Identification of Streptococci in a Medical Laboratory

J Appl Bacteriol. 1984 Aug;57(1):1-14. doi: 10.1111/j.1365-2672.1984.tb02351.x.


A total of 965 cultures of streptococci received at a reference unit for identification were examined with API-20 Strep kits and also by established methods. The API method, although it needed to be supplemented with additional tests, largely overcame the difficulty that pyogenic streptococci are usually identified by their serological reactions and that biochemical tests are used for the identification of the other streptococci. Representatives of at least 24 established or possible species were identified.
