“…In addition, the interesting observation has been made that M. hominis and U. urealyticum have a tendency to occur together in patients with NGU. In one study 23 , ureaplasmas were isolated about twice as frequently from patients infected with M. hominis than from those not infected with this microorganism. Furthermore, M. hominis was also isolated more often from ureaplasma-positive than from ureaplasma-negative patients.…”

The prevalence of 3 mycoplasmas (Mycoplasma hominis, Ureaplasma urealyticum and Mycoplasma genitalium) was determined in a cohort of women with or without bacterial vaginosis (BV) and in their respective male partners. Heterosexual women with or without BV and their male partners were recruited and genital sampling for these microorganisms was performed. Seventeen women with BV and 21 women with normal flora, and their respective male partners, were recruited. M. hominis was present in 9 (53%) of 17 women with BV compared with none of 21 women without BV (P=0.0001). Of the 17 male partners of women with BV, 8 (47%) had M. hominis compared to 5 (24%) of 21 male partners of women without BV (not significant [n/s]). U. urealyticum was detected in 11 (65%) of 17 women with BV in comparison with 10 (48%) of 21 women without BV (n/s). U. urealyticum was present in 4 (24%) of 17 male partners of women with BV compared to 6 (29%) of 21 male partners of women without BV (n/s). M. genitalium was not detected in any of 15 women with BV and in only 2 (12%) of 17 women without BV (n/s). M. genitalium was present in 4 (25%) male partners of 16 women with BV in comparison with 3 (16%) male partners of 19 women without BV (n/s). Thus, M. hominis was the only mycoplasma detected significantly more often in women with, rather than in those without, BV. None of the mycoplasmas was found significantly more often in male partners of women with, rather than those without, BV. Overall, M. genitalium behaved somewhat similar to Chlamydia trachomatis. It was the least commonly occurring mycoplasma, a reflection perhaps of the relatively low incidence of partner change in this study population.

“…fermentans can be detected in the upper and lower urogenital and respiratory tracts and bone marrow, and has been associated with a variety of systemic conditions in adults including inflammatory arthritis and pneumonia (8,10,12,94,178,251,281,299,311). M. fermentans has not been shown to have a pathogenic role in male urethritis (72,287,297). It has been recovered from the throats of 16% of children with community-acquired pneumonia, some of whom had no other etiologic agent identified, but the frequency of its occurrence in healthy children is not known (281).…”

Mycoplasmas and Ureaplasmas as Neonatal Pathogens

SUMMARY The genital mycoplasmas represent a complex and unique group of microorganisms that have been associated with a wide array of infectious diseases in adults and infants. The lack of conclusive knowledge regarding the pathogenic potential of Mycoplasma and Ureaplasma spp. in many conditions is due to a general unfamiliarity of physicians and microbiology laboratories with their fastidious growth requirements, leading to difficulty in their detection; their high prevalence in healthy persons; the poor design of research studies attempting to base association with disease on the mere presence of the organisms in the lower urogenital tract; the failure to consider multifactorial aspects of diseases; and considering these genital mycoplasmas only as a last resort. The situation is now changing because of a greater appreciation of the genital mycoplasmas as perinatal pathogens and improvements in laboratory detection, particularly with regard to the development of powerful molecular nucleic acid amplification tests. This review summarizes the epidemiology of genital mycoplasmas as causes of neonatal infections and premature birth; evidence linking ureaplasmas with bronchopulmonary dysplasia; recent changes in the taxonomy of the genus Ureaplasma; the neonatal host response to mycoplasma and ureaplasma infections; advances in laboratory detection, including molecular methods; and therapeutic considerations for treatment of systemic diseases.

“…About 30-70% of male clinic patients suffer from NGU,6' and 20-30% of male patients treated for gonorrhoea with penicillin may subsequently need treatment for postgonococcal urethritis.5 Organisms commonly associated with NGU are C trachomatis and U urealyticum,9 10 and Haemophilus parainfluenzae was recently described as a possible causative agent. "I Franciosi et al12 demonstrated streptococci with the same serogroup B serotype in 45% of the male partners of women infected vaginally with group B streptococci.…”
