O. gibsoni worms were extracted from 185 nodules of a total of 370 worm nodules collected from 94 naturally infected cattle at Townsville, Australia. 183 of the 185 nodules contained a single female worm, 60% of them contained a single male worm and 7% contained two male worms. Nodules containing males alone were not found. Small nodules (less than 0.2 g) contained immature female worms without microfilariae and no males. As nodule size and female worm size increased, the number of female worms with microfilariae and the number of nodules with males increased reaching almost 100% in nodules weighing greater than 3.0 g. It is suggested that female worms normally become encapsulated when young, grow within the nodule and tht the male enters the nodule later, fertilises the female and remains in the nodule.
吉氏奥斯特线虫是从澳大利亚汤斯维尔94头自然感染牛身上采集的370个虫结节中的185个中提取的。185个结节中有183个含有一条雌虫，其中60%含有一条雄虫，7%含有两条雄虫。未发现仅含雄虫的结节。小的结节（小于0.2克）含有未成熟的无微丝蚴的雌虫，且无雄虫。随着结节大小和雌虫大小的增加，有微丝蚴的雌虫数量和有雄虫的结节数量增加，在重量大于3.0克的结节中几乎达到100%。有人认为，雌虫通常在年轻时被包囊，在结节内生长，而雄虫稍后进入结节，使雌虫受精并留在结节内。
