[Pathogenic bacterium and drug resistance in cervical cancer patients complicated with reproductive tract infection].
OBJECTIVE
To determine the vaginal flora distribution in cervical cancer patients and the common pathogenic bacteria as well as drug resistance, and to explore the correlation of vaginal bacterial infection and high-risk human papillomavirus (HR-HPV) infection with cervical cancer.


METHODS
A total of 216 patients with cervical cancer served as an experimental group, and 53 patients with chronic cervicitis served as a control group. The patients' vaginal fluid in two groups was collected before the treatment for regular bacterial culture and HPV testing. The distribution and drug resistance of bacteria in two groups of vaginal secretion were observed, and the correlation of the bacterial infection and HPV infection with the cervical cancer was analyzed.


RESULTS
The gram-negative and gram-positive bacteria accounted for 74.38% and 21.49% in the experimental group, respectively. They were mainly resistant to ampicillin and piperacillin or penicillin and erythromycin. The gram-negative and gram-positive bacteria accounted for 42.31% and 23.08% in the control group, respectively. They were mainly resistant to ampicillin and piperacillin or penicillin. HPV-positive rates in the experiment group and the control group were 60.65% and 41.51%, respectively. There were 70 patients (32.41%) and 12 patients (22.64%) with both bacterial infection and HPV-positive infection in the experiment group and the control group, respectively. However, there was no statistical difference between the 2 groups (P>0.05).


CONCLUSIONS
Escherichia coli are the main pathogen in cervical cancer and they are highly resistant to antibiotics. Bacterial infection in genital tract is not an efficient cofactor for HPV to cause the cervical cancer.
