Urogenital Mycoplasma Infection and Antibiotic Susceptibility

OBJECTIVE To investigate urogenital mycoplasma infection and its drug sensitivity in Beijing from Jul 2002 to Jun 2005. METHODS Mycoplasma were isolated and their antibiotic susceptibility was detected with Mycoplasma IST 2 Reagent Box from France. RESULTS Among 1806 cases 673 cases were with positive mycoplasma,accounting for 37.3% of the total.From them,Ureaplasma urealyticum(Uu) was positive in 541 cases(80.4%),higher than Uu combined with Mycoplasma hominis(Mh) infection(107 cases,15.9%) or Mh alone infection(25 cases,3.7%).The result of drug sensitivity test showed that Uu,Mh and Uu+Mh isolated from both sexes had different drug resistance.The most sensitive and stable antibiotics were josamycin(the rate of sensitivity was 98.7%) and pristinamycin(the rate of sensitivity 92.6%),the next was doxycyline(the rate of sensitivity was 91.8%).It seemed increasing sensitivity trend for tetracycline and erythromycin.The lowest rate of sensitivity was to ofloxacin and ciprofloxacin. CONCLUSIONS It is important to enhance the detection of drug resistance of mycoplasma,guide the drug use and prevent from producing antibiotic resistance.If antibiotic susceptibility testing of mycoplasma can not be tested,josamycin may be selected as the first choice to treat mycoplasma infection.
