PURPOSE The aim of the study was to assess the incidence of Ureaplasma urealyticum (U. urealyticum) and Mycoplasma hominis (M. hominis) infection in women with urogenital diseases. MATERIAL AND METHODS M. hominis and U. urealyticum was assessed in 541 women from gynaecological and STD outpatient clinics, aged 18-55 years. A Mycoplasma IST 2 kit was used for biochemical determination of mycopl...

We describe 3 pediatric patients with cancer who had clinical and radiographic evidence of pneumonitis and for whom cultures of bronchoalveolar lavage fluid specimens yielded Ureaplasma urealyticum. Two of the patients died; for the surviving patient, clinical improvement coincided temporally with administration of erythromycin. Immunocompromised patients with pneumonitis of unclear etiology sh...

BACKGROUND/AIM To detect the effects on quinolone resistance due to biofilm formation activity in Ureaplasma urealyticum. MATERIALS AND METHODS An improved checkerboard dilution susceptibility test was used to analyze the quinolone resistance of clinical Ureaplasma isolates and a postbiofilm formation susceptibility assay was used to compare the effects on the quinolone susceptibility between...

In a prospective study of non-bacterial infection in a neonatal intensive care unit in north west London, Chlamydia trachomatis infection was identified in 4 of 280 babies (1.4%) and was the most common cause of neonatal ophthalmia. One of the four developed pneumonitis. Ureaplasma urealyticum was found to colonise the nasopharynx in 53 of 235 babies (22.6%), with Mycoplasma hominis present in ...

Epidemiologic studies indicated that some infertile men who were infected with Ureaplasma urealyticum displayed positive antisperm antibodies in their serum and/or semen. The purpose of this study was to investigate the possible mechanism of antisperm antibodies production after infection with U. urealyticum and to analyze the relationship between U. urealyticum and infertility. The existence o...

Sequencing of mba gene fragments of reference strains of Ureaplasma urealyticum serovars 1, 3, 6, 14 and 8, in addition to 33 clinical U. urealyticum isolates is reported. A phylogenetic tree deduced from alignment of these sequences clearly demonstrates two major clusters (confidence limit 100%), which equate to the parvo and T960 biovars, and five types, which have been designated mba 1, 3, 6...

BACKGROUND Ureaplasma urealyticum and its association with chronic lung disease (CLD) of prematurity has remained a controversial topic. To readdress this question, we performed a longitudinal study using culture and polymerase chain reaction to detect U urealyticum in the respiratory tract of very low birthweight infants throughout their neonatal intensive care unit hospitalizations. METHODS...

BACKGROUND Genital mycoplasmas colonise up to 80% of sexually mature women and may invade the amniotic cavity during pregnancy and cause complications. Tetracyclines and fluoroquinolones are contraindicated in pregnancy and erythromycin is often used to treat patients. However, increasing resistance to common antimicrobial agents is widely reported. The purpose of this study was to investigate ...

Ureaplasma urealyticum comprises 14 serotypes. The existing serotyping methods all use polyclonal antibodies. These methods are time-consuming and labor-intensive, and they cannot always be performed on primary isolates; in addition, the results are difficult to interpret. We developed a new enzyme-linked immunosorbent assay (ELISA) method using serotype-specific monoclonal antibodies (MAbs) to...
