  • Mycoplasma hominis causes genital mycoplasmal infections, which may result in diverse manifestations. (medscape.com)
  • They (and Mycoplasma hominis ) are often present in patients with other urogenital infections (eg, vaginitis, cervicitis, pyelonephritis, pelvic inflammatory disease) and some nonurogenital infections, but their role in these infections is not clear. (msdmanuals.com)
  • Clinical manifestations range from mild cases of tracheobronchitis to severe atypical pneumonia and can be followed by a broad spectrum of extrapulmonary complications. (cdc.gov)

  • Mycoplasmas are ubiquitous bacteria that differ from other prokaryotes in that they lack a cell wall. (msdmanuals.com)
  • Patient education regarding the common occurrence, relatively mild nature, appropriate therapy, and usually complete recovery from Mycoplasma infection is important. (medscape.com)
  • Mycoplasma organisms cause infection primarily as extracellular parasites, attaching to the surface of ciliated and nonciliated epithelial cells of the respiratory and genital tracts. (medscape.com)
  • All mycoplasmas lack a cell wall and, therefore, all are inherently resistant to beta-lactam antibiotics (e.g., penicillin). (cdc.gov)
  • Because mycoplasmas, which do not have cell walls, are not susceptible to β-lactam antimicrobial drugs, macrolides are generally accepted as first-choice agents for treatment, especially in children. (cdc.gov)
