The vaginal micro-flora of aerobic vaginitis and bacterial vaginosis.

Objective To analyze and evaluate the vaginal micro-flora in bacterial vaginitis(BV),aerobic vaginitis(AV) and normal female.Method Microbiological and biochemical methods of gram staining,selective culturing and isolating and pre-enzymes profile analysis were used.Result The normal vaginal flora was predominated by lactobacilli,89% of which were detected as producing H2O2.The pathogenic bacteria of AV was primarily Gram-positive aerobic bacteria,with the detection rate of 80% including Staphylococci aueas,Enterococcus faecalis and E.coli;low rate of B.streptococcic was detected.The pathogenic bacteria of BV was primarily Gram-negative anaerobic bacteria,while the rate of Gardnerella was detected as less than 40%.There were 8 cases with of AV concurrent infection in 48 cases of BV infection,and 6 cases with BV concurrent infection in 31 cases of AV infection.Conclusion Microphyte profile analysis indicated that patients infected by AV were susceptible to anaerobic bacteria such as Gardnerella,Prevost bacteria and Peptostreptococcus,while patients infected BV were susceptible to aerobic bacteria such as Enterococcus faecalis and E.coli etc.
