Anti-gamma haemolysin as a diagnostic test in staphylococcal osteomyelitis.
The anti-alpha-haemolysin test is widely used in the diagnosis of staphylococcal osteomyelitis. An additional test would be welcomed because raised antibodies to this antigen are not seen in all proven cases. This communication reports that anti-gamma-lysin was present in the serum of most of the 19 patients with proven staphylococcal osteomyelitis studied here. In two cases followed up after c...
متن کاملPhysicochemical Studies on Human Plasminogen
Plasminogen (profibrinolysin) of high specific activity has been prepared from human sources and converted to plasmin (fibrinolysin) by a variety of means (3, 4). Since these preparations seemed to possess activities of as high an order as any that had yet been produced, it was considered appropriate to examine their purity by physicochemical means. Such investigations do not appear to have bee...
متن کاملStructural Studies on Polypeptide Hormones
The structures of three polypeptide hormones (glucagon, a 25-residue analogue of adrenocorticotropin, and parathyroid hormone) which contain enough residues to permit organization have been evaluated in aqueous solution by fluorescence and circular dichroism. The effects of pH, temperature, and guanidine on both tyrosyl and tryptophanyl emission have been measured. None of the fluorescence para...
متن کاملPurification and properties of staphylococcal delta hemolysin.
Large amounts (200 mg per liter of culture supernatant fluid) of highly purified staphylococcal soluble delta hemolysin were obtained by adsorption to and selective elution from hydroxyapatite followed by exhaustive dialysis against water, concentration by polyvinylpyrrolidone or polyethylene glycol 20,000 dialysis, and a final water dialysis. No carbohydrate, phosphorus, or inactive 280-nm abs...
متن کاملStudies on the Pathogenesis of Staphylococcal Infection
Necrosis of rabbit skin produced by thermal injury was found to result in a striking increase in local infectivity of staphylococci that were coagulase-positive and hemolytic, but no local increase in the infectivity of non-pathogenic staphylococci. Infection produced in necrotic burns extended beyond the area of burn and was characterized by hemorrhage, edema, and necrosis of contiguous normal...
