[Identification of strains of beta-hemolytic streptococci of groups A, B, C, and G by coagglutination].
A study was conducted on the coagglutination (CoA) technique in the serogrouping of betahemolytic streptococci of the groups A, B, C and G, previously identified by physiological tests and the agar immunodiffusion technique. This technique was used as a reference test and, according to its results, it can be stated that the CoA technique allowed for the serological grouping in 95.7% of the strains. The CoA technique was assessed by using reactions prepared in our laboratories and the commercial kit Phadebact.
