Abstract:
Abstract Genital tract ureaplasma infections are associated with numerous complications, ranging from inflammation, through infertility, to problematic pregnancy. In the course of ureaplasma infection, the risk of human papillomavirus infection increases. Diagnostic tests for urea-plasma infections are not always carried out, especially in women with the normal Nugent test results. The study attempts to check whether it is possible to find a prognostic indicator that could suggest a high abundance of ureaplasmas (≥ 104 CFU/ml) at the stage of the initial examination of vaginal discharge. Such a prognostic factor could qualify women for further tests to detect infections with these atypical bacteria. Six hundred twenty-seven white women with a score of 0–3 on the Nugent scale were tested, including 322 patients with a high abundance of ureaplasmas (≥ 104 CFU/ml) and 305 who tested negative for these bacteria. Ureaplasma infections were detected statistically significant in women who had few or no epithelial cells in the genital swab specimens compared to the results obtained for women with numerous or very numerous epithelial cells (p < 0.001). The risk of the high density of ureaplasmas was 38.7% higher with fewer or no epithelial cells than with high numbers. In patients aged 18–40 years with few or no epithelial cells, a high density of ureaplasmas (≥ 104 CFU/ml) was observed significantly more frequently (p = 0.003). Determining the number of epithelial cells in Gram-stained slides may be the prognostic indicator of ureaplasma infection. Testing for genital ureaplasma infection should be considered, especially in women of childbearing age (18–40 years), even if the Nugent test value is normal and pH ≤ 4.6.

Abstract:
ABSTRACT The in vitro susceptibilities of 151 unique clinical isolates of Mycoplasma pneumoniae, Mycoplasma hominis, Mycoplasma fermentans, Mycoplasma genitalium, and Ureaplasma species to DC-159a, an investigational fluoroquinolone, in comparison with those to other agents were determined. Macrolides were the most active agents against M. pneumoniae and M. genitalium, whereas clindamycin was most active against M. hominis. DC-159a MICs were ≤0.5 μg/ml for all Mycoplasma species and ≤4 μg/ml for ureaplasmas. DC-159a was the most active fluoroquinolone tested against M. pneumoniae and M. fermentans, and it was second to moxifloxacin against the other species. It was bactericidal against 10 M. pneumoniae isolates and demonstrated killing of ≥99.9% of the inoculum at 24 h for 2 isolates. The excellent in vitro activity of DC-159a demonstrates its potential for use in the treatment of infections due to mycoplasmas and ureaplasmas.

Abstract:
In 2000, the full genome sequence of Ureaplasma parvum (previously known as Ureaplasma urealyticum) serovar 3 was released. In 2002, after prolonged debate, it was agreed that the former U. urealyticum should be divided into two species – U. parvum and U. urealyticum. To provide additional support for this decision and improve our understanding of the relationship between these two species, the authors studied four ‘core’ genes or gene clusters in ATCC reference strains of all 14 serovars of U. parvum and U. urealyticum. These ‘core’ regions were the rRNA gene clusters, the EF-Tu genes (tuf), urease gene clusters and multiple-banded antigen genes (mba). The known U. parvum genome sequences (GenBank accession no. NC_002162) were used as reference. DNA insertions and deletions (indels) were found in all of the gene regions studied, except tuf, but they were found only between, not within, the two species. An incidental finding was that there was inter-copy heterogeneity for rRNA gene cluster sequences. Sequence analysis (sequence heterogeneity and especially indels) of all four selected targets consistently supported the separation of human ureaplasmas into two species. Except for multiple-banded antigen, there was less heterogeneity in amino acid sequences of proteins, between species, than in the nucleic acid sequences of the corresponding genes. The degrees of heterogeneity at the 5′ end of the species-specific regions of multiple-banded antigen were almost identical for both amino acid and nucleotide sequences. Analysis of the authors' results provided an interesting case study to help resolve some common problems in the use of sequence data to infer phylogenetic relationships and support taxonomic changes. It is recommended that, to avoid confusion, the new nomenclature be used for human ureaplasmas in future publications.

Abstract:
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. urealyticum was higher in AIDS patients than in asymptomatic, HIV-1-infected patients and in healthy individuals. The high rate of mycoplasmas and ureaplasmas detected in AIDS patients, in the absence of urethritis, argues against major roles in causing disease at the urethral mucosal level for these microorganisms.

Abstract:
The characteristics of the genital microflora of 70 non-pregnant women with non-gonococcal endocervicitis and 20 healthy women were characterized. In most cases of endocervicitis, a mixed infection was diagnosed, while chlamydia was most often detected in combination with herpes simplex viruses (HSV) and human papillomavirus (HPV). With monoinfection, ureaplasmas were more often found. In 20% of healthy women, ureaplasmas were detected in cervical samples. It was found that in 83% of cases of endocervicitis, the vaginal microflora is involved in the pathological process, and most often this is manifested by bacterial and candidal vaginitis. The leading etiological role in the development of endocervicitis in non-pregnant women belongs to ureaplasmas, chlamydia, HSV and HPV.

ABSTRACT The in vitro susceptibilities of 103 Mycoplasma pneumoniae isolates, 14 Mycoplasma hominis isolates, 12 Mycoplasma fermentans isolates, and 24 Ureaplasma species to ABT-773, an investigational ketolide, and seven other agents were determined. For M. pneumoniae, the ABT-773 MIC at which 90% of isolates are inhibited (MIC90; ≤0.001 μg/ml) was comparable to those of azithromycin, clarithromycin, and erythromycin and at least 128-fold lower than those of levofloxacin, gatifloxacin, moxifloxacin, and doxycycline. For M. fermentans, the ABT-773 MIC90 (≤0.008 μg/ml) was 2- to 128-fold lower than those of all other agents tested. For M. hominis, the ABT-773 MIC90 (0.031 μg/ml) was equivalent to that of moxifloxacin, 2-fold lower than those of gatifloxacin and clindamycin, and 16-fold lower than that of levofloxacin. ABT-773 was equally active against doxycycline-susceptible and doxycycline-resistant organisms. The ABT-773 MICs (0.016 μg/ml) for Ureaplasma species were the lowest of those of any drug tested. The MIC90 was 4- to 64-fold lower than those of clarithromycin, azithromycin, and erythromycin and ≥16-fold lower than those of all three fluoroquinolones. Minimal bactericidal concentrations determined for a subgroup of organisms were ≤0.063 μg/ml for M. pneumoniae and 0.25 μg/ml for M. fermentans, but they were several dilutions higher for M. hominis and Ureaplasma spp. ABT-773 has great potential for further study for the treatment of infections due to mycoplasmas and ureaplasmas.

Abstract:
ABSTRACT The in vitro susceptibilities to garenoxacin (BMS-284756), an investigational des-fluoroquinolone, and eight other agents were determined for 63 Mycoplasma pneumoniae, 45 Mycoplasma hominis, 15 Mycoplasma fermentans, and 68 Ureaplasma sp. isolates. Garenoxacin was the most active quinolone, inhibiting all isolates at ≤1 μg/ml. The garenoxacin MIC at which 90% of isolates are inhibited (MIC90s; ≤0.008 μg/ml) was at least 4-fold less than those of moxifloxacin and clindamycin, 8-fold less than that of sparfloxacin, and 64-fold less than those of levofloxacin and ciprofloxacin for M. pneumoniae. For M. hominis, the garenoxacin MIC90 (≤0.008 μg/ml) was 4-fold less than those of clindamycin and moxifloxacin, 8-fold less than that of sparfloxacin, and 64-fold less than those of levofloxacin and ciprofloxacin. All 15 M. fermentans isolates were inhibited by garenoxacin at concentrations ≤0.008 μg/ml, making it the most active drug tested against this organism. For Ureaplasma spp., the garenoxacin MIC90 (0.25 μg/ml) was equivalent to those of moxifloxacin and doxycycline, 4-fold less than those of levofloxacin and sparfloxacin, 8-fold less than that of azithromycin, and 32-fold less than that of ciprofloxacin. Garenoxacin and the other fluoroquinolones tested were demonstrated to have bactericidal activities against M. pneumoniae and M. hominis by measurement of minimal bactericidal activities and by time-kill studies. Further study of garenoxacin is required, as it has great potential for use in the treatment of infections due to mycoplasmas and ureaplasmas.

Abstract:
Group B streptococcus (GBS, S. agalactiae) and human ureaplasmas (U. parvumand U. urealyticum) are two clinically and phylogenetically related, potential perinatal pathogens. Their relationships between genotypes and pathogenesis of GBS and ureaplasma infection were still not well understood, one of the reason is that both of them are still short of a very practical genotyping system. In the study, to solve the above problem we developed genotyping systems for the organisms (the second section). For human ureaplasmas, based on four genes/gene clusters (rRNAgene clusters, the elongation factor Tu genes, urease gene complexes and multiplebanded antigen genes), we designed many primer pairs suitable for developing species identification assays for the two newly established human ureaplasma species (U. parvum and U. urealyticum). Further, based on the heterogeneity of ureaplasma multiple banded antigen gene (which contains species- and serovar-specific regions), we developed genotyping methods for each ureaplasma species.For GBS, based on three sets of molecular markers (capsular polysaccharidesynthesis gene clusters, surface protein antigen genes and mobile genetic elements),we developed a genotyping system. The primary evaluation of the genotyping systems showed that the genotyping systems were practical alternative assays for the conventional serotyping and they will be useful to further explore the relationships between genotypes and pathogenesis of GBS and ureaplasma infection. In the study, we introduced novel data and tools into GBS and ureaplasma studies especially from genomic- and bioinformatics-based molecular microbiology(the third section). For two newly established human ureaplasma species, based on the U. parvum serovar-3 genome, and using the above four important genes/geneclusters, we exposed some interesting problems in the understanding of newureaplasma taxonomy especially in the post genomic era. For GBS, we studied the two published full genomes and exposed some new problems or possible future new research fields. In particular we found the two finished and one ongoing GBS genomes were all non-typical and suggest that future genomic project had better have genetic population structure viewpoint. Finally, we suggested that integrated studies of the two potential or conditional perinatal pathogens, from the viewpoint of evolution, would provide a new understanding angle of the pathogenesis of the two organisms. Studies suggested that during coevolution, human ureaplasmas(especially U. parvum) became friendlier than their ancestors to their human host (by losing most of its virulence genes); however, GBS tried to increase its invasive abilities (by getting more virulence genes) to fight against the human host attack.

O desenvolvimento do câncer cervical depende da exposição ao HPV, fator necessário, mas não suficiente. Outras bactérias, tais como ureaplasmas, têm sido associadas como cofatores. O objetivo deste estudo foi avaliar a presença de ureaplasmas em mulheres com lesão cervical, e observar alterações em PHK causadas pela infecção por ureaplasmas. 140 swabs vaginais foram coletados. O material foi submetido a PCR para a detecção de HPV, Mollicutes, U. urealyticum, U. parvum e seus sorotipos, e outras bactérias de importância ginecológica; e qPCR para U. urealyticum e U. parvum. Também foi realizada a infecção de ureaplasmas em PHK transformados com HPV. As células foram contadas e realizou-se a dosagem das citocinas IL1-β, IL-6 e TNF-α. HPV, Mollicutes, U. parvum, sorotipos 1 e 6 de U. parvum, T. vaginalis e G. vaginalis, além de alguns fatores socioeconômicos, foram associados com lesão cervical. Verificou-se maior carga de U. parvum entre mulheres com lesão. Houve diminuição do número de células e maior liberação de IL-6 e TNF-α nos grupos infectados. Com os resultados obtidos neste estudo, foi possível verificar uma associação entre os ureaplasmas e HPV no início das lesões cervicais, contudo mais estudos precisam ser realizados para aprimorar essa hipótese.

Besides this, it was detected higher load U. parvum among women with injury. There was decrease in cell number and increased release of IL-6 and TNF-α in infected groups. With the results of this study, we found an association among HPV and ureaplasmas at the beginning of cervical lesions, but more studies are needed to enhance this hypothesis.

Abstract:
The Mycoplasma species Ureaplasma parvum and Ureaplasma urealyticum colonize the human adult urogenital tract and are not typically associated with disease. Perinatal transmission, however, has been implicated in the pathogenesis of preterm birth, chorioamnionitis, and other complications of extreme prematurity, including neonatal pneumonitis, bronchopulmonary dysplasia (BPD), meningitis, and necrotizing enterocolitis (NEC). This chapter reviews the biology of these organisms. Epidemiologic and experimental evidence supporting a role for ureaplasmas in the pathogenesis of neonatal disease, clinical manifestations of infection in the infant, current microbiologic diagnostic methods, and the present status of treatment options are reviewed. Macrolide antibiotic therapy is controversial for infected infants, and current concepts regarding candidates for treatment are discussed. Key unanswered questions that need to be addressed in future research studies are also suggested.

Abstract:
This chapter deals with mycoplasmas, which are the smallest free-living organisms and are unique among prokaryotes in that they lack a cell wall; this is largely responsible for their biologic properties and lack of susceptibility to many commonly prescribed antimicrobial agents. Mycoplasmas are usually mucosally associated, residing primarily in the respiratory and urogenital tracts and rarely penetrating the submucosa, except in the case of immunosuppression or instrumentation. The chapter analyzes the intracellular localization that occurs in some species, such as M. genitalium and M. pneumoniae, which contribute to the chronicity that characterizes many mycoplasmal infections. The chapter investigates several species of mycoplasmas and ureaplasmas for which humans and other animals are believed to be the primary host; disease often occurs in the setting of immunosuppression. It identifies five species responsible for the majority of clinically significant infections: M. pneumoniae, M. hominis, M. genitalium, Ureaplasma urealyticum, and U. parvum.

Abstract:
Mycoplasmas are the smallest self-replicating prokaryotes. They are devoid of cell walls, with the plasticity of their outer membrane favouring pleomorphism, although some have a characteristic flask-shaped appearance. Mycoplasmas recovered from humans belong to the genera Mycoplasma (14 species and one candidatus species) and Ureaplasma (two species). They are predominantly found in the respiratory and genital tracts, but sometimes invade the bloodstream and thus gain access to joints and other organs. Diagnosis is made by nucleic acid amplification tests and/or serology. Culture is slow and of limited value in clinical diagnosis. Apart from supportive care, treatment is usually with tetracyclines or macrolides, although an increasing prevalence of macrolide resistance is seen, primarily in Asia. There is no commercially available effective vaccine.

Abstract:
Introdução: A microbiota vaginal é um complexo sistema com diversidade de microrganismos. A disbiose parece aumentar o risco de infecções, principalmente as sexualmente transmissíveis, entre as quais por papilomavírus humano, agente associado a lesões cervicais. Objetivo: Avaliar os diferentes tipos de microbiota cervical e as suas características no esfregaço de material residual de citologia em meio líquido, associando com o papilomavírus humano e com Chlamydia trachomatis, Neisseria gonorrhoeae, Mycoplasma genitalium, Mycoplasma hominis, Ureaplasma urealyticum, Trichomonas vaginalis. Métodos: O estudo analisou 179 casos que tinham material residual de citologia em meio líquido. Alíquota do material foi colocado em lâmina adequada, fixado a seco e corado por método de Gram para leitura em microscópio óptico. Outra alíquota foi utilizada para estudo em reação em cadeia da polimerase - transcriptase reversa e multiplex para pesquisas dos microorganismos associados a infecções sexualmente transmissíveis. O teste exato de Fisher com intervalo de confiança foi utilizado para significância estatística. O projeto foi aprovado em comitê de ética sob número 24071519.9.0000.5049 (UniChristus). Resultados: Os casos foram divididos conforme o escore de Nugent aplicado a esfregaços corados pelo método de Gram. Em microbiota cervical normal (escores de 0 a 3), 100 casos (55,86%); em microbiota intermediária (escore de 4 a 6), 51 casos (28,5%); em sugestivo de disbiose (escore de 7 a 10), 28 casos (15,64%). Nos casos de disbiose, foram observados: Chlamydia trachomatis (1[3,57%]), Mycoplasma hominis (7[25%]), Ureaplasma urealyticum (1[3,57%]), papilomavírus humano 16/45 (1[3,57%]), papilomavírus humano de alto risco (AR) (3[10,71%]) e AR e 16/45 (1[3,57%]). No grupo normal, foi a seguinte distribuição: Ureaplasma urealyticum (1[1%]), papilomavírus humano 16 (2[2%]), papilomavírus humano 18/45 (3[3%]), AR (13[13%]). No grupo intermediário, a distribuição foi: Ureaplasma urealyticum (2[3,9%]), papilomavírus humano AR (5[9,8%]) e papilomavírus humano AR, 16 (1[3,9%]). A única diferença significativa foi de Mycoplasma hominis na disbiose (p<0,0001). Conclusão: O estudo não evidenciou uma associação maior no grupo de disbiose com a maioria das infecções sexualmente transmissíveis, no entanto, com Mycoplasma hominis, foi significativo.
