本文比较了反复感染与蜱唾液腺或中肠提取物免疫对血红扇头蜱雌虫摄食和繁殖性能的影响。在每个免疫组中，三个蜱-幼稚的狗免疫三次蜱唾液腺或中肠提取物，并在21天的时间间隔两次挑战，让80名女性和40名男性成年蜱，以每一个主机。重复侵染组的三个幼稚的狗被侵染5次，在21天的时间间隔由相同数量的蜱。重复侵染组在第三次侵染后表现出蜱虫性能降低的趋势，但在第五次侵染前，一些蜱虫性能参数已恢复。蜱附着减少免疫与蜱唾液腺或中肠提取物。蜱唾液腺提取物免疫对雌蜱的取食期和饱食体重影响最大。免疫蜱中肠提取物导致蜱生殖力参数，其中包括产卵前，产卵，卵孵化期，除了减少产蛋量和鸡蛋的活力最大的减少。这些结果证实了狗可以对R产生耐药性。结果表明，蜱唾液腺和中肠提取物免疫对蜱的摄食和繁殖力有不同的影响。
Abstract This investigation compared the effects of repeated infestations to immunization of dogs with tick salivary gland or midgut extracts on the feeding and fecundity performances of femaleRhipicephalus sanguineus(Latrielle). In each immunized group, three tick-naive dogs were immunized three times with tick salivary gland or midgut extracts, and twice challenged at 21-d intervals by allowing 80 female and 40 male adult ticks to feed on each host. The repeated infestation group of three naive dogs was infested five times at 21-d intervals by the same numbers of ticks. The repeated infestation group showed a trend of reduced tick performance after the third infestation, but some of the tick performance parameters had recovered by the fifth infestation. Tick attachment was reduced by immunization with either tick salivary gland or midgut extract. Immunization with tick salivary gland extract had the greatest impact on the feeding period and engorgement weight of the female ticks. Immunization with tick midgut extract resulted in the greatest reduction of tick fecundity parameters, which included preoviposition, oviposition, and egg-incubation periods in addition to reduced egg production and egg viability. These results confirm that dogs can become resistant toR. sanguineus,and demonstrate that immunization with tick salivary gland or midgut extract has different effects on tick feeding and fecundity.
