After testing against different bacteria, he found that the mould could kill only specific, Gram-positive bacteria. [11] For example, staphylococcus , streptococcus , and diphtheria bacillus ( Corynebacterium diphtheriae ) were easily killed; but there was no effect on typhoid bacterium ( Salmonella typhimurium ) and a bacterium once thought to ...
