Immunoglobulin M seroconversion to Ehrlichia chaffeensis was documented in U.S. citizens bitten by ticks in Sardinia. Seven cases of suspected ehrlichiosis in local residents were not confirmed by laboratory tests. In Alpine areas antibodies to E. phagocytophila were detected in persons at high risk, i.e., foresters (8.6%) and hunters (5.5%), and in controls (1.5%). Of 153 persons bitten by ticks, only one was Ehrlichia antibody-positive after 6 months.
在撒丁岛被蜱虫叮咬的美国公民中记录到了针对查菲埃立克体的免疫球蛋白M血清转化。当地居民中7例疑似埃立克体病病例未得到实验室检测的确认。在阿尔卑斯地区，在高危人群（即林业工人，占8.6%；猎人，占5.5%）以及对照组（占1.5%）中检测到了抗嗜吞噬细胞无形体抗体。在153名被蜱虫叮咬的人中，6个月后只有1人埃立克体抗体呈阳性。
