Serratia marcescens… What in the world is that? An Italian dish? An exotic island town? Neither. It’s the name of a bacteria that you’ve probably never heard of—a bacteria that had taken up residence in my tonsils.
Serratia can be found anywhere, but it thrives in hospitals and in damp spaces like bathrooms. If you see a pink or orangish ring around a drain (such as mine, pictured above), it might be Serratia. Most people never have trouble living near the organism, but in hospital settings, it can cause serious problems. For me, having it in my tonsils was likely an ongoing trigger making my immune system attack my brain.
