摘要

本研究的目的是评估伊朗小型哺乳动物中人畜共患细菌的流行情况,包括伯氏柯谢氏菌、巴尔通体、立克次体、布鲁氏菌、伯氏疏螺旋体和埃利希氏体。我们研究了2016年至2020年间从伊朗不同地区收集的618种小型哺乳动物。我们从脾脏样本中提取DNA,并使用实时荧光定量PCR技术鉴定特异性基因。我们发现559份(90.45%)样本感染了至少一种分析病原体。巴尔通体阳性率为86.08%,埃利希氏体阳性率为2.42%,伯氏疏螺旋体阳性率为0.80%,伯氏疏螺旋体阳性率为0.64%,布鲁氏疏螺旋体阳性率为0.48%,立克次体阳性率为0%,其中以克拉氏巴尔通体(25.81%)和泰氏巴尔通体(25.81%)居多。本研究鉴定了一种感染流产布鲁氏菌的啮齿动物。在伯氏疏螺旋体阳性样本中,5个样本中有4个被鉴定为杜托尼伯氏疏螺旋体。在埃立克体属的阳性病例中,检出犬埃立克体、岛曼候选埃立克体和米库伦新埃立克体。以捕鼠最多的是桃梗鼠,共捕获315只(51.22%);我们的研究表明,分析的大部分小型哺乳动物感染了一种或多种目标病原体。在伊朗,鼠疫鼠对伯氏体、巴尔通体、埃利希体、布鲁氏体和伯氏体的感染率显著高于其他啮齿动物,这表明该啮齿动物可能是人畜共患病原体的重要宿主。

Assessing the diversity of zoonotic bacterial agents in rodents and small mammals in Iran.

The purpose of this study was to assess the prevalence of zoonotic bacteria, including Coxiella burnetii, Bartonella spp., Rickettsia spp., Brucella spp., Borrelia spp., and Ehrlichia spp., among small mammalian in Iran. We examined 618 small mammals collected between 2016 and 2020 from different parts of Iran. We extracted DNA from spleen samples and used quantitative real-time PCR to identify specific genes. We found 559 (90.45%) samples infected with at least one of the analyzed pathogens. Among the studied specimens, 86.08% tested positive for Bartonella spp., 2.42% for Ehrlichia spp., 0.80% for Borrelia spp., 0.64% for C. burnetii, 0.48% for Brucella spp., and 0% for Rickettsia spp. Bartonella krasnovii (25.81%) and Bartonella taylorii (25.81%) were the most prevalent among the Bartonella species. This study identified a rodent infected with Brucella abortus. Among the Borrelia-positive samples, four out of five were identified as Borrelia duttonii. Among the positive cases in the Ehrlichia genus, Ehrlichia canis, Candidatus Ehrlichia shimanensis, and Neoehrlichia mikurensis were identified. Meriones persicus was the most prevalent captured rodent with 315 specimens (51.22%). Our study revealed that a large proportion of the small mammals analyzed were infected with one or more of the targeted pathogens. M. persicus exhibited significant infection rates with C. burnetii, Bartonella spp., Ehrlichia spp., Brucella spp., and Borrelia spp. This suggests that this rodent species could serve as a crucial reservoir for zoonotic pathogens in Iran.
