is a vector-borne zoonotic bacterium that causes tularemia, a disease of great importance for animal and public health. Although wild lagomorphs are considered one of the major reservoirs of this bacterium, information about the circulation of in European wild rabbit () and Iberian hare () populations in Europe is still very limited. In Spain, is present in northern central regions, with recurrent outbreaks occurring annually. However, southern Spain has been neglected in terms of monitoring and research. Thus, the aim of this study was to investigate the occurrence of in wild lagomorphs in the Mediterranean ecosystems of southern Spain through using molecular techniques. Spleen samples from 774 European wild rabbits and 178 Iberian hares were collected on 135 hunting grounds between the 2017/2018 and 2022/2023 hunting seasons. A primer set targeting the 16S rRNA gene was used for the detection of DNA. None of the 952 (0.0%; 95%CI: 0.0-0.4) wild lagomorphs sampled showed presence of DNA. Our finding indicates the absence or very low circulation of the bacterium in wild rabbit and Iberian hare populations in the Mediterranean ecosystems of southern Spain, denoting a limited risk of transmission of this pathogen from wild lagomorphs to other sympatric species, including human beings, in this Iberian region.
是一种通过媒介传播的人畜共患细菌,可引发兔热病,这是一种对动物和公共卫生至关重要的疾病。尽管野生兔形目动物被认为是这种细菌的主要宿主之一,但关于该细菌在欧洲野兔(Oryctolagus cuniculus)和伊比利亚野兔(Lepus granatensis)种群中的传播情况,欧洲的相关信息仍然非常有限。在西班牙,该细菌存在于中北部地区,每年都会反复爆发。然而,西班牙南部在监测和研究方面一直被忽视。因此,本研究的目的是通过分子技术调查西班牙南部地中海生态系统中野生兔形目动物体内该细菌的存在情况。在2017/2018年至2022/2023年狩猎季节期间,从135个狩猎场收集了774只欧洲野兔和178只伊比利亚野兔的脾脏样本。使用一组靶向16S rRNA基因的引物来检测弗朗西斯菌属DNA。在采集的952只(0.0%;95%置信区间:0.0 - 0.4)野生兔形目动物样本中,均未检测到弗朗西斯菌属DNA。我们的研究结果表明,在西班牙南部地中海生态系统的野兔和伊比利亚野兔种群中,该细菌不存在或传播率极低,这表明在伊比利亚地区,这种病原体从野生兔形目动物传播到其他同域物种(包括人类)的风险有限。
