Pan, Yue-Liang(University of Michigan Medical School, Ann Arbor),and Harold J. Blumenthal. Correlation between acid phosphatase and coagulase production or phage type ofStaphylococcus aureus. J. Bacteriol.82:124–129. 1961.—A quantitative assay of acid phosphatase in 26 coagulase-negative and 73 coagulase-positive strains ofStaphylococcus aureuswas performed using an assay procedure modified to estimate extracellular, as well as the cellular, phosphatase. Some of the factors affecting the formation of acid phosphatase were studied. On the average, coagulase-negative strains produced 4.0 units and coagulase-positive strains 19.6 units although some negative strains produced more phosphatase than positive strains. More phosphatase was produced by strains of phage-group I than by strains of any other group.
