  • The Mycoplasma hominis vaa gene encodes a highly variable, surface antigen involved in the adhesion to host cells. (biomedcentral.com)
  • Mycoplasma hominis has certain adherence antigenic molecules which help it in cytoadherence. (askmicrobiology.com)
  • As a consequence of the direct exposure of proteins located on the surface of the cytoplasmic membrane to the surrounding environment, antigenic variation of surface proteins is observed among mycoplasmas. (biomedcentral.com)
  • Any assessment of the pathogenic potential of M. hominis is complicated by the high degree of genomic and antigenic heterogeneity observed within the species. (beds.ac.uk)
  • This is mainly because many healthy adults have genitourinary colonization with Mycoplasma, published studies on pathogenicity have important design limitations and the organisms are very difficult to detect. (wikipedia.org)
  • In humans, mycoplasmas colonize mainly the upper respiratory tract and the genitourinary tract. (biomedcentral.com)
  • While infectious peritonitis is a common occurrence in patients with liver cirrhosis, Mycoplasma is rarely identified as a causative agent. (biomedcentral.com)
  • The occurrence of M. hominis organisms in a large number in the vagina and cervix is recognized as being associated strongly with BV. (beds.ac.uk)
  • Mapping of vaa on existing physical maps of five M. hominis isolates by pulsed field gel electrophoresis revealed that vaa is located in a genomic region containing the majority of other characterized membrane protein genes of M. hominis . (biomedcentral.com)
  • Doxycycline, minocycline, josamycin, and sparfloxacin can be recommended for first-line empirical treatment of Mycoplasma infections in infertile men in Shanghai, China. (springer.com)
  • Eighty-three patient cervical swab samples from infertile women were cultured for M. hominis in the BEa medium. (biomedcentral.com)
  • M. hominis uses an atypical type of energy metabolism, dependent upon the degradation of arginine. (wikipedia.org)
  • The molecular basis for antigen variation of M. hominis surface proteins has been elucidated in some cases. (biomedcentral.com)
  • The described PCR assay has replaced conventional culture for M hominis at Mayo Medical Laboratories due to its speed and equivalent performance to culture. (marshfieldlabs.org)
  • Sequencing of an 11 kb region containing the vaa locus of M. hominis isolate 132 showed the presence of conserved housekeeping genes at the borders of the region, uvrA upstream and the hitABL operon downstream to vaa . (biomedcentral.com)
  • Lactobacilli, Gardnerella vaginalis , and Mycoplasma hominis in cervicovaginal lavage samples were quantified by PCR. (pubmedcentralcanada.ca)
  • Increasing levels of G. vaginalis and M. hominis and decreasing levels of lactobacilli were significantly associated with BV by Nugent score. (pubmedcentralcanada.ca)
  • Of the group with Nugent scores of 7 to 10, 83% and 81% had log 10 G. vaginalis counts and log 10 M. hominis counts greater than 6.81 and 4.82, respectively, while only 30% and 31% of the group with Nugent scores of 0 to 3 were above these thresholds, respectively. (pubmedcentralcanada.ca)
  • PCR quantification of G. vaginalis and M. hominis from CVL is significantly more sensitive than Amsel criteria for diagnosing BV. (pubmedcentralcanada.ca)
