雌性大鼠唾液腺的组织学研究。holocyclus [来自袋狸]显示，存在的4种细胞类型中的2种在未进食阶段颗粒最丰富，但在24小时的附着期后排出这些颗粒。从未进食的女性和它的情况下，24小时的附件后唾液腺匀浆中的毒素的存在可能与这2种细胞类型的颗粒的损失后不久，附件。另一种细胞类型在整个饲养过程中颗粒含量逐渐增加，第4种细胞在120 h的附着期后颗粒含量达到峰值。后一种细胞类型可能产生麻痹毒素，因为蜱只有在大约这段时间进食后才会使宿主麻痹，而匀浆腺在120-144 h毒性最强。
Histological study of the salivary gland of female I. holocyclus [from bandicoots] showed that 2 of 4 cell types present are richest in granules in the unfed stage but have discharged these granules after an attachment period of 24 h. The presence of a toxin in homogenates of salivary glands from unfed females and its absence after 24 h of attachment may be associated with the loss of granules from these 2 cell types shortly after attachment. Another cell type shows a gradual increase in granule content throughout feeding and a 4th showed a peak in granule content after an attachment period of 120 h. The latter cell type may produce the paralyzing toxin since ticks do not paralyze the host until they have fed for about this time and homogenized glands are most toxic at 120-144 h.
