Hibernating vesper bats are a weak source for biomonitoring of coronaviruses
Résumé
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.
