Abstract

This study reports on the first documented case of Amblyomma rotundatum ticks, a species typically found in the Americas, parasitising an imported toad in Poland. A total of 12 ticks were collected from a single Rhinella marina toad. These ticks were identified as female specimens of A. rotundatum using an examination of morphological characteristics and a molecular analysis. Polymerase chain reaction testing revealed that 75.0% (9/12) of these females were positive for Rickettsia spp. Sequencing of positive samples confirmed the presence of R. bellii. However, no DNA evidence of Borrelia spp. and Anaplasma spp. was detected in the tested ticks. Nevertheless, given the limited number of tick specimens collected from a single host, further research is required to elucidate the pathogen profile of a tick species. This finding represents the second European report of A. rotundatum associated with exported animals, underscoring the importance of vigilance in monitoring the potential spread of ticks and tick-borne pathogens through the global wildlife trade.

从莱茵拉码头进口到波兰的圆形圆眼肿中的贝立克次体的第一个欧洲记录。

本研究报告了首个记录在案的圆形无足蜱，一种在美洲通常发现的物种，寄生在波兰的一只进口蟾蜍上。从一只莱茵湾蟾蜍身上共采集到12只蜱虫。通过形态特征和分子分析鉴定，这些蜱属为圆尾蜱的雌性标本。聚合酶链反应检测显示，75.0%（9/12）的雌蚊立克次体呈阳性，阳性样本测序结果证实了贝氏弧菌的存在。但未检出伯氏疏螺旋体和无原体的DNA证据。然而，鉴于从单一宿主收集的蜱虫标本数量有限，需要进一步研究以阐明蜱虫物种的病原体特征。这一发现是欧洲报告的第二份与出口动物有关的轮状突蜱的报告，强调了在监测蜱和蜱传病原体通过全球野生动物贸易的潜在传播方面保持警惕的重要性。

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.
