Aspergillus is a group of mold species commonly found both indoors and outdoors. Most of us likely breathe in Aspergillus spores on a daily basis without them causing any harm or sickness [1]. Aspergillus can be a member of a healthy gut microbiome, but can cause an infection called aspergillosis in people with weakened immune systems [2], [3]. (Adapted from Tiny Health) We consider low or undetectable levels of Aspergillus optimum.
