Bacteriologic and serologic findings in experimental pyelonephritis caused by Ureaplasma urealyticum.
A challenge procedure based on reflux of Ureaplasma urealyticum to the rat kidney was used to examine the disease-causing potential of this species for the upper urinary tract. Renal infection was detected 8 days after challenge in 90 to 100% of animals exposed to 10(7) ureaplasmas but was not detected in animals exposed to fewer than 10(6) microorganisms. Viable microorganisms were recoverable...
متن کاملIntrarenal abscesses due to Ureaplasma urealyticum in a transplanted kidney.
A young woman developed multiple abscesses in her transplanted kidney. Amplification of the 16S rRNA gene with subsequent sequencing revealed Ureaplasma urealyticum as the infectious agent. Microbiological diagnosis and sensitivity testing led to therapy with levofloxacin, resulting in rapid recovery of the patient.
متن کاملUreaplasma urealyticum Causes Hyperammonemia in an Experimental Immunocompromised Murine Model
Hyperammonemia syndrome is an often fatal complication of lung transplantation which has been recently associated with Ureaplasma infection. It has not been definitely established that Ureaplasma species can cause hyperammonemia. We established a novel immunocompromised murine model of Ureaplasma urealyticum infection and used it to confirm that U. urealyticum can cause hyperammonemia. Male C3H...
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...
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...
