 According to a study done by Oliver A. Todd and Brain M Peters, a newly discovered interaction between the pathogen Staphylococcus aureus and "fungal opportunist" Candida albicans is being considered a co-infection that is found in the bodies of sick patients who suffer from different conditions [2019].This kind of synergism was found to be lethal in a separate study conducted by Carlson on mice.When mice were infected with the two mentioned pathogens above independently, sickness resulted but the mice were able to recover.
