为了确定野生小鼠中潜在的人类致病性微孢子虫（bieneusenterocytozoon and Encephalitozoon spp.）的发生率，我们在捷克-德国边境地区的74个地点捕获了289只东欧家鼠（musculus musus）和西欧家鼠（M. M. domesticus）。在33个地方检测到小孢子虫，在34%的肌肉支原体和33%的家养支原体检测标本中检测到。单种感染小鼠分别为hellem E. 23只、cucululi E. 42只和bieneusi E. 25只。未检出肠囊虫阳性动物。共感染6只；在3只小鼠中，布氏埃希菌与库氏埃希菌或赫勒姆埃希菌共存。hellem在小鼠中的自然感染从未有过记录。对家鼠亚种间小孢子虫发生情况进行统计分析，未发现差异。虽然小孢子虫的性别依赖性侵染在统计上得到了支持，但当估计所有雄性和雌性的小孢子虫发生时，无论家鼠亚种，都没有观察到显著差异。本报告的结果证明了检测到的微孢子虫物种的低宿主特异性，并暗示了合群啮齿动物作为人类微孢子虫感染的潜在来源的重要性。(C) 2011 Elsevier B.V.版权所有
To determine the occurrence of potentially human pathogenic microsporidia (Enterocytozoon bieneusi and Encephalitozoon spp.) in wild mice, we examined 289 East-European House Mice (Mus musculus musculus) and West-European House Mice (M. m. domesticus) trapped at 74 localities in an area across the Czech-German border. Microsporidia were detected at 33 localities, in 34% of M. m. musculus and 33% of M. m. domesticus examined specimens. Single-species infection was detected in 23 mice for E. hellem, 42 mice for E. cuniculi and 25 mice for E. bieneusi. No Encephalitozoon intestinalis positive animals were identified. Moreover, co-infections were detected in 6 animals; E. bieneusi co-existed with E. cuniculi or E. hellem in 3 mice. The natural infection of E. hellem has never been recorded in mice before. No differences were found by a statistical analysis of microsporidia occurrence between the House Mouse subspecies. Although the gender-dependent infestation of microsporidia was statistically supported in M. m. musculus, no significant differences were observed when the occurrence of microsporidia was estimated for all males and females irrespective of the House Mouse subspecies. The results of this report document the low host specificity of detected microsporidia species and imply the importance of synanthropic rodents as a potential source of human microsporidial infection.
