The Caenorhabditis elegans, a small worm called a nematode, scurrying across a Petri dish has helped lead to discoveries about community-associated MRSA (methicillin-resistant Staphylococcus aureus). “In the last year this organism has killed more people in the United States than AIDS,” said Kathleen Dannelly, an Indiana State University associate professor of biology leading the community-associated MRSA study. “It’s going to get worse.”
