Four consecutive annual calf crops of known genotype from a single property in northern Australia were examined for the presence of stephanofilarial lesions. The animals ranged in age from 60 to 348 days at the time of examination. Initial lesions of stephanofilariasis developed adjacent to the medial canthi of the eyes; animals as young as 69 days of age were found infected. In all years, prevalence of lesions increased with age for all genotypes, and was significantly lower in genotypes with higher Bos indicus content (P less than 0.01). Males had a higher prevalence of lesions than females in only one year, and in two of the years, dark-coloured animals had a higher prevalence of lesions than light-coloured ones.
对澳大利亚北部一个单一牧场连续四年已知基因型的犊牛进行检查，以确定是否存在丝状虫病病变。检查时，动物年龄在60至348天之间。丝状虫病的初始病变发生在眼睛内眦附近；发现年仅69天的动物被感染。在所有年份中，所有基因型的病变患病率均随年龄增长而增加，而印度瘤牛血统比例较高的基因型患病率显著较低（P<0.01）。仅在一年中，雄性动物的病变患病率高于雌性，在两年中，深色动物的病变患病率高于浅色动物。
