Endogenous activities of phospholipases A and C in Ureaplasma urealyticum were assayed in cellular fractions of exponential-phase cells. Enzymatic studies indicated that ATPase activity was localized in the plasma membrane fraction and NADH and NADPH dehydrogenase activities were localized in the cytosol fraction. Studies with purified ureaplasma membranes demonstrated that, of three serovars t...

In this study, the phylogenetic relationships between the two biovars and 14 serovars of Ureaplasma urealyticum were studied using the sequences of four different genes or genetic regions, namely: 16S rRNA genes; 16S-23S rRNA gene spacer regions; urease gene subunits ureA, ureB, partial ureC and adjoining regions upstream of ureA, ureA-ureB spacer and ureB-ureC spacer; the 5'-ends of the multip...

Genital Ureaplasma urealyticum infection is considered to be a sexually transmitted infection. The bacterium has been found to be involved in PID, chorioamnionitis, urethritis, respiratory distress syndrome and pneumonia in newborn, abortion and infertility. U. urealyticum infections not only jeopardize fertility but also pose a risk for infertility treatment and resulting pregnancies. The purp...

The in vitro activity of trovafloxacin against 125 strains of Mycoplasma species and Ureaplasma urealyticum, including fluoroquinolone-susceptible and fluoroquinolone-resistant species, was compared to those of other fluoroquinolones, doxycycline, and erythromycin. The MIC at which 90% of isolates are inhibited for all fluoroquinolone-susceptible strains was 0.25 microg/ml. Whatever the associa...

background: prostate cancer (pca) is an important health problem in the aging male population in the world. it is the third most common cancer in the world. despite of its importance, relatively little is known about its etiology. sexually transmitted infections (sti) and urogenital pathogens such as mycoplasma and ureaplasma, have been proposed as a risk factor for prostate cancer development....

Ureaplasma urealyticum was isolated from the endotracheal aspirates of 39 (21.4%) of 182 neonates with respiratory distress requiring ventilatory support. Mycoplasma hominis was isolated from one (0.5%) neonate. Bacterial cultures were negative in 123 (67.6%) neonates. Antibiotic susceptibility test carried out on ten isolates of U. urealyticum showed that all the organisms were sensitive to er...

Persistent infectious polyarthritis caused by Ureaplasma urealyticum in a patient with common variable hypogammaglobulinaemia is described. The patient developed a symmetrical, destructive polyarthritis and tenosynovitis associated with a markedly depressed synovial fluid glucose concentration and characteristic soft tissue abscesses. The ureaplasma organism developed resistance to multiple ant...
