Abstract

Ixodes scapularis and Ixodes pacificus are vectors of a range of pathogens of public health significance in North America. These ticks transmit pathogens to and from wild animal reservoir host species, but also bite humans and expose them to the pathogens. We describe the geographical and temporal distribution of the pathogen Babesia odocoilei, the causative agent of cervid babesiosis. Ixodes spp. ticks collected through active and passive surveillance were submitted to the National Microbiology Laboratory of the Public Health Agency of Canada for analysis of the presence of B. odocoilei from 2018 to 2021. Generalized linear models were constructed to evaluate the temporal change of B. odocoilei prevalence across Canada. Babesia odocoilei-positive I. scapularis are widespread across south-central and eastern regions of Canada, with an overall prevalence of 12.0 % in both nymphs (CI 95 % : 11.4-12.6) and adults (CI 95 % : 11.9-12.1) collected in passive surveillance and 13.2 % (CI 95 % : 12.9-13.5) and 10.0 % (CI 95 % : 9.8-10.2) in nymphs and adult, respectively, collected in active surveillance. A single I. pacificus tick tested positive in active surveillance out of 29 ticks collected in British Columbia, while no B odocoilei-positive I. scapularis were found in passive surveillance among the 11 adult ticks tested. Although B. odocoilei infection prevalence of adult I. scapularis was significantly higher in 2019 (14.1 %) than in 2018 (7.4 %), it remained stable from 2019 to 2021, suggesting that this pathogen may already be well established in endemic tick populations. The results provided in this article represent, to date, the most comprehensive picture of B. odocoilei distribution and prevalence in ticks in Canada and highlight the interest of maintaining One Health surveillance approaches to give added insight into disease transmission cycles for less well-characterized microorganisms.

加拿大 Ixodes 种蜱虫中巴贝斯菌的分布:对健康监测的影响。
Ixodes scapularis 和 Ixodes pacificus 是北美洲一系列具有公共卫生意义的病原体的传播媒介。这些蜱虫在野生动物蓄积宿主物种之间传播病原体,同时也叮咬人类,使人类接触到病原体。我们描述了病原体巴贝西亚原虫(Babesia odocoilei)的地理分布和时间分布,巴贝西亚原虫是颈鹿巴贝西亚病的病原体。从 2018 年到 2021 年,通过主动和被动监测收集的 Ixodes spp.我们构建了广义线性模型,以评估加拿大全境 B. odocoilei 流行率的时间变化。在加拿大中南部和东部地区,恙螨巴贝西亚原虫阳性蜱(I. scapularis)广泛存在,被动监测收集的若虫(CI 95 %:11.4-12.6)和成虫(CI 95 %:11.9-12.1)的总体流行率为 12.0%,主动监测收集的若虫和成虫的流行率分别为 13.2%(CI 95 %:12.9-13.5)和 10.0%(CI 95 %:9.8-10.2)。在不列颠哥伦比亚省采集的 29 只蜱虫中,只有一只 I. pacificus 蜱虫在主动监测中检测出阳性,而在被动监测中检测的 11 只成年蜱虫中,没有发现 B. odocoilei 阳性的 I. scapularis。虽然2019年(14.1%)成年鳞栉蜱的B. odocoilei感染率明显高于2018年(7.4%),但从2019年到2021年保持稳定,这表明这种病原体可能已经在地方性蜱群中很好地建立起来。本文提供的结果是迄今为止最全面的加拿大蜱虫B. odocoilei分布和流行情况,并强调了保持 "同一健康 "监测方法的重要性,以进一步了解特征不太明显的微生物的疾病传播周期。

期刊介绍: Ticks and Tick-borne Diseases is an international, peer-reviewed scientific journal. It publishes original research papers, short communications, state-of-the-art mini-reviews, letters to the editor, clinical-case studies, announcements of pertinent international meetings, and editorials. The journal covers a broad spectrum and brings together various disciplines, for example, zoology, microbiology, molecular biology, genetics, mathematical modelling, veterinary and human medicine. Multidisciplinary approaches and the use of conventional and novel methods/methodologies (in the field and in the laboratory) are crucial for deeper understanding of the natural processes and human behaviour/activities that result in human or animal diseases and in economic effects of ticks and tick-borne pathogens. Such understanding is essential for management of tick populations and tick-borne diseases in an effective and environmentally acceptable manner.
