Thanks for the correction, Eggcessive. I learn so much from you and the other Educators. I have corrected my post.Neosporin ointment does treat staphylococcus and other bacteria. It consists of 3 antibiotics—neomycin, bacitracin, and poly mix in B. That is why it is used for skin wounds, and in eye ointments. Neomycin treats both gram positive and gram negative bacteria, and poly mix in B is effective against gram negative. Bacitracin is antiinfective.
