Abstract

Background

Our study explores the role of bats as reservoirs of coronaviruses.

Methods

We conducted virological screening of bats hibernating in military bunkers at the Natura 2000 site “Nietoperek” in Western Poland collecting oral and anal swab samples from 138 bats across six species to apply a combination of pan-coronavirus and SARS-CoV-2 specific PCR assays.

Results

Only one anal swab tested positive for coronavirus. No SARS-CoV-2 was detected in any of the samples. The low prevalence of coronavirus in the studied colony contrasts with higher rates found in other regions and may be influenced by hibernation.

Conclusions

Hibernating bats may show a low prevalence of coronavirus, potentially due to the hibernation process itself. This finding indicates that hibernating bats may not be the most optimal subjects for screening zoonotic pathogens. However, biomonitoring of bats for emerging and reemerging diseases is recommended for comprehensive epidemiological insights.

冬眠的紫斑蝙蝠是冠状病毒生物监测的薄弱来源

方法我们对在波兰西部自然保护区 2000（Natura 2000）"Nietoperek "的军事掩体中冬眠的蝙蝠进行了病毒学筛查，收集了 138 只蝙蝠的口腔和肛门拭子样本，这些样本来自 6 个物种，采用了泛冠状病毒和 SARS-CoV-2 特异性 PCR 检测组合。结果只有一个肛拭子的冠状病毒检测呈阳性，所有样本中都没有检测到 SARS-CoV-2。结论冬眠蝙蝠的冠状病毒感染率较低，这可能与冬眠过程本身有关。这一发现表明，冬眠蝙蝠可能不是筛查人畜共患病病原体的最佳对象。不过，建议对蝙蝠进行新发和再发疾病的生物监测，以获得全面的流行病学见解。
