A serological test in the diagnosis of staphylococcal infection.

The diagnosis of occult staphylococcal infection of bone is often difficult. Two cases are presented that illustrate the use of the anti-alpha haemolysin titration. In the second case this test appears to have been of value as a guide to effective chemotherapy. Such cases are now infrequent and we publish these results in the hope that further knowledge of the efficiency of this test may be sought elsewhere.
