If you have heard the term MSSA in your MRSA research and didn’t know what it meant, I ran into a little article today that explains it very simply.
MSSA stands for Methicillin-Sensitive Staphylococcus aureus and refers to all of the antibiotic-sensitive strains of Staph aureus, a common bacteria that can cause a wide variety of infections both in hospital and community environments. In other words, MSSA is the common type of Staph aureus that causes most Staph aureus infections and can be treated with penicillin-type antibiotics. [Source]
A Staph infection is either one or the other – resistant to or sensitive to (I also hear it frequently referred to as ‘susceptable’ to) antibiotics. I hope you all, like Cheryl who commented on this post, have only experience with MSSA. That is scary enough on its own.
