(order Eulipotyphla, families Soricidae and Talpidae) in central and southeastern Poland. In this exploratory study, we attempted to Methods: RNAlater®-preserved patagia and feces from 88 vesper bats, collected during 2013, 2014 and 2017 in northern, central . Results and Discussion: Despite repeated and exhaustive attempts, using oligonucleotide primers and PCR cycling conditions that and south-central Poland, were analyzed for hantavirus RNA by nested reverse transcription polymerase chain reaction (RT-PCR) including the common noctule (Nyctalus noctula led to the discovery of bat-borne hantaviruses in Asia and Africa, we failed to detect hantavirus RNA in vesper bats from Poland, ), which has recently been shown to harbor a hantavirus in the Czech Republic.

Live-caught bats were released af In addition to shrews and moles, bats (order Chiroptera) are now served in RNAlater®.

Thus, apart from the small sample size, patagia and RNAlater®-preserved patagia and feces from 88 vesper bats feces may not be suitable to truly assess hantavirus infection in - bats. Moreover, hantavirus infection is typically focal and not uni- ously described protocols [3-6, 13-15] were analyzed for hantavirus RNA by nested RT-PCR, using previ - it could be that the common noctule population in the particular . Total RNA was extracted, formly distributed within a given host species in time and space.
