B chromosomes (Bs) are supernumerary to the standard chromosome set, from which they prevalently
derive. Variation in numbers both among individuals or populations and among cells within individuals
is their constant feature. Leisler’s bat Nyctalus leisleri (Kuhl, 1817) is one of only four species of Chiroptera
with detected Bs. Four males of N. leisleri were collected from two localities on the territory of Serbia
and cytogenetically analysed. All animals had Bs with interindividual variability ranging from two to
five heterochromatic micro Bs. The highest number of Bs was detected in this species. Among mammals,
Rodentia and Chiroptera are orders with the largest number of species, but Bs frequently appear in rodents
and rarely in chiropterans. Possible explanations for this difference are offered.
