Variable antigens of Ureaplasma urealyticum containing both serovar-specific and serovar-cross-reactive epitopes.
Currently there are 14 recognized serovars of Ureaplasma urealyticum, and it has been postulated that only certain ones may be associated with disease and that lack of serovar-specific antibody may be an important risk factor. Unfortunately, ureaplasma antigens important in the human immune response and disease pathogenesis are poorly defined. By using sera from ureaplasma-infected patients and...
متن کاملCharacteristics of Ureaplasma urealyticum urease.
Sonication of Ureaplasma urealyticum cells grown in a dialysate growth medium effectively separated the cytoplasmic fraction from the membrane fraction, with both fractions relatively free from exogenous contaminating proteins. The urease activity was associated with the cytoplasmic fraction, and the ureaplasmal urease exhibited a specific activity higher than that of crystalline jack bean urea...

متن کاملInfection of the epididymis by Ureaplasma urealyticum.
Ureaplasma urealyticum organisms (ureaplasmas) were isolated from the urethra and epididymal aspirate of a man aged 24 who had acute right sided epididymitis. No other microorganisms were detected, and he had no chlamydial antibody response. A fourfold antibody response to the epididymal ureaplasma isolate was detected by two methods, however, and the patient responded clinically to doxycycline...
متن کاملAdherence of Ureaplasma urealyticum to human erythrocytes.
Ureaplasma urealyticum (four serotypes and two clinical isolates) were metabolically labeled with radioactive methionine to a high specific activity. Labeling allowed the study of the mechanism of adherence to human erythrocytes. The adherence mechanism was complex and partially mediated by proteinaceous surface components. The binding sites on the erythrocytes were partially sensitive to neura...
