OBJECTIVE Our goal was to determine the in vitro susceptibility of Ureaplasma urealyticum and Mycoplasma hominis isolates to several antibiotics in Argentina. METHODS Ninety-four strains of U. urealyticum and 18 strains of M. hominis isolated from cervical and urethral specimens were studied. Broth microdilution and agar dilution tests for minocycline, tetracycline, erythromycin, ciprofloxaci...

Sulfoglycolipids are ubiquitous components of the male germ cell membrane. Sulfogalactoglycerolipid (SGG) is restricted to mammalian cells and has recently been implicated in sperm/egg interactions. Mycoplasma infections have been implicated in infertility in a variety of species, including humans. Four such species-specific mycoplasmas, Ureaplasma urealyticum and Mycoplasma hominis (humans), M...

Background: Bronchopulmonary dysplasia (BPD) is the second prevalent lung disease and one of the care challenges of premature newborns. Different risk factors play an important role in the development of this disease. Therefore, the aim of the present study was to investigate the relationship between colonization with Ureaplasma urealyticum and BPD.Methods: This prospective cohort study w...

There is good evidence that the organism currently known as Ureaplasma urealyticum should be divided into two species-U. parvum (previously U. urealyticum biovar 1) and U. urealyticum (previously U. urealyticum biovar 2). In this study, we designed a series of primers, targeting the 16S rRNA gene and 16S rRNA-23S rRNA intergenic spacer regions, the urease gene subunits, and the 5' ends of the m...

OBJECTIVE A sonographically short cervix is a powerful predictor of spontaneous preterm delivery. However, the etiology and optimal management of a patient with a short cervix in the mid-trimester of pregnancy remain uncertain. Microbial invasion of the amniotic cavity (MIAC) and intra-amniotic inflammation are frequently present in patients with spontaneous preterm labor or acute cervical insu...

We report the first case of naturally occurring fluoroquinolone resistance in Ureaplasma spp. from the United States. Resistance in this case probably developed as a result of mutations in the gyrA and parC genes of the DNA gyrase/topoisomerase IV complex that occurred in the presence of antimicrobial selective pressure.

BACKGROUND Detection of Ureaplasma, Mycoplasma and Candida spp. in the vagina during pregnancy has previously been associated with preterm birth (PTB). However, the prevalence of these microorganisms and the associated obstetric risks (likely to be population-specific) have not been determined in Australian women; furthermore, in the case of Ureaplasma spp., very few studies have attempted char...

A study was conducted to verify the presence of mycoplasmas and ureaplasmas DNA in sheep semen samples from the State of Pernambuco. The PCR assay was conducted of according with standard protocols with generic primers. Mollicutes DNA was detected in 26.0% and Ureaplasma spp. in 12.0% of semen samples.
