摘要

钩端螺旋体病是一种复杂且经常被低估的全球性细菌性疾病,仍然是人畜共患疾病。该病诊断困难,发病机制不明确。近年来发现了钩端螺旋体属的几个新种;这些物种对动物健康的影响尚不清楚。2013年,在爱尔兰的大白齿鼩(GWTSs, Crocidura russula)中首次发现了钩端螺旋体,它们是取代当地侏儒鼩(Sorex minutus)的入侵物种。本研究利用组织病理学(n=212)、免疫组化(IHC;n=206)和肾组织定量PCR (n=168)。采用组织病理学(n=81)和免疫组化(n=79)对来自法国Belle Île的81只鼩鼱作为物种和栖息地对照组进行检查。用任何方法在爱尔兰取样的鼩鼱肾组织中均未检测到钩端螺旋体,并且没有明显的肾脏病理。相比之下,来自Belle Île的34.6%(28/81)鼩鼱钩端螺旋体免疫组化阳性,组织病理学上伴有慢性肾炎。结果表明,L. tipperaryensis或其他钩端螺旋体对爱尔兰GWTS和侏儒鼩的健康和分布没有负面影响;目前看来不太可能在鼩鼱种群中继续传播。

Surveillance for Leptospira sp. in Native and Invasive Shrews in Ireland Compared with Cohabitating Shrews in France.

Leptospirosis is a complex and often underestimated global bacterial disease that continues to be of zoonotic concern. It is difficult to diagnose and has an unclear pathogenesis. Several new species of the genus Leptospira have been discovered in recent years; the impact of these species on animal health is unknown. In 2013, Leptospira tipperaryensis was first identified in greater white-toothed shrews (GWTSs, Crocidura russula) in Ireland, where they are an invasive species that displaces the native pygmy shrew (Sorex minutus). This study investigated the prevalence of Leptospira spp., including L. tipperaryensis, and their potential impact on the health of shrews from Ireland using histopathology (n=212), immunohistochemistry (IHC; n=206), and quantitative PCR (n=168) on renal tissues. Shrews (n=81) from Belle Île, France were examined as a species and habitat control group using histopathology (n=81) and IHC (n=79). No Leptospira were detected with any of the methods in renal tissues from shrews sampled in Ireland and there was no significant renal pathology. In contrast, 34.6% (28/81) of shrews from Belle Île were positive on IHC for Leptospira sp. and had associated chronic nephritis in histopathology. The results do not indicate a negative impact by L. tipperaryensis or other Leptospira spp. on the health and distribution of the GWTS and the pygmy shrew in Ireland; onward transmission within the shrew population currently appears unlikely.

期刊介绍: The JWD publishes reports of wildlife disease investigations, research papers, brief research notes, case and epizootic reports, review articles, and book reviews. The JWD publishes the results of original research and observations dealing with all aspects of infectious, parasitic, toxic, nutritional, physiologic, developmental and neoplastic diseases, environmental contamination, and other factors impinging on the health and survival of free-living or occasionally captive populations of wild animals, including fish, amphibians, reptiles, birds, and mammals. Papers on zoonoses involving wildlife and on chemical immobilization of wild animals are also published. Manuscripts dealing with surveys and case reports may be published in the Journal provided that they contain significant new information or have significance for better understanding health and disease in wild populations. Authors are encouraged to address the wildlife management implications of their studies, where appropriate.
