Brucellosis is a zoonosis caused by different species. Wild boar () could be infected by some species and represents an important reservoir, especially for biovar 2. This study aimed to investigate the prevalence of spp. by serological and molecular assays in wild boar hunted in Tuscany (Italy) during two hunting seasons. From 287 animals, sera, lymph nodes, livers, spleens, and reproductive system organs were collected. Within sera, 16 (5.74%) were positive to both rose bengal test (RBT) and complement fixation test (CFT), with titres ranging from 1:4 to 1:16 (corresponding to 20 and 80 ICFTU/mL, respectively). spp. DNA was detected in four lymph nodes (1.40%), five epididymides (1.74%), and one fetus pool (2.22%). All positive PCR samples belonged to biovar 2. The results of this investigation confirmed that wild boar represents a host for biovar. 2 and plays an important role in the epidemiology of brucellosis in central Italy. Additionally, epididymis localization confirms the possible venereal transmission.
布鲁氏菌病是一种由不同物种引起的人畜共患病。野猪( )可能会被某些物种感染,是一个重要的宿主,特别是对于生物变种2。本研究旨在通过血清学和分子检测方法调查在两个狩猎季节期间于意大利托斯卡纳捕获的野猪中 属物种的流行情况。从287只动物身上采集了血清、淋巴结、肝脏、脾脏和生殖系统器官。在血清中,16份(5.74%)对虎红试验(RBT)和补体结合试验(CFT)均呈阳性,滴度范围为1:4至1:16(分别对应20和80国际补体结合试验单位/毫升)。在4个淋巴结(1.40%)、5个附睾(1.74%)和1个胎儿样本(2.22%)中检测到了 属物种的DNA。所有PCR阳性样本均属于生物变种2。本调查结果证实野猪是生物变种2的宿主,并且在意大利中部布鲁氏菌病的流行病学中发挥着重要作用。此外,附睾部位的发现证实了可能存在性传播。
