Abstract

Background: European hedgehogs (Erinaceus europaeus) are widely distributed across Europe. They may play an important role by spreading zoonotic bacteria in the environment and to humans and animals. The aim of our work was to study the prevalence and characteristics of the most important foodborne bacterial pathogens in wild hedgehogs.

Results: Faecal samples from 148 hospitalised wild hedgehogs originating from the Helsinki region in southern Finland were studied. Foodborne pathogens were detected in 60% of the hedgehogs by PCR. Listeria (26%) and STEC (26%) were the most common foodborne pathogens. Salmonella, Yersinia, and Campylobacter were detected in 18%, 16%, and 7% of hedgehogs, respectively. Salmonella and Yersinia were highly susceptible to the tested antimicrobials. Salmonella Enteritidis and Listeria monocytogenes 2a were the most common types found in hedgehogs. All S. Enteritidis belonged to one sequence type (ST11), forming four clusters of closely related isolates. L. monocytogenes was genetically more diverse than Salmonella, belonging to 11 STs. C. jejuni ST45 and ST677, Y. pseudotuberculosis O:1 of ST9 and ST42, and Y. enterocolitica O:9 of ST139 were also found.

Conclusions: Our study shows that wild European hedgehogs should be considered an important source of foodborne pathogens, and appropriate hygiene measures after any contact with hedgehogs and strict biosecurity around farms are therefore important.

欧洲野生刺猬(Erinaceus europaeus)中的食源性致病菌。
背景:欧洲刺猬(Erinaceus europaeus)广泛分布于欧洲各地。它们可能会在环境中向人类和动物传播人畜共患病细菌,从而发挥重要作用。我们的工作旨在研究最重要的食源性细菌病原体在野生刺猬中的流行情况和特征:研究了来自芬兰南部赫尔辛基地区的 148 只住院野生刺猬的粪便样本。通过 PCR 检测,60% 的刺猬体内检出了食源性病原体。李斯特菌(26%)和 STEC(26%)是最常见的食源性病原体。在 18%、16% 和 7% 的刺猬中分别检测到沙门氏菌、耶尔森氏菌和弯曲杆菌。沙门氏菌和耶尔森氏菌对测试的抗菌药高度敏感。肠炎沙门氏菌和单核细胞增生李斯特菌 2a 是刺猬中最常见的菌种。所有肠炎沙门氏菌都属于一种序列类型(ST11),形成了四个密切相关的分离物群。单核细胞增多性嗜酸乳杆菌的基因比沙门氏菌更多样化,属于 11 个 ST。此外,还发现了空肠肠杆菌 ST45 和 ST677、假结核杆菌 ST9 和 ST42 的 O:1 以及小肠结肠炎病毒 ST139 的 O:9:我们的研究表明,欧洲野生刺猬应被视为食源性病原体的重要来源,因此在与刺猬接触后采取适当的卫生措施以及在养殖场周围实施严格的生物安全措施非常重要。
