摘要: 指状腹腔丝虫与马来丝虫的蜡肠期幼虫除尾部有无尾核可作区分依据外,前者头小,基部国钝呈圆锥状,小尾尖细如钉。感染前期幼虫的大小、食道长短和尾部形态也有区别。指状腹腔丝虫感染期幼虫尾端有3个刺状小乳突,排列如山字形,食道平均占体长3/4,肛比率小于3,而马来丝虫感染期幼虫尾端的3个乳突较大,呈瘤状,食道仅占体长的1/3,肛比率约为4。

Abstract: Sausage stage: The larva of B. malayi has two caudal nuclei, a small, nail-shaped tail and a small, conical head which distinguish it from that of S. digitate.Pre-infective stage: In contrast to S. digitata, B. malayi is small in size and has a shorter esophagus. Moreover, the posterior end of B. malayi is narrow and like a leaf of willow while that of S. digitata is blunt.Infective stage: B. malayi is characterized by three big tuberant papillae at the pos-terior end while the three papillae of S. digitata are small and rod-shaped. Anal ratio is greater in B. malayi (around 4) than in S. digitata (less than 3). Esophagus/total length ratio of the former is 1/3 while that of the latter 3/4.
