title: Trioleoylglycerol lipolysis by Staphylococcus aureus strains from recurrent furunculosis, pyomyositis, impetigo and osteomyelitis.
abstract: Staphylococcus aureus strains isolated from 94 patients with recurrent furunculosis, chronic osteomyelitis, tropical pyomyositis and impetigo were investigated for lipase activity after growth 1, 2 and 5 days in aerated casein hydrolysate-yeast extract. As substrate for lipase activity a tri-3H-oleoylglycerol emulsion was used. Phage group II staphylococci isolated from furunculosis had the highest lipase activity and on day 5 these strains differed significantly in activity from strains isolated from the other infections. Strains isolated from impetigo had a remarkably low lipase production. The quantitative difference in lipase production of various S. aureus strains may reflect the localization of the lesion.
