The isolation rate of Ureaplasma urealyticum was 57 per cent. from 47 patients with non-gonococcal urethritis, 40 per cent. from forty patients with gonorrhoea, 47 per cent from healthy sailors, and 53 per cent. from healthy students and laboratory technicians. No difference in distribution of eight serotypes among 45 isolates from these groups was demonstrated and no particular serotype could ...

Ciprofloxacin was evaluated in chlamydial infections of the urogenital tracts of women treated with a dosage regimen of 500 mg orally twice a day for seven days. Of the 40 women evaluated, 30 were infected with Chlamydia trachomatis only, two were infected with Neisseria gonorrhoeae only, and a further eight had combined gonococcal and chlamydial infections. Ten were found to be harbouring Chla...

Color change of pH indicators in broth medium is commonly used to quantify growth of ureaplasmas. These organisms differ from other members of the Mollicutes by their ability to hydrolyze urea to CO2 and NH3. This study describes a method which continuously monitors color change in ureaplasmal broth cultures. Using this technique we found: (i) there was a pH-dependent absorbance at 554 nm in ur...

Chronic lung disease (CLD) of prematurity is an inflammatory disease with a multifactorial etiology. The importance of Ureaplasma urealyticum in the development of CLD is debated, and steroids produce some improvement in neonates with this disease. In the present study, the capability of U. urealyticum to stimulate rat alveolar macrophages to produce nitric oxide (NO), express inducible nitric ...

The cervicovaginal and endometrial isolation rates of Ureaplasma urealyticum and Mycoplasma hominis and relevant demographic data were obtained at the time of laparoscopy in 193 women from infertile marriage. For comparative purposes, fertile women undergoing laparoscopy for tubal ligation (n = 56) or other purposes (n = 64) were also cultured. Blacks were more likely than caucasians to be infe...
