Rapid grouping of beta-hemolytic streptococci by latex agglutination.
Latex agglutination was compared with fluorescent-antibody staining with group A conjugate and Lancefield precipitation for grouping of beta-hemolytic streptococci. Latex agglutination correctly grouped 98.8% of 82 group A streptococci and more than 95% of 187 group B, C, or G streptococci. Occasional cross-reactions occurred between groups A and C and groups B and G.
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...
متن کاملBacitracin and coagglutination for grouping of beta-hemolytic streptococci.
Bacitracin may be used for presumptive differentiation of group A from other beta-hemolytic streptococci. Whatever criteria are used for the test, a small number of erroneous results will be obtained. With the 1,161 strains studied in this laboratory, using a zone of 10 mm or greater as indicative of group A was better than using Maxted's original criterion of any zone of inhibition for group A...
متن کاملDifferentiation of group A from other beta hemolytic streptococci with bacitracin.
In the study of upper respiratory infections, nose and throat cultures for beta hemolytic streptococci3 are essential. Since group A streptococci are implicated in human respiratory infections more than other groups, it is important that streptococci recovered on culture be identified as belonging to group A or not. The finding of streptococci which belong to groups other than A in the nose or ...
