BACKGROUND Mycoplasma hominis and Ureaplasma urealyticum are important causative agents of vaginitis, cervicitis, postpartum sepsis, reproductive infections and infertility in both males and females. OBJECTIVES According to the uncertain prevalence of U. urealyticum and M. hominis in Iranian infertile females, the present study was carried out to determine the prevalence of U. urealyticum and...
Ureaplasma species commonly colonize the adult urogenital tract and are implicated in invasive diseases of adults and neonates. Factors that permit the organisms to cause chronic colonization or infection are poorly understood. We sought to investigate whether host innate immune responses, specifically, antimicrobial peptides (AMPs), are involved in determining the outcome of Ureaplasma infecti...
In this study, we evaluated the usefulness of a culture system used in our laboratory for the detection of Ureaplasma urealyticum in the endotracheal aspirates of neonates. Ureaplasmal broth was used to enhance the growth of U. urealyticum followed by observation of colonies on A7 agar. Of the 68 samples of endotracheal aspirates tested, 60 gave positive indication of urease activity by the bro...
A PCR assay, using three primer pairs, was developed for the detection of Ureaplasma urealyticum, parvo biovar, mba types 1, 3, and 6, in cultured clinical specimens. The primer pairs were designed by using the polymorphic base positions within a 310- to 311-bp fragment of the 5' end and upstream control region of the mba gene. The specificity of the assay was confirmed with reference serovars ...
BACKGROUND AND OBJECTIVES Mycoplasma hominis and Ureaplasma urealyticum are important opportunistic pathogens that cause urogenital infections and accelerated newborn delivery in pregnant women. Moreover genital mycoplasmas have been implicated in different neonatal diseases such as pneumonia, sepsis and meningitis. This study was conducted to find out the prevalence and transmission rate of th...
Antisera prepared against the eight recognized serotypes of Ureaplasma urealyticum were tested against the homologous and heterologous antigens by a modified metabolic inhibition test that used bromothymol blue broth in microtiter plates. The method gives clear endpoint determinations which are usually maintained on continued incubation. Antisera against serotype 8 showed cross-reactions with t...
Inoculation of the urethra, conjunctiva, pharynx, and anal canal of six male crab-eating macaques (Macaca fascicularis) with urethral exudate from male patients with urethral gonorrhoea or with laboratory gonococcal strains was unsuccessful in establishing infection or producing increased polymorphonuclear leucocytes on Gram stain. Intraurethral inoculation with laboratory strains of Ureaplasma...
Recent work on the Molicutes that associate with genital tract tissues focuses on four species that may be of interest in potential maternal, fetal, and neonatal infection and in contributing to adverse pregnancy outcomes. Mycoplasma hominis and Ureaplasma urealyticum have historically been the subject of attention, but Mycoplasma genitalis which causes male urethritis in addition to colonizing...
We designed primers and probes for the detection and discrimination of Ureaplasma parvum and U. urealyticum and their 14 serovars by real-time PCR. The analytical sensitivity and specificity of the multiplex species-specific PCR were determined by testing corresponding American Type Culture Collection (ATCC) type strains, 47 other microbial species, and human genomic DNA. The limits of the mult...
