摘要

利用2017-20年间收集的意大利北部伦巴第大区野生动物布鲁氏菌监测数据,描述了野猪(Sus scrofa)、欧洲棕兔(Lepus europaeus)、秋鹿(Dama dama)、马鹿(Cervus elaphus)和狍子(Capreolus capreolus)等野生动物暴露于布鲁氏菌的情况。在检测的物种中,野猪(n=6,440)血清阳性样本的比例最高(5.9%)。值得注意的是,波河上游地区的野猪血清阳性率高于前阿尔卑斯地区的野猪。此外,在 2018 年的狩猎季节,采集了波河周缘地区野猪的 95 个器官(子宫或睾丸、脾脏和颌下淋巴结)进行细菌学检查。经培养,18.9% 的淋巴结分离出了猪布鲁氏菌。这些血清学和微生物学结果表明,野猪体内存在猪布氏杆菌,并表明野猪作为猪布氏杆菌储库的重要性。将布鲁氏菌血清阳性野猪的空间分布与散养猪场的位置进行比较后发现,只有在血清阳性样本比例较低的地区,两个种群之间的接触几率才较高。相反,在波河地区观察到的高比例血清阳性样本和阳性微生物培养结果表明,直接或间接参与野猪狩猎活动的人类面临更大的感染风险。这些结果可作为建立健全的野生动物管理和开展教育活动的依据,旨在降低参与野猪狩猎相关活动的人感染野猪的风险。

Brucella spp. in Wildlife of the Lombardy Region, Northern Italy.

Surveillance data collected in the period 2017-20 for Brucella spp. in wildlife of the Lombardy Region in northern Italy were used to describe the exposure of the wildlife species to Brucella spp. in wild boar (Sus scrofa), European brown hare (Lepus europaeus), fallow deer (Dama dama), red deer (Cervus elaphus), and roe deer (Capreolus capreolus). Among the tested species, wild boar (n=6,440) showed the highest percentage of seropositive samples (5.9%). Notably, wild boars of perifluvial area of the Po River showed higher percentages of positivity than those of the pre-Alpine district. In addition, during the hunting season in 2018, 95 organs (uterus or testes, spleen, and submandibular lymph nodes) from wild boar of the perifluvial area of the Po River were collected for bacteriological examination. Brucella suis was isolated in culture from 18.9% of tested lymph nodes. These serological and microbiological results highlight the presence of B. suis in wild boar and suggest the importance of wild boar as a reservoir for B. suis. Comparison of the spatial distribution of Brucella-seropositive wild boars with the location of backyard swine farms revealed a higher chance of contact between the two populations only in the areas where the lower percentage of seropositive samples was observed. Conversely, the high percentage of seropositive samples observed in the Po River area coupled with positive microbiological cultures suggest a greater risk of infection for the humans directly or indirectly involved in wild boar hunting activity. These results may serve as a basis to establish sound wildlife management and to adopt education campaigns aimed at reducing the risk of human infection in people involved in wild boar hunting related activities.

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.
