title: TYPING GROUP A HEMOLYTIC STREPTOCOCCI BY M PRECIPITIN REACTIONS IN CAPILLARY PIPETTES.
abstract: A method is described for performing type-specific anti-M precipitin tests on group A hemolytic streptococci in 1 mm. capillary pipettes. These tests require so much less precipitating serum than was formerly used that the method now seems to be practical.
