Molecular design of Mycoplasma hominis Vaa adhesin

Molecular basis of size and antigenic variation of a Mycoplasma hominis adhesin encoded by divergent vaa genes.

The molecular basis for the size and antigenic diversity of the variable adherence-associated (Vaa) antigen, a major surface protein and a putative adhesin (of Mycoplasma hominis, is described. Size-variant alleles of the single-copy vaa gene encode abundant surface lipoproteins containing one to four nearly identical, tandem repetitive units of 121 amino acids in the central region of the matu...

Characteristics of Mycoplasma Hominis

Ultrastructure of Mycoplasma hominis.

Anderson, Douglas R. (National Cancer Institute, Bethesda, Md.), and Michael F. Barile. Ultrastructure of Mycoplasma hominis. J. Bacteriol. 90:180-192. 1965.-Both thin-sectioning and negative staining were used in an electron microscopic study of the morphology of pleuropneumonia-like organism (PPLO) strain HEp-2 (Mycoplasma hominis, type I) grown in an artificial liquid medium. The morphology ...

Molecular mechanism of fluoroquinolones resistance in Mycoplasma hominis clinical isolates

To evaluate the molecular mechanism of fluoroquinolones resistance in Mycoplasma hominis (MH) clinical strains isolated from urogenital specimens. 15 MH clinical isolates with different phenotypes of resistance to fluoroquinolones antibiotics were screened for mutations in the quinolone resistance-determining regions (QRDRs) of DNA gyrase (gyrA and gyrB) and topoisomerase IV (parC and parE) in ...

Mycoplasma hominis in pregnancy.

One hundred and seventyone antenatal patients were examined for the presence of ;large colony' mycoplasmas in the vagina, and for complement-fixing antibody to Mycoplasma hominis. In 25 patients the findings before and after delivery were compared. In patients from whom M. hominis was grown, antibody was twice as common after delivery, and the development of antibody was sometimes associated wi...
