isolation and molecular identification of mycoplasma hominis in infertile female and male reproductive system

results among 100 samples from infertile males, the presence of genus mycoplasma was confirmed in 45 cases of which 15 cases were infected with m. hominis. among 100 samples from infertile female, the presence of genus mycoplasma was confirmed in 43 cases of which 18 case were infected with m. hominis. the positive samples were sequenced and the phylogenetic tree was plotted. conclusions the results showed that 37.5% of infertile males and females were infected with m. hominis. analysis of the nucleotide sequences of the study isolates indicates a particular variety among these isolates. in comparing the isolates in the study, a very little genotypic similarity was found among some of them. background infection of urogenital system with mycoplasma potentially affect reproductive system and increases infants mortalities. therefore, detection of these organisms is an important issue that should be considered and appropriate diagnostic methods should be used to identify these microorganisms. in the female reproductive system, infection can affect different parts of the cervix, endometrium, and fallopian tube. the extent of this infection in different diseases and its pathogenesis might be related to anatomic site of involvement. some infections can lead to infertility in both males and females. genital infection with mycoplasmas have devastating effects on reproductive organs and cause fertility disorders and mortality in infants. in recent years, many studies have been conducted to isolate these pathogens; however, the isolates have not been identified so far. objectives the aim of this study was to determine the molecular identity of mycoplasma hominis isolated from infertile female and male reproductive system in the infertility center of kerman. materials and methods this descriptive study was performed purposefully on 100 infertile females and 100 infertile males who were referred to the infertility center of kerman during a six-month period. the collected samples of semen and vaginal swabs were examined for the presence of m. hominis by pcr. the samples with positive results in pcr were selected for molecular identification. alignment of samples sequence was performed using mega 5 software through neighbor-joining method.
