✦ Synopsis

Despite some similarities, L-streptococci could be clearly differentiated from A-streptococci. Formamide, autoclaved and nitrous acid extracts of all L-streptococcal cultures studied reacted only with their specific antisera and did not cross-react with any other group specific streptococcal antigens. All 33 L-streptococcal cultures, in contrast to A-streptococci, produced ~-D-glucuronidase and/3-D-galactosidase, hydrolyzed Na-hippurate, grew on 10% and 40% bile blood agar and were agglutinated by the lectin of Aracbis bypogaea. Some differences between A-and L-streptococci were also observed in their sensitivity patterns to bacitracin and sulfamethoxazol-trimethoprim.
