Abstract

The Sierra Nevada de Santa Marta (SNSM), located in northern Colombia, is considered a geographical island with high levels of biodiversity and endemism. However, little is known about tick species and their associated microorganisms at the SNSM. In this study we sampled host-seeking ticks in areas of the town of Minca within the SNSM. We collected 47 ticks identified as Amblyomma pacae, Amblyomma longirostre, Amblyomma ovale, Amblyomma mixtum, Haemaphysalis juxtakochi, Ixodes sp. cf. Ixodes affinis and Ixodes sp. Of these ticks, we tested for Rickettsia spp. by amplifying the gltA, SCA1, and 16S rRNA genes via PCR. Rickettsia amblyommatis was detected in one pool of 3 larvae and in a female of A. pacae. Additonally, we isolated Rickettsia sp. belonging to the group of spotted fevers in larvae of A. longirostre. This study reports new findings of six species of ticks and two species of Rickettsia within the SNSM.

哥伦比亚圣玛尔塔内华达山脉新发现的硬蜱（Acari: Ixodidae）以及蜱中立克次体的检测结果

圣玛尔塔内华达山脉（SNSM）位于哥伦比亚北部，被认为是一个具有高度生物多样性和特有性的地理岛屿。然而，人们对圣玛尔塔内华达山脉的蜱虫物种及其相关微生物知之甚少。在这项研究中，我们在 SNSM 内的明卡镇地区采集了寻找宿主的蜱虫样本。在这些蜱虫中，我们通过 PCR 扩增 gltA、SCA1 和 16S rRNA 基因，检测了立克次体。在一组 3 只幼虫和一只雌性 A. pacae 中检测到了安氏立克次体（Rickettsia amblyommatis）。此外，我们还在 A. longirostre 的幼虫体内分离到了属于斑疹热病的立克次体。本研究报告了 SNSM 中 6 种蜱虫和 2 种立克次体的新发现。

期刊介绍： Experimental and Applied Acarology publishes peer-reviewed original papers describing advances in basic and applied research on mites and ticks. Coverage encompasses all Acari, including those of environmental, agricultural, medical and veterinary importance, and all the ways in which they interact with other organisms (plants, arthropods and other animals). The subject matter draws upon a wide variety of disciplines, including evolutionary biology, ecology, epidemiology, physiology, biochemistry, toxicology, immunology, genetics, molecular biology and pest management sciences.
