Streptolysin-O (SLO) is a thiol-activated, membrane-damaging protein toxin of Mr 69,000 that is produced by most strains of beta-hemolytic group A streptococci. Native, primarily water-soluble toxin molecules bind to cholesterol-containing target membranes to assemble into supramolecular curved rod structures (25 to 100 nm long by ca. 7.5 nm wide), forming(More)
We have evaluated the diagnostic value of the fecal elastase test in comparison with the secretin-pancreozymin test in the diagnosis of exocrine pancreatic insufficiency. Pancreatic elastase was measured immunologically. Immunoreactive elastase activity in spot stools from controls ranged from 136 to 4440 microgram/g; 95% of all values were within 175 to(More)
Rabbit or human erythrocytes lysed with Staphylococcus aureus alpha-toxin were solubilized with Triton X-100, and the toxin was subsequently isolated by gel chromatography, sucrose density gradient centrifugation, and reincorporation into liposomes. In the presence of Triton X-100, the toxin exhibited a sedimentation coefficient of 11S and eluted at a(More)
Streptolysin-O was isolated from culture supernatants of group-A beta-hemolytic streptococci (Richards strain) by ammonium sulfate and polyethylene glycol precipitation, DEAE-ion exchange chromatography, preparative isoelectric focusing, and chromatography on Sephacryl S-300. Two forms of the toxin possessing similar hemolytic capacity were identified. The(More)
The aim of this study was to determine the incidence of oral/intestinal Candida colonization and Candida-antigen/antibody in immunosuppressed children after HTx (group III, n = 31), in children with CHD (group II, n = 24) and in children with healthy hearts (comparison group, group I, n = 23) aged 2-16 yr according to their dental status between 2004 and(More)
A chymotrypsin-like protease was detected along with elastase 1 in pancreatic secretion and stool. This enzyme was isolated from necrobiotic human pancreas, purified, partially characterized and designated as chymotrypsin B. Quantitative studies by rocket immunoelectrophoresis indicated that neither elastase 1 nor chymotrypsin B was degraded during(More)
Prostatic aspergillosis is a rare finding with only ten cases reported previously. We report the first case of systemic aspergillosis predominantly presenting with prostatic involvement and, clinically, with urinary retention in an immunocompetent host. Routine transurethral resection was performed due to benign prostatic hyperplasia with subvesical(More)
The measurement of fecal elastase 1 concentrations by means of an ELISA based on monoclonal antibodies (mABs) highly specific for human elastase 1 (ELISA 1) has become an accepted indirect test of the exocrine pancreatic function during the last years. Its use has been demonstrated in many clinical studies including comparison with direct function tests and(More)
The emergence of resistance during therapy and the efficacy of different antibiotic therapy regimens were studied in 38 intensive care patients suffering from pulmonary infections caused by Enterobacter cloacae. Every three days a fresh isolate was obtained from each patient and tested in vitro for susceptibility to 16 antibiotics by determination of the(More)
The determination of faecal pancreatic elastase 1 is a reliable test for the diagnosis of chronic pancreatic diseases in man due to its high sensitivity and specificity (93%). A clinical study was performed to investigate the detectability of canine faecal pancreatic elastase with polyclonal anti human pancreatic elastase 1 antibodies in 52 dogs with(More)
