Genetic hitchhikers make Aspergillus infections even harder to treat

Resistance to antifungal medicines in the pathogenic fungus Aspergillus fumigatus is proving more persistent than previously thought. Research by Wageningen University & Research (WUR), published in Current Biology, shows that fungicides used in agriculture, even those with a different mode of action from these medicines, can help maintain this resistance. This is because different resistance genes "hitchhike" together.
