Application of the rapid lysine decarboxylase test for early isolation and detection of salmonellae in sewage and other wastewaters.

A method for early isolation and detection of salmonellae in sewage and other wastewaters by using the rapid lysine decarboxylase test as a single biochemical reaction for screening the suspected Salmonella colonies is described. By this method, Salmonella isolation and identification can be completed within 2 to 3 days in contrast to the 5 to 7 days required for the conventional method.
