Abstract
THE occurrence of streptococci of groups other than A is rare in upper respiratory infections such as scarlet fever, tonsillitis and septic sore throat. These streptococci, however, are frequently isolated from sporadic infections, including septic abortion (Hare,1 1937), puerperal fever (Fry,2 1938), meningitis (Rantz,3 1942), urinary infections (Porch,4 1941), subacute bacterial endocarditis (Wheeler and Foley,5 1945) and miscellaneous conditions (Wheeler and Foley,6 1943).
