫病的风险。
To determine whether the presence of nonpathogenic piroplasms may confound field estimates of risk of Babesia microti infection, we identified sporozoites infecting the salivary glands of deer ticks (Ixodes dammini) by parallel microscopy and polymerase chain reaction assays. Piroplasms were evident in 14.4% of adult ticks from sites in the northcentral and northeastern United States. Of these, 83.3% contained DNA characteristic of Ba. odocoilei. This cervid piroplasm was detected in all of the sites examined and generally was more prevalent than was Ba. microti. Because deer ticks transmit both Ba. odocoilei and Ba. microti, estimates of pathogen prevalence based solely on microscopy may overestimate the risk of human babesiosis.
