Expression of circulating white blood cells was investigated in rats (Rattus norvegicus) experimentally infected with larvae of Dermatobia hominis, the human bot fly. Leucocytes were counted prior to infection (control group) as well as at 6, 10, 15, 20 and 28 days post-infection (dpi) and at 7, 15, 30 and 60 days post-larval emergence (dple). Total leucocyte numbers did not differ markedly amo...

Organ cultures of human Fallopian tubes were infected with Mycoplasma hominis. Scanning and transmission electron microscopy revealed swelling of the cilia of the tubal epithelial cells in infected cultures. In some, the entire cilia were swollen; in others, only the tips. Uninfected cultures kept for up to 7 days showed no structural changes in the cilia or other surface structures. M. hominis...

Ureaplasma urealyticum (UU) and Mycoplasma hominis (MH) have been detected in the urine of women with systemic lupus erythematosus (SLE). We evaluated the presence of these mycoplasma in the endocervix of women presenting SLE. A total of 40 SLE patients (mean age 40.2 years), and 51 healthy women (mean age 30.9 years), were studied. Endocervical swabs were cultured in specific liquid media for ...

The genital mycoplasmas, Mycoplasma hominis and Ureaplasma urealyticum eT-mycoplasmas) are common vaginal organisms. They are acquired primarily through sexual contact. There is evidence, some of it highly suggestive, linking the genital mycoplasmas to involuntary infertility, spontaneous abortion and low birth weight. Additional controlled treatment studies are needed in each of these areas to...

BACKGROUND Genital ureaplasmas (Ureaplasma urealyticum and Ureaplasma parvum) and mycoplasmas (Mycoplasma genitalium and Mycoplasma hominis) are potentially pathogenic species playing an etiologic role in both genital infections and male infertility. Reports are, however, controversial regarding the effects of these microorganisms infections in the sperm seminological variables. This study aime...

Contour clamped homogeneous field (CHEF) agarose gel electrophoresis (AGE), ramped to give linear separation of DNA molecules of 600-1600 kilobase pairs (kbp), was used to determine mobilities for full-sized genomic DNA of the serotype standard strains of the human genital mollicutes, Ureaplasma urealyticum relative to yeast chromosomal DNA markers. Indicated genome sizes (in kbp) were 760 for ...

The human spermatozoa! motility was significantly affected by the whole culture solution and slightly less significantly by the microbial cell suspension of Ureaplasma urealyticum but not the microbial metabolites (culture supernatant). The same phenomenon was observed with the preparations of Mycoplasma hominis in somewhat less degree.
