A total of 207 wild rodents were caught on nine pig farms, five chicken farms and five non-farm locations in Sweden and surveyed for a selection of bacteria, parasites and viruses. Lawsonia intracellularia and pathogenic Yersinia enterocolitica were only detected in rodents on pig farms (9% and 8% prevalence, respectively) which indicate that these agents are more likely to be transmitted to rodents from pigs or the environment on infected farms. Brachyspira hyodysenteriae (1%), Brachyspira intermedia (2%), Campylobacter jejuni (4%), Campylobacter upsaliensis (2%), leptospires (7%) and encephalomyocarditis virus (9%) were also detected from rodents not in contact with farm animals. Giardia and Cryptosporidium spp. were common, although no zoonotic types were verified, and Salmonella enterica was isolated from 1/11 mice on one farm but not detected by PCR from any of the rodents. Trichinella spp. and Toxoplasma gondii were not detected.
总共在瑞典的 9 个猪场、5 个鸡场和 5 个非农场地点捕获了 207 只野生啮齿动物，并对它们进行了一系列细菌、寄生虫和病毒的检测。在猪场的啮齿动物中仅检测到了内氏放线菌和致病性小肠结肠炎耶尔森菌（分别为 9%和 8%的流行率），这表明这些病原体更有可能从感染猪场的猪或环境传播给啮齿动物。在与农场动物没有接触的啮齿动物中也检测到了短螺旋体（1%）、中间型短螺旋体（2%）、空肠弯曲菌（4%）、乌普萨拉弯曲菌（2%）、钩端螺旋体（7%）和脑心肌炎病毒（9%）。虽然没有发现人畜共患类型，但贾第虫和隐孢子虫很常见，沙门氏菌仅从一个猪场的 1/11 只老鼠中分离出来，但从任何啮齿动物中都未通过 PCR 检测到。旋毛虫和刚地弓形虫未被检出。
