Abstract：
Extra-enteric infections by Blastocystis spp. have rarely been documented. Here, we report a case of extra-enteric blastocystosis in a patient with minimal cervicitis symptoms. A 47-year-old Hispanic female patient was attended in a primary health centre in Michoacan state, Mexico, for her routine gynaecological medical examination. As only symptom, she referred to a slight vaginal itching. The presence of several vacuolar-stages of Blastocystis spp. were identified by Papanicolaou staining; molecular identification was attempted by culture-PCR sequencing of a region of 18S gene from cervical and faecal samples obtained 2 months after cytological examination, even when patient declared that she tried self-medicating with vaginal ovules. Blastocystis ST1 was identified only in the faecal sample. The presence of Blastocystis spp. in the cervix of a patient with scarce symptomatology, demonstrates the extraordinary flexibility of this microorganism to adapt to new environments and niches.
摘要：
囊胚菌属的肠外感染。很少被记录在案。这里,我们报告了1例肠外囊胚形成的病例，患者的症状轻微的宫颈炎。一名47岁的西班牙裔女性患者在米却肯州的初级保健中心接受了治疗，墨西哥,她的常规妇科体检.作为唯一的症状，她指的是轻微的阴道瘙痒。囊胚属的几个液泡阶段的存在。通过Papanicolaou染色鉴定；通过对细胞学检查2个月后获得的宫颈和粪便样品中的18S基因区域进行培养-PCR测序，尝试进行分子鉴定，即使当患者宣布她尝试用阴道胚珠自我治疗时。仅在粪便样品中鉴定出囊胚ST1。囊胚的存在。在症状稀少的患者的子宫颈中，展示了这种微生物适应新环境和生态位的非凡灵活性。
