Staphylococcus aureus is an etiological agent of a wide variety of human and animal infections. The majority of S. aureus are coagulase-positive; however, some may be atypical in that they do not produce coagulase. Incorrect identification of an isolate can impact implementation of effective treatment and/or control measures. In this study, polymerase chain reaction based DNA fingerprinting was used to differentiate coagulase-positive Staphylococcus aureus (CPSA) from coagulase-negative Staphylococcus aureus (CNSA). A total of 29 CNSA and 50 CPSA were evaluated. PCR-based DNA fingerprinting differentiated CNSA from CPSA on the basis of visible observation and densitometric evaluation. The method is rapid and accurate, eliminating variability associated with conventional techniques.
