The role of environmental factors in presence of non-tuberculous mycobacteria in Myotis myotis summer shelter guano
Original language description
Non-tuberculous mycobacteria (NTM) are widespread and found in all biotopes, including caves. Some NTMs are potentially pathogenic, causing serious diseases (mycobacterioses) in both animals and humans. This study assesses the effect of various environmental factors on presence of NTM in guano samples of the greater mouse-eared bat (Myotis myotis) collected in 2020 and 2021 from 68 summer roosts throughout the Czech Republic. NTM presence was evaluated by direct microscopy after Ziehl–Neelsen staining, culture examination and real-time quantitative PCR (qPCR). Environmental factors that could potentially affect NTM presence were obtained through GIS and geochemical analysis. While qPCR confirmed high NTM prevalence in bat guano samples (80.9 %), prevalences by standard microscopy and cultivation were much lower (35.1 % and 25.7 %, respectively). In total, ten Mycobacteria were isolated: M. arupense, M. avium subsp. hominissuis, M. chitae, M. fortuitum, M. gordonae, M. kumamotonense, M. litorale, M. peregrinum, M. terrae and M. terrae complex. While presence of the heavy metals palladium and molybdenum had a significant impact on NTM presence, suggesting heavier NTM infestation at polluted sites, landscape, climate and geochemical parameters did not explain differences in NTM load at different sites, possibly due to the high similarity of habitats chosen by M. myotis throughout the Czech Republic.
