title: Internal bacterial flora of solid uterine cervical cancer.
abstract: Twenty-five patients with uterine cervical cancer (Two cases stage O; four cases stage Ia; five cases stage Ib; one case stage IIa; ten cases stage IIb; two cases stage IIIa; one case stage IVa) served as the subjects. The bacterial flora inside the cervical cancers was investigated using the optimal technique. There was mixed abnormal aerobic and anaerobic bacterial flora in all subjects. The average number of bacterial species isolated from inside the cervical cancers was 6.3. The predominant bacteria isolated were the aerobes, Staphylococcus haemolyticus, Streptococcus agalactiae, Escherichia coli and Gardnerella vaginalis, and Prevotella bivia. As the stages of cervical cancer progressed, G. vaginalis, B. distasonis and P. bivia were detected at higher rates and higher counts than other bacteria. These findings suggest that there is a relationship between G. vaginalis, B. distasonis and P. bivia and the onset and growth of cervical cancer.
