| Lancefield classification | A serologic classification dividing haemolytic streptococci into groups (A to O) which bear a definite relationship to their sources, based upon precipitation tests depending upon group-specific substances that are carbohydrate in nature; e.g., Group A contains strains pathogenic for man; B, strains from mastitis in cows and from normal milk, including a few strains from the human throat and vagina; C, strains from various lower animals, including a number from cattle; D, strains from cheese; E, strains from certified milk; F, strains mainly from the human throat, associated with tonsillitis; G, strains from man, a few from monkeys and dogs; and H, K, and O, nonpathogenic strains from normal human respiratory tracts.

| Lancefield c. |
a serologic classification of the hemolytic streptococci, based on extraction and examination by a precipitin technique of group-specific carbohydrate antigens contained in the cell wall. Groups A through O have been established.

| Lancefield precipitation t. |
a ring precipitation test used to classify and identify streptococci. Group-specific antibody reacts in vitro with group-specific polysaccharide to produce a ring of precipitation where the two reagents react at the interface.
