Schistosoma mekongi, a parasite of the dog which is endemic in small foci along the Mikong river, is rarely seen in Europe. A case of schistosomiasis caused by S mekongi was recently seen in France, in a native of Laos who had been living in Thailand. He was admitted for treatment of previous diagnosed tuberculoid leprosy but was found to have hepatosplenomegaly, with a high eosinophil count and high bilirubin concentrations. Serological examination suggested schistosomiasis, but there were no parasites in the urine and the rectal mucosa looked normal on endoscopy. Nevertheless, rectal biopsy showed schistosomal proctitis and many ova of S mekongi. Two courses of praziquantel cleared the ova from his rectal mucosa. Although serological examination using S mansoni antigen suggested schistosomiasis, only biopsy of normal looking rectal mucosa allowed the diagnosis to established.
湄公血吸虫是一种寄生于犬类的寄生虫，在湄公河沿岸的小范围内呈地方性流行，在欧洲很少见。最近在法国发现了一例由湄公血吸虫引起的血吸虫病病例，患者是一名曾居住在泰国的老挝人。他因先前诊断出的结核样麻风病入院治疗，但发现有肝脾肿大、嗜酸性粒细胞计数高和胆红素浓度高的情况。血清学检查提示血吸虫病，但尿液中未发现寄生虫，内镜检查时直肠黏膜看起来正常。然而，直肠活检显示为血吸虫性直肠炎，并发现了许多湄公血吸虫卵。两疗程的吡喹酮清除了他直肠黏膜中的虫卵。尽管使用曼氏血吸虫抗原进行的血清学检查提示血吸虫病，但只有对看似正常的直肠黏膜进行活检才能确诊。
