Throat swabs from 334 patients, submitted to the clinical laboratory of the Institute of Infectious Diseases (Siena University), for isolation of beta-hemolytic streptococci, were inoculated and incubated aerobically and anaerobically. Beta-hemolytic streptococci were identified in 117 (35%) cases, including 77 group A streptococci. Group A streptococci were recovered significantly more often with anaerobic incubation than with aerobic incubation (77 versus 53 cases: P less than 0.01). Non-group A beta-hemolytic streptococci also were recovered significantly more often with anaerobic incubation (40 versus 22; P less than 0.01). We conclude that anaerobic incubation for throat cultures is superior to incubation in normal air for detection of beta-hemolytic streptococci.

D013291	Streptococcus	A genus of gram-positive, coccoid bacteria whose organisms occur in pairs or chains. No endospores are produced. Many species exist as commensals or parasites on man or animals with some being highly pathogenic. A few species are saprophytes and occur in the natural environment.
D014069	Tonsillitis	Inflammation of the tonsils, especially the PALATINE TONSILS but the ADENOIDS (pharyngeal tonsils) and lingual tonsils may also be involved. Tonsillitis usually is caused by bacterial infection. Tonsillitis may be acute, chronic, or recurrent.	Tonsillitides
