PURPOSE To evaluate the incidence of genitourinary mycoplasmas and the efficacy of antibiotics in women with overactive bladder (OAB) symptoms. MATERIALS AND METHODS Women with OAB symptoms (micturition ≥8/24 hours and urgency ≥1/24 hours) for ≥3 months were screened for Mycoplasma hominis (M. hominis), Ureaplasma urealyticum (U. urealyticum), and Chlamydia trachomatis (C. trachomatis). Speci...

The aim of this study was to evaluate the occurrence of genital mycoplasmas, especially Ureaplasma parvum and Ureaplasma urealyticum, in women with atypical squamous cells of undetermined significance (ASCUS), low grade squamous intraepithelial lesions (LSIL) and high grade squamous intraepithelial lesions (HSIL), compared to women with normal cytology living in Katowice, Poland. Two sterile sw...

Ureaplasma urealyticum is a pathogenic ureolytic mollicute which colonizes the urogenital tracts of humans. A genetic polymorphism between the two biotypes of U. urealyticum at the level of the urease genes was found. The urease gene cluster from a biotype 1 representative of U. urealyticum (serotype I) was cloned and sequenced. Seven genes were found, with ureA, ureB, and ureC encoding the str...

Chlamydia trachomatis, Mycoplasma hominis y Ureaplasma urealyticum colonizan, principalmente, el tracto genital se han asociado a diversas enfermedades como: endometritis, corioamnionitis, ruptura prematura de membranas, muerte fetal, entre otras. Este estudio descriptivo corte transversal tuvo como objetivo la detección C. M. U.urealyticum en muestras endocervicales mujeres 18 50 años atendida...

Corynebacterium jeddahense sp. nov., strain JCB(T), is the type strain of Corynebacterium jeddahense sp. nov., a new species within the genus Corynebacterium. This strain, whose genome is described here, was isolated from fecal flora of a 24-year-old Saudi male suffering from morbid obesity. Corynebacterium jeddahense is a Gram-positive, facultative anaerobic, nonsporulating bacillus. Here, we ...

The roles of Mycoplasma genitalium and Ureaplasma urealyticum in nongonococcal urethritis are not yet well established. The aim of this study was to determine the presence of these microorganisms in the urethral tracts of 187 human immunodeficiency virus type 1 (HIV-1)-infected male patients with no clinical signs of urethritis. The results indicate that the prevalence of M. genitalium and U. u...

Ureaplasma urealyticum has been associated with urethritis in men, obstetric problems in women, and respiratory distress syndrome in preterm infants. U. urealyticum can be divided into two biovars comprising 14 serovars. Partial sequences of genes encoding the multiple-banded antigens of the cell surface are known. Using a commercially available precast DNA mutation detection gel system, we hav...

Three glutamic-acid-producing coryneform strains were isolated from soil and vegetable samples. Chemotaxonomic investigations indicated that these strains belonged to the genus Corynebacterium. Phylogenetic studies, based on 16S rDNA analysis, demonstrated that the three strains formed a distinct cluster within the genus Corynebacterium and that their nearest relatives were Corynebacterium glut...

The existence of unusual colonies of Ureaplasma urealyticum (T mycoplasmas) in primary agar cultures of certain urine specimens is reported and their morphology is illustrated.

In an attempt to screen out new potent antimicrobial substances producing bacteria, Corynebacterium kutscheri NB-1 and Corynebacterium xerosis NB-2 were isolated and were found antagonistic to bacteria and fungi. Antimicrobial substances production of the bacterial strains was greatly influenced by variation of carbon sources. Galactose and glucose strongly enhanced the antimicrobial activity o...
