Objective: To investigate the microecology and common infection of the female vagina in border area of Chongzuo City. Methods: Female patients in the outpatient department and inpatient department of gynecology of our hospital from April 1, 2018 to August 23, 2021 were selected as the research objects. The reproductive tract secretions of all patients were examined by microecological examination, morphological examination, chemical analysis and microscopic examination, and the results of various indicators were statistically analyzed to draw relevant conclusions. Results: Among the 1498 women with vaginal micro- ecological imbalances, cleanliness was determined to be 534 cases of degree II, 868 cases of degree III, and 96 cases of degree IV; Nugent scores were 9 - 10 in 9 cases, 8 in 122 cases, 7 in 30 cases, 6 in 18 cases, 5 in 8 cases, 4 in 717 cases, 3 in 248 cases, 2 in 209 cases, 1 in 118 cases, and 0 in 19 cases. AV scores were 8 in 1 case, 7 in 1 case, 6 in 2 cases, 5 in 9 cases, 4 in 84 cases, 3 in 207 cases, 2 in 850 cases, 1 in 284 cases, and 0 in 60 cases. Among the pathogen infections, 99 cases were mycoplasma, 361 cases were candida, 199 cases were bacterial and 8 cases were trichomonas; In chemical analysis, there were 138 cases with pH 5.1, 326 cases with pH 4.8, 775 cases with pH 4.6, 217 cases with pH 4.4, and 42 cases with pH 4.1; meanwhile, 1390 cases were positive for hydrogen peroxide, 505 cases were positive for glucosidase, 487 cases were positive for acetylglucosaminidase, 184 cases were positive for sialidase, 290 cases were positive for proline amino-peptidase, 501 cases were positive for coagulase, and 1064 cases were positive for leukocyte esterase. Conclusion: Female reproductive tract microecology is more complex, and the pathogens of infection are also diverse. A systematic examination can clarify the occurrence and development of the disease, and then provide reliable laboratory data for clinical treatment and guide clinical medication.
