Abstract

Group D streptococci were identified by slide co-agglutination and the results obtained were compared with conventional methods for the presumptive (bile esculin medium, salt tolerance) and confirmatory (Lancefield precipitin test, latex agglutination) identification of these bacteria. Of 137 clinical specimens examined, the co-agglutination procedure showed a 100% specificity and a 96.5–100% sensitivity (depending on the method of testing) in the identification of group D streptococci. The slide co-agglutination test was easy to perform and interpret and offers a valuable alternative to other less rapid techniques for the confirmatory identification of group D streptococci.
