A small series of children undergoing intensive chemotherapy for staphylococcal disease were followed with respect to serum anticoagulase levels. The majority showed no appreciable neutralizing antibody versus any of a battery of 15 coagulases prepared from "standard" strains of staphylococci representing several phage groups. Three individuals exhibited relatively high (and in one instance a significantly rising) titer versus coagulase derived from the etiologic organism or from strains of closely related phage types. These antibodies were possibly the result of a prolonged initial episode of exposure to a single strain of staphylococci.
