Beta-SSA Agar is used with blood for the selective isolation of group A streptococci. Group A streptococcal infections are the most common cause of bacterial pharyngitis in children 5 to 10 years old. Beta-SSA Agar is a highly selective agar developed for the isolation of group A beta-hemolytic streptococci. The selective agents in the medium inhibit Gram-negative bacteria and most Gram-positive bacteria, although some strains of group B beta-hemolytic streptococci may grow. Beta-SSA Agar is supplemented with 5% sheep blood to detect hemolytic patterns of streptococci.
