A genus of microaerophilic to anaerobic, nonmotile bacteria (family Mycoplasmataceae) with no cell walls. Gram-negative, they are predominantly coccoidal to coccobacillary elements, approximately 0.3 mcm in diameter, which frequently grow in short filaments; colonies are generally small, 20-30 mcm...
Mycoplasmas are small bacteria that lack a cell wall and are the smallest free-living organism. The lack of a cell wall imparts resistance to antimicrobials such as the beta-lactams, which target the cell wall for activity. Mycoplasma salivarium can be isolated from marmosets as part of the...
No significant association was observed between week of delivery of carrier women and newborn infection type (p = 0.18). In the current work, it was found that among women positive for the bacteria, 25% of the deliveries were preterm (before week 37), 2 (10.5%) were performed with ...
Ureaplasma urealyticum and Ureaplasma parvum are members of the Mycoplasmacetae family, which comprises some of the smallest, simplest microorganisms. With their small genomes and lack of a cell wall, these bacteria rely on the host organism for vital nutrients and have limited viability outside of...
Infection stones, composed of magnesium ammonium phosphate (struvite) and/or calcium phosphate are the second most common type of stone in the urinary tract in man (1). Urinary tract infection with urease-producing bacteria is considered a pre-requisite for the formation of these stones (2). ...
The increase in gelatinase activity from the amniotic fluid, but not from the Ureaplasma spp., strongly suggests a novel bacteria–host inter- action whereby Ureaplasma spp. might induce the release of MMP-9 from host neutrophils and critical interplay of Ureaplasma regulating host protease release....
molecular-based detection is the only practical means for microbiological diagnosis. Most molecular-based methods used for detection and characterization of conventional bacteria have now been applied to these organisms and some methods seem to work better than others. A complete genome sequence is now...
Ureaplasma urealyticum (UUR) and Ureaplasma parvum (UPA) are sexually transmitted bacteria among humans implicated in a variety of disease states including but not limited to: nongonococcal urethritis, infertility, adverse pregnancy outcomes, chorioamnionitis, and bronchopulmonary dysplasia in neonates...
Ureaplasma lung infection is associated with increased polymorphonuclear leukocytes in tracheal aspirates and focal loss of ciliated epithelium (5,6) and is more likely to progress to dysplastic changes and chronic lung disease com- pared with pneumonia attributed to other bacteria (4). Received ...
