Lesions due to Dracunculus insignis in the legs of raccoons (Procyon lotor) in southern Ontario occur seasonally as most larvigerous females emerge in the spring and early summer (April-June). The pathology of dracunculiasis in the raccoon is described and the transmission of the parasite in the wild is discussed with respect to seasonality and local agricultural practices. Crayfish, fishes and frogs (including tadpoles) were given infective third-stage larvae of D. insignis to test their suitability as paratenic hosts. Most of the larvae fed to adult Rana pipiens and R. clamitans were recovered from the somatic musculature. Larvae had increased in size and were highly infective to raccoons.
安大略省南部浣熊（北美浣熊）腿部因微小麦地那龙线虫引起的病变具有季节性，因为大多数携带幼虫的雌虫在春季和初夏（4月至6月）出现。本文描述了浣熊麦地那龙线虫病的病理学，并就寄生虫在野外的传播的季节性和当地农业实践进行了讨论。将微小麦地那龙线虫感染性三期幼虫投喂给小龙虾、鱼类和青蛙（包括蝌蚪），以测试它们作为转续宿主的适宜性。投喂给成年美国牛蛙和绿蛙的大多数幼虫都在体壁肌肉中被发现。幼虫体积增大，对浣熊具有高度感染性。
