Distribution of hemolytic streptococci in respiratory specimens.
One hundred thirty-seven isolates of beta-hemolytic streptococci were recovered from 623 pharyngeal cultures. Twenty-nine percent of these were group A, 10% were group B, 31% were group C, 11% were group F, 12% were group G, and 7% could not be grouped. The significance of non-group A isolates in pharyngitis could not be evaluated in the absence of viral and serological studies. Hemolytic strep...
متن کاملGroup B beta-hemolytic streptococci causing pharyngitis.
Group B beta-hemolytic streptococci were isolated from the throats of 49 of 1,110 patients who had pharyngitis. Compared with patients whose throat cultures were negative for beta-hemolytic streptococci, those harboring group B were more likely to have enlarged tonsils (P less than 0.001), exudate (P less than 0.02), and tender enlarged anterior cervical lymph nodes (P less than 0.01). Group B ...

متن کاملTyping Group a Hemolytic Streptococci
Two methods of typing group A hemolytic streptococci have been described: slide agglutination and anti-M precipitin tests. The first, developed by Griffith (1), is more extensively used. I t has the distinct advantages of requiring small amounts of serum and culture, and of a quick reaction time when all conditions are favorable. I t has certain disadvantages: The granular growth of some strain...
متن کاملevaluation of bacitracin disk for the identification of group ‘a’ beta-hemolytic streptococci
a total of 711 beta-hemolytic streptococci were isolated from throat cultures of patients during 1970-73. these strains were grouped in parallel by the precipitin and bacitracin paper disk method. the former method was established as the standard by which the bacitracin technique was compared. the difference in results was about 5.67%. the greatest error (5.4%) was seen with non-group a strain...
