It had been previously noticed that infection with parasites was common in children suffering from phlyctenulosis. In the present study the stools of 471 patients suffering from phlyctenular disease were examined and it was found that 62.6% of them had Hymenolepis nana ova in their stools as compared with 10.8% of the controls. All patients had Hymenolipis nana immune sera. Many of these patients had abdominal symptoms. Hymenolepis nana is a cestode parasite discovered by Bilharz in Cairo in 1851. Infections with it have the same age incidence and geographical distribution as phlyctenular eye disease. It has a tissue stage responsible for a state of hypersensitivity which is thought to be responsible for the phlyctenules.
此前已经注意到，患有泡性角结膜炎的儿童中寄生虫感染很常见。在本研究中，对471例泡性疾病患者的粪便进行了检查，发现其中62.6%的患者粪便中有微小膜壳绦虫卵，而对照组的这一比例为10.8%。所有患者都有微小膜壳绦虫免疫血清。这些患者中有许多有腹部症状。微小膜壳绦虫是1851年比尔哈兹在开罗发现的一种绦虫寄生虫。其感染与泡性眼病具有相同的年龄发病率和地理分布。它有一个组织阶段，会导致一种超敏反应状态，这种超敏反应被认为是泡性小泡形成的原因。
