Abstract: To examine the interaction between genital mycoplasmas and other genital pathogens from the
vaginal tracts of women of reproductive age, 168 high vaginal swabs were studied microbiologically.
Sixty (35.7%) genital mycoplasmas were isolated along with a total of 76 (45.2%) other microorganisms.
Candida albicans, Gardnerella vaginalis and Escherichia coli had prevalence rates of 16.7%, 11.9% and 8.3%
respectively. Others are Staphylococcus aureus (3.6%), Trichomonas vaginalis (3.4%) and Beta haemolytic
Streptococcus (1.2%). B-haemolytic streptococci had the highest interaction rate (100%) with genital
mycoplasmas and was followed by T. vaginalis, G. vaginalis and C. albicans with 55.6%, 55% and 45.5%
interaction rates respectively. Others had significantly low interaction rates of 7.1% for Escherichia coli and
0.0% for Staphylococcus aureus. Apart from Gardnerella vaginalis the prevalence of vaginal microorganisms
were more from pregnant than non-pregnant women. Though the presence of all these organisms in the
urogenital tracts of these women was largely asymptomatic, they could play various adverse roles in the long
run.
