Etymology: "Serotyped" is the past tense and past participle of "serotype," a verb meaning to classify a microorganism or cell by its antigenic markers, the molecular features that the immune system recognizes. The verb is built from two parts: "sero-," from "serum," referring to the blood-derived fluid in which these reactions are tested, and "-type," from the Greek "typos," meaning impression or mark, which gives us "type" in its general sense of a class defined by a shared pattern. Put together, a serotype is a class of organisms distinguished by the markers found on their surface. To serotype something is therefore to test it against antibodies and see which markers react, then sort it into the group those reactions define. Researchers use this to tell apart strains of bacteria or viruses that look identical under a microscope but differ in their surface antigens, which can matter greatly for vaccines and disease tracking.
