Identification of Staphylococcus aureus depends on demonstration of either coagulase, thermonuclease or protein A. Another possibility is afforded by measuring the affinity of Staph. aureus for fibrinogen with a passive haemagglutination technique. The proposed test can detect 98.8% of Staph. aureus strains. The validity of the test described was confirmed by using strains in primary culture on inhibitory media and methicillin‐resistant strains. Under these conditions the test was more reliable than the coagulase test.
