Taxonomic overview of the genus Arthroderma with focus on species associated with reptiles and bats
Kolarczyková, Daniela ; Hubka, Vít (advisor) ; Dobiáš, Radim (referee)
The genus Arthroderma belongs to a group of geophilic dermatophytes that primarily degrade keratin in soil and occasionally cause infections in humans and animals. This species-rich genus has received particular attention in recent years in terms of species occurring in human clinical material or clinical samples isolated from rodents and other mammals, which has been associated with a significant increase in the number of its species. In this thesis, the species diversity of the genus Arthroderma was investigated in material isolated from snakes, bats and cave sediment, a substrate that has been almost unexplored in terms of the occurrence of this genus. The strains studied were isolated during research on bats diseased by "white nose syndrome" and snakes by "snake fungal disease". In the past, the genus Arthroderma has been studied either on the basis of morphology or, after the advent of molecular methods, in terms of multigene phylogeny. However, no monographs have simultaneously combined phenotypic and molecular genetic criteria to assess species boundaries across the genus or a significant part of it. This is one of the reasons why species boundaries are often unclearly defined. Thus, another aim of this work was to improve the multigene phylogeny of the genus by incorporating new strains,...
