The phosphatase activity of coagulase‐positive Staphylococcus aureus strains isolated from patients and healthy persons

Enzymatic Activity of Coagulase-positive <i>Staphylococcus aureus </i>Strains Isolated from Patients and Healthy Carriers

“…It has also been shown that the activity of these enzymes is closely correlated with that of coagulase (5). Later Pan and Blumentlml (31) described the correlation of acid phosphatase activity and phage type and we demonstrated that strains isolated from healthy carriers produced considerably less phosphatase than those from cases of septicaemia and pyaemia and as well as from furunculosis (17). Moreover the activity of strains from septicaemia and pyaemia was generally somewhat greater than that of the strains from furuncles.…”

“…reactions were more frequently positive in strains isolated from patients than in those from healthy carriers (5,22,23). K('dzia found that strains from patients produced more acetoin (15) and showed greater acid phosphatase activity (17), had more intense endogenous respiration (16) as well as respira tion in the presence of some of the exogenic substrates (18), ac cumulated more free amino acids within the cell and produced more both protein and mucopeptide substances than strains iso lated from healthy school children (18). It appears from these results that virulent staphylococci are biochemically more active than avirulent ones.…”
