In a prospective study, the prevalence of infection with Chlamydia trachomatis and Ureaplasma urealyticum was evaluated in the semen of 92 asymptomatic male partners of infertile couples using polymerase chain reaction and culture, respectively. The results were compared with the detection of serologically specific antibodies. U. urealyticum and C. trachomatis were detected in 12 (13%) and 10 (...

Ureaplasma spp. cause several disorders, such as nongonococcal urethritis, miscarriage, and preterm delivery with lung infections in neonates, characterized by pathological chorioamnionitis in the placenta. Although reports on antibiotic resistance in Ureaplasma are on the rise, reports on quinolone-resistant Ureaplasma infections in Japan are limited. The purpose of this study was to determine...

A modification of enzyme-linked immunosorbent assay (ELISA) was developed for the serological characterisation and identification of strains of Ureaplasma urealyticum. The eight recognised human serotypes of U urealyticum and antisera produced against them were used as reference for the evaluation and standardisation of the method. The serological profile illustrating reactions of antigen with ...

The presence of the tet(M) determinant and conjugative transposons related to Tn1545 in urogenital pathogens, Bacteroides ureolyticus (10 strains), Neisseria gonorrhoeae (37 strains) and Ureaplasma urealyticum (81 strains), was studied by PCR analysis and hybridization assay. All tetracycline-resistant strains that hybridized with a probe specific for tet(M) gave the expected fragment when thei...

The aim of the present study was to determine the association between the presence of Ureaplasma urealyticum in endotracheal aspirates and bronchopulmonary dysplasia (BPD). In addition, a review of similar studies from the English literature is presented. During the period February 1990 until March 1991, 108 mechanically-ventilated infants were included in a prospective study. Endotracheal aspi...

conclusions according to the direct correlation between the increase in the prevalence rate of genital mycoplasmas and increased age of pregnancy, initially, it is better to prevent pregnancy at older ages, and then, should a pregnancy occur, the highest levels of health cares should be provided to older pregnant women. materials and methods three hundred and fifty high vaginal swabs were taken...

All of five lyophilised cultures of Mycoplasma orale kept for 23 years at room temperature were still viable, as were all but one of 12 lyophilised cultures of six Mycoplasma spp. that had been stored for 18-22 years at 4 degrees C. Similarly, 11 of 13 lyophilised ureaplasma cultures were viable after 8-22 years at 4 degrees C; the titre of organisms in the viable cultures had diminished no mor...

Background Reactive arthritis, Reiter’s syndrome is one of the seronegative arthropathies, that can be associated with intestinal infections (Shigella, Salmonella, Yersinia, Campylobacter jejuni, Clostridium difficile), sexual infections (Chlamydia trachomatis, Ureaplasma urealyticum) and lung infections (Chlamydia pneumoniae, Mycoplasma pneumoniae). Reiter’s syndrome is an arthritis that occur...
