Levofloxacin and ofloxacin had MIC50S of1 μg/ml and 2 μg/ml, respectively against both species.Norfloxacin was less effective against both species at16 and 32 μg/ml. Ciprofloxacin was unusual in thatthe MIC50S varied fourfold between species, with 2 μg/ml against M. hominis and 8 μg/ml against U.urealyticum.Conclusions: The results can provide useful infor-mation for selecting fluoroquinolones for treatmentof urogenital mycoplasma infections.展开更多
Ureaplasma Urealyticum(UU) can not only cause a wide range of nongonococcalinfectionsto urogenital tract,but also lead to infertility,sterility,intrauterinefetal infection,abortion or other bad consequences.For males,...Ureaplasma Urealyticum(UU) can not only cause a wide range of nongonococcalinfectionsto urogenital tract,but also lead to infertility,sterility,intrauterinefetal infection,abortion or other bad consequences.For males,UU may cause prostatitis,epididymitis and other diseases.With great harm to the human health,UU infection has been taken as one of the most important STDs in China for prevention and cure.However,the drug resistance of UU is increasingly stronger with the widespread use of antibiotics.Many nongonococcal patients with mycoplasma infection often fail to be cured after a long time of treatment,and drug sensitive tests find that,multidrug resistance brings physical and mental pains to patients all the time.Luckily,integrated Chinese traditional and western medicine greatly improves the cure rate,though the mechanism is not clear.There have been many studies on the reversion action and mechanism of TCM on the antibiotic resistance of bacteria,but studies on the reversion to UU drug resistance are deficient.Here we chose some voluntary patients with multidrug resistance as the research objects,who received treatment in my hospital in recent 3 years.They were given the oral administration of self-prescribed Cangbai Shiduqing Granule.Then,Cangbai Shiduqing Granule's reversion effect on UU drug resistance,namely,the sensitivity transformation situation of drug-resistant antibiotics,was observed.And the observation results are presented in the paper.展开更多
