Mikrocytids are a widespread but rather neglected group of parasites of aquatic invertebrates. One such parasite is -discovered to infect the antennal gland of the juvenile edible crab, , taken from several intertidal sites across the United Kingdom. To determine if this parasite is also present in other species of decapod crustaceans, we surveyed crabs ( = 330) across two contrasting sites in Pembrokeshire (UK). Using a histopathological approach, infection was confirmed in variable numbers of edible crabs from both survey sites, 7%-44%. No measurable signs of infection were encountered in four other co-located species, including European shore crabs (), Montagu's crabs (), velvet swimming crabs () and broad-clawed porcelain crabs (). These data imply that has a more limited host range than suggested by molecular diagnosis alone.
微胞虫是一类广泛存在但却相当被忽视的水生无脊椎动物寄生虫。人们发现其中一种寄生虫感染了从英国各地潮间带采集的幼年食用蟹的触角腺。为了确定这种寄生虫是否也存在于其他十足目甲壳类动物物种中，我们在英国彭布罗克郡的两个不同地点对螃蟹（n = 330）进行了调查。采用组织病理学方法，在两个调查地点不同数量的食用蟹中证实了感染，感染率为7% - 44%。在其他四种同域分布的物种中未发现可测量的感染迹象，包括欧洲岸蟹、蒙塔古蟹、天鹅绒游泳蟹和宽爪瓷蟹。这些数据表明，仅通过分子诊断所显示的宿主范围比实际情况更为宽泛。
