This study aimed to determine the incidence of canine and feline tick paralysis cases presenting to two veterinary emergency hospitals before and after the introduction of new generation prophylactic acaricides.
This was a retrospective study, investigating the number of tick paralysis cases presenting to two emergency and critical care veterinary hospitals in South-East Queensland, from 2008 to 2021. A total of 10,914 dogs and 3696 cats were included over the course of the study. To assess if the introduction of new generation prophylactics in 2015 has coincided with any variation in case numbers, data for each species were analysed graphically and numerically in the first instance, then interrupted time series analyses were performed for the dog and cat data independently.
Accounting for seasonal and climatic variation, we estimated a 54.8% reduction in dog (95% CI 45.3%-62.7%) and 44% reduction in cat (95% CI 19.5%-46%) tick paralysis cases presenting to these two clinics. This reduction corresponded with the timing of new generation prophylactic agents being introduced, including isoxazolines and imidacloprid/flumethrin impregnated collars.
In the population studied, a significant reduction in the incidence of tick paralysis cases treated by veterinarians has occurred from 2015 onwards and was found to be associated with the timing of the release of new generation acaricidal products.
本研究旨在确定在引入新一代预防杀蜱剂前后，两家兽医急诊医院犬猫蜱瘫痪病例的发生率。
这是一项回顾性研究，调查了 2008 年至 2021 年期间昆士兰州东南部两家急诊和重症监护兽医医院出现的蜱瘫痪病例数量。在研究过程中，共纳入了 10914 只狗和 3696 只猫。为了评估新一代预防剂的引入是否与病例数量的变化有关，首先对每种动物的数据进行图形和数值分析，然后对狗和猫的数据分别进行中断时间序列分析。
考虑到季节性和气候变化，我们估计这些诊所的犬（95%置信区间 45.3%-62.7%）和猫（95%置信区间 19.5%-46%）蜱瘫痪病例数分别减少了 54.8%。这种减少与新一代预防剂的引入时间相对应，包括异恶唑啉类和吡虫啉/氟氯苯菊酯浸渍项圈。
在所研究的人群中，兽医治疗的蜱瘫痪病例的发病率从 2015 年以来显著下降，并且与新一代杀蜱产品的释放时间有关。
