This paper represents the first description of advanced aelurostrongylosis in the Eurasian badger (Меles meles, L. 1758) from Bosnia and Herzegovina, which is an autochthonous species of the country. An adult female badger was found dead on a road; the cause of death was trauma but the emphasis in the paper is on severe verminous pneumonia caused by metastrongylids from genus Aelurostrongylus spp. This parasitological and histopathological finding confirms the presence of Aelurostrongylus in mustelids in Bosnia and Herzegovina and the Balkans.
