Thirty or more microfilariae 0.70-1.32 mm in length were recovered from the hemocele of an unengorged adult tick, Ixodes dammini, that was collected from vegetation on Shelter Island, New York. Among approximately 500 I. dammini collected from the same area only 1 other was similarly infected. Outstanding features, in addition to size, were absence of a cephalic space and the presence of nuclei in 2 or 3 irregular rows extending to the end of a bluntly rounded tail. The microfilariae apparently were ingested in a blood meal that was taken when the ticks were larvae or nymphs, and had persisted alive without development.
从一只未饱血的成年达敏硬蜱（Ixodes dammini）的血腔内发现了30条或更多长度为0.70 - 1.32毫米的微丝蚴。这只蜱采自纽约 Shelter 岛的植被上。在从同一地区采集的约500只达敏硬蜱中，只有另外1只受到了类似感染。除大小外，这些微丝蚴的显著特征是没有头部间隙，并且在2或3排不规则排列的细胞核延伸至钝圆尾部末端。这些微丝蚴显然是蜱在幼虫或若虫阶段吸食血餐时摄入的，并且一直存活但未发育。
