Epistasis limits but does not prevent the transfer of mutation-drug resistance mapping across 600 million years of fungal evolution

Whether different pathogens acquire resistance to antimicrobials through the same mutations is a major question in evolution and microbiology. Most antifungal drugs are used to treat infections caused...

Transcriptional and metabolic modeling analyses of developing Aspergillus fumigatus biofilms reveal metabolic shifts required for biofilm maturation | mSphere

Aspergillus fumigatus is the most common etiological agent of a collection of diseases termed aspergillosis. Chronic and invasive manifestations of aspergillosis are highlighted by the development of biofilm-like structures on and in tissue. These biofilm structures are resistant to contemporary antifungal drugs, even for strains that are susceptible by standard antimicrobial susceptibility testing methods. Consequently, understanding the mechanisms by which A. fumigatus induces, develops, and maintains biofilms to evade antifungal therapies is expected to illuminate biofilm-specific therapeutic targets. Here, we identify genes involved in fungal fermentation and regulation of transcription as important mediators of A. fumigatus biofilm development.
