I started this week culturing Serratia Marcescens, and I got some more pictures of M.L. I spent more time working on precalculus and chem 152 homework, but I did a little research on Serratia Marcescens. Here are some fun facts about S.M. -slimy pink looking -airborne -commonly grow in houses in places where phosphorous-containing materials or fatty substances accumulate. -appears in areas like showers and bathtubs, sinks, toilets, and pet water dishes. Serratia marcescens is -an opportunistic gram-negative pathogen -one of the main Enterobacteriaceae responsible for hospital-acquired infections. (due to its resistance to antibiotic therapy and other successful survival mechanisms) - Previously thought to be non-pathogenic -S. marcescens became a recognized name when consciously used in U.S. military experiments in the 1940s and 1960s. Symptoms -chilis -fever -shock -respiratory distress
