“…These findings indicate that the presence of mycoplasmas in semen does not associate with leukocytospermia, in spite of being potentially pathogenic species. They are consistent with previous reports [17][18][19].…”

Aim: To investigate the clinical value of the screening of Ureaplasma urealyticum and Mycoplasma hominis in routine semen analysis. Material and Methods: Semen samples of 234 patients with several clinical settings (infertility, varicocele, spontaneous abortion, genital infections, undescended testicles, hemospermia, etc.) were distributed in three study groups: group 1 -- negative cultures; group 2 – normal colonization (≤10³ colony-forming units (cfu)/ml), and group 3 – pathogenic colonization (>10³ cfu/ml). Frequency rates, incidence by age and clinical settings, association with abnormal sperm characteristics (density, vitality, motility and morphology) and with the leukocyte count were investigated. Results: Prevalence of U. urealyticum was higher than M. hominis (≤10³ cfu/ml: 28.2 vs. 24.8%; >10³ cfu/ml: 20.5 vs. 13.3%). No difference was detected on the incidence of mycoplasmas by age and clinical settings, as well as in regard to the mean values of sperm density, vitality, motility, oval-headed sperm and leukocyte count (p > 0.05). Conclusion: In spite of the high incidence of mycoplasmas, not enough information was available regarding the influence of these microorganisms on the sperm quality and their relationship with the leukocyte count. Therefore, screening of U. urealyticum and M. hominis for routine semen analysis is not clinically relevant.

“…Assessment of the pathogenic potential of M. horninis is complicated by a high degree of genomic and antigenic heterogeneity within the species. The picture is hrther complicated by the fact that the micro-organism is isolated frequently from asymptomatic males and females [7]. been studied by several approaches.…”

Sixty Mycoplasma horninis isolates were obtained from the cervices of pregnant women and from the ears or pharynges of their newborn babies. The isolates were examined by SDS-PAGE and pulsed-field gel electrophoresis. Antigenic and genomic profiles were obtained for 16 series with two or more successive isolates. Both analyses led to the conclusion that isolates from the same woman were identical or nearly identical, while isolates from different women exhibited a high degree of variation with respect to both genomic and antigenic profiles.

“…Certainly, the anatomical distribution of the chimpanzee ureaplasmas and mycoplasmas was simi¬ lar to that seen in humans, i.e. infrequent occurrence in the throat compared to that in the genital tract and a greater frequency in the female than in the male genital tract (Taylor-Robinson, 1986;Furr & Taylor-Robinson, 1987). This is quite different from that in marmosets in which urea¬ plasmas are found predominantly in the throat (Furr et al, 1976).…”

Adult chimpanzees (24 male, 76 female) with low and high rates of conception were examined for ureaplasmas, arginine-metabolizing mycoplasmas and chlamydiae. Ureaplasmas were isolated from the throat of only 1 male and 1 female animal, but from the urethra of 29% of the males and from the vagina of 95% of the females. Mycoplasmas were isolated from the throat more often than were ureaplasmas, but from the genital tract with about the same frequency as ureaplasmas. The numbers of organisms, of either type, isolated from the vagina were larger than the numbers isolated from the male urethra. Chlamydiae were not isolated from any animal. The occurrence of ureaplasmas and mycoplasmas and the numbers of these organisms isolated were similar in animals with low or high rates of conception. Furthermore, no association was noted between the organisms in the lower genital tract and the occurrence of abortion and/or stillbirth.
