1. Qual o melhor tratamento para Gardnerella vaginalis?
A Gardnerella vaginalis é uma bactéria que habita a região íntima feminina. Normalmente se encontra em concentrações muito baixas, não produzindo qualquer tipo de problema ou sintoma. Quando as concentrações de Gardnerella sp. aumentam, devido a fatores que possam interferir no sistema imunológico e microbiota genital (higienização incorreta,

2. Main etiological agents identified in 170 men with urethritis attended at the Fundação Alfredo da Matta, Manaus, Amazonas, Brazil,
Abstract Background: Sexually transmitted infections (STI) are a global public health problem. Urethritis are among the most common STIs, and can cause several complications and facilitate the transmission of the HIV virus. Objectives: To investigate the main etiologic agents of urethritis in 170 men treated at Fundação Alfredo da Matta. Methods: To ide

3. Antimicrobial (including antimollicutes), antioxidant and anticholinesterase activities of Brazilian and Spanish marine organisms – evaluation of extracts and pure compounds
Abstract This work describes the antimicrobial, antioxidant and anticholinesterase activities in vitro of organic extracts from fourteen seaweeds, eleven sponges, two ascidians, one bryozoan, and one sea anemone species collected along the Brazilian and Spanish coast, as well as the isolation of the diterpene (4R, 9S, 14S)-4α-acetoxy-9β,14α-dihydroxydolas

4. Detecção de Mycoplasma genitalium, M. fermentans e M. penetrans em pacientes com sintomas de uretrite e em indivíduos infectados pelo HIV-1 no Brasil
Neste trabalho investigamos a prevalência de três espécies de micoplasma recém-identificadas como patógenos humanos, M. genitalium, implicado em casos de uretrite não-gonocócica, e M. fermentans e M. penetrans, isolados de pacientes imunodeprimidos, e das duas espécies mais freqüentes no trato geniturinário, M. hominis e U. urealyticum. Foram estud

5. Development of artificial replicative plasmids for transformation of Mycoplasma pulmonis, M. capricolum and M. mycoïdes subsp. mycoïdes, and disruption of the M. pulmonis hemolysin A gene by homologous recombination / Desenvolvimento de plasmídeos replicativos artificiais para transformação de Mycoplasma pulmonis, M. capricolum e M. mycoïdes subsp. mycoïdes, e dirupção do gene da hemolisina A de M. pulmonis por recombinação homóloga
Mycoplasmas are the smallest microorganisms capable of self replication known to date, responsible for many diseases in man and animals, infecting also plants and insects. They constitute a large group of bacteria, classified in different genera in the class Mollicutes, which main common characteristic, besides the small genome, is the absence of a cell wall

6. Isolation and characterization of Mycoplasma genitalium strains from the human respiratory tract.
Mycoplasma genitalium, an organism first isolated from the urethras of two men with nongonococcal urethritis, has been found in throat specimens from military recruits participating in an inactivated Mycoplasma pneumoniae vaccine field trial in 1974-1975. Four of 16 preserved throat isolates, previously identified as strains of M. pneumoniae, have now been s

7. Quantitative Detection of Mycoplasma genitalium from First-Pass Urine of Men with Urethritis and Asymptomatic Men by Real-Time PCR
We developed a TaqMan-based real-time PCR assay for quantifying Mycoplasma genitalium. This assay is able to specifically quantify concentrations of the M. genitalium 16S rRNA gene ranging from 107 to 10 copies/reaction. Using the TaqMan assay, we quantified the M. genitalium 16S rRNA gene in first-pass urine of men with urethritis and asymptomatic men who w

8. Diagnostic Assessment of Mycoplasma genitalium in Culture-Positive Women
Detection of Mycoplasma genitalium-mediated, chlamydia-negative nongonococcal urethritis and other M. genitalium-linked infectious etiologies has been very challenging. Although M. genitalium is considered a leading cause of genitourinary symptoms in men and women, extreme difficulties in its cultivation due to its highly fastidious nature and the lack of ro

9. Longitudinal Quantitative Detection by Real-Time PCR of Mycoplasma genitalium in First-Pass Urine of Men with Recurrent Nongonococcal Urethritis
By using a TaqMan assay we monitored longitudinal changes in Mycoplasma genitalium loads in five men with recurrent M. genitalium-positive nongonococcal urethritis. We observed regrowth of M. genitalium persisting in hosts after treatment and a possible association of the increase in the M. genitalium load with emergence of symptoms and signs of nongonococca

10. Peptide Methionine Sulfoxide Reductase (MsrA) Is a Virulence Determinant in Mycoplasma genitalium
Mycoplasma genitalium is the smallest self-replicating microorganism and is implicated in human diseases, including urogenital and respiratory infections and arthritides. M. genitalium colonizes host cells primarily through adherence mechanisms mediated by a network of surface-associated membrane proteins, including adhesins and cytadherence-related proteins

11. DNA and protein sequence homologies between the adhesins of Mycoplasma genitalium and Mycoplasma pneumoniae.
Mycoplasma genitalium and Mycoplasma pneumoniae are morphologically and serologically related pathogens that colonize the human host. Their successful parasitism appears to be dependent on the product, an adhesin protein, of a gene that is carried by each of these mycoplasmas. Here we describe the cloning and determine the sequence of the structural gene for

12. Mycoplasma genitalium: a cause of male urethritis?
BACKGROUND--Male urethritis may be caused by mycoplasmas. Since Mycoplasma genitalium has previously been isolated from the urethra of two men with non-gonococcal urethritis (NGU), it was the aim of the study further to elucidate its role by measuring the prevalence of this organism in men with NGU. MATERIAL AND METHODS--The polymerase chain reaction was use
