Bats are reservoirs for many different viruses, including some that can be transmitted to and cause disease in humans and/or animals. However, less is known about the bat-borne viruses circulating in Northern European countries such as in Sweden. In this study, saliva from bats, collected from south-central Sweden, was analyzed for viruses.

Increasing amounts of data indicate that bats harbor a higher viral diversity relative to other mammalian orders, and they have been recognized as potential reservoirs for pathogenic viruses, such as the Hendra, Nipah, Marburg, and SARS-CoV viruses. Here, we present the first viral metagenomic analysis of from Uppsala, Sweden. Total RNA was extracted from the saliva and feces of individual bats and analyzed using Illumina sequencing.

Article Synopsis
  • The COVID-19 pandemic has prompted research into animal reservoirs for coronaviruses, with bats being identified as a significant potential source.
  • In summer 2020, researchers in southern Sweden sampled 77 adult bats and successfully detected a novel coronavirus in the feces of a single female bat.
  • This finding marks the first instance of coronaviruses identified in Swedish bats, suggesting that they could contribute to the transmission cycle of coronaviruses in the region, highlighting the need for careful monitoring while considering conservation efforts for threatened bat species.

We present data on species composition and activity of bats during two years at three different wind- turbines, located in south Sweden, both at the base and nacelle height. To test the hypothesis that bats are attracted to wind turbines because of feeding opportunities, insects were sampled at nacelle height at one wind turbine using a suction trap, simultaneously as bat activity were measured. At this wind turbine, we also compared two different technical systems for ultrasound recordings and collect meteorological data.

To characterise mercury (Hg) exposure in Daubenton's bat (Myotis daubentonii, Kuhl 1817) in southern Sweden, 17 specimens were captured in 2013 and back fur samples were taken for analysis to determine Hg concentrations. The fur Hg levels determined [1.15 ± 0.
