Brown hare () populations in Europe have declined through decades due to several, but not clear yet, factors. Parasite infections and diseases are some of the causes that directly affected the survival and breeding rates of animal population. A study on the endoparasites of 70 hares (37 hunted free-living hares, and 33 bred on farms hares) was performed between 2015 - 2017 in the province of Grosseto (central Italy), an area where the impact of parasites in the hare population has never been investigated. During necroscopic analysis of hunted hares the following helminthes were found: (87.1 %), (12.9 %) and spp. (6.4 %) in the intestinal tract, (8.3 %) in lungs and (16.7 %) in livers. The prevalences of the intestinal helminthes in bred hares were: 12.1 % for and 3 % for . The coprological analysis showed prevalences of 64.9 % for coccidia in the 37 hunted hares and 45.5 % in the 33 bred hares. The relationship between the intensities of parasitic infections and body weight was evaluated. The results of the present study in the Grosseto area indicate that free-living hares have few species of parasites and that the intensities of parasitic infection did not affect their general condition and health, suggesting that endoparasites played no detectable role in the dynamics of this hare population.
由于多种尚不明确的因素，欧洲的棕兔（）数量在数十年间持续减少。寄生虫感染和疾病是直接影响动物种群生存和繁殖率的部分原因。2015年至2017年期间，在意大利中部格罗塞托省开展了一项针对70只野兔（37只野外捕获的野兔和33只农场养殖的野兔）体内寄生虫的研究，该地区野兔种群中寄生虫的影响此前从未被研究过。在对野外捕获野兔的尸检分析中，在肠道发现了以下蠕虫：（87.1%）、（12.9%）和 spp.（6.4%），在肺部发现（8.3%），在肝脏发现（16.7%）。养殖野兔肠道蠕虫的感染率分别为：12.1%和3%。粪便学分析显示，37只野外捕获野兔球虫感染率为64.9%，33只养殖野兔感染率为45.5%。评估了寄生虫感染强度与体重之间的关系。格罗塞托地区的本研究结果表明，野外生存的野兔体内寄生虫种类较少，寄生虫感染强度并未影响它们的总体状况和健康，这表明体内寄生虫在该野兔种群动态中未起到可检测到的作用。
