Fungus and bacteria (IMAGE) University of Cambridge Caption Photo shows fungus Trichophyton erinacei growing in the centre of an agar plate streaked with MRSA on the left half and methicillin-susceptible Staphylococcus aureus bacteria on the right. The fungus produces antibiotics, which kill methicillin-susceptible Staphylococcus aureus bacteria but not MRSA, resulting in a clear zone on the right with no bacterial growth. Credit Claire L.
