Among 726 cases, E. coli were Identified in 98 cases, 13.4%. 2. The rate of detecting E. coli was 10.3% in the pregnant group and 21.6/ in the patient group. When classified by regions on all patients, 11.8% at the external genitalia, 5.2/ at the posterior vault of the vagina, and 4.4% were detected at both regions at the same time. 3. As regards the relation between the detecting E. coli and period of pregnancy, detecting rate was high at the early stage and post delivery. 4. The value of pH in the vagina was 4.7ln average in the pregnants, and among them 4.9 in average E. coli positive cases, It was 5.3 in average in the patients, and 5.4 in average in the E. coli positive cases. 5. When the rate of decting E. coli is classified by the disease, it was relatively high in simple vaginitis, symptomless, erosion of the uterine neck, irregular hemorrhage, leukorrhea and so on. 6. Examining E. coil relatively often detected by O-type serum classification, on E. coil in the genital organ, type O-8 was most abundant and followed by in order of O-7, O-23, O-1, O-16, O-2, O-17. In E. coil in the feces, type O-7 is most abundant, followed by in order of O-8, O-16, O-2, O-17. 7. The cases in which E. coil in the genital organs and in the feces coincided in serological classification were 37.7%, 31.5% in the pregnat group and 45.5% in the patient group. 8. As for the degree of sanitary distribution, in the pregrant group, the sanitary degree I° was 12.9%, II° 55.5% and III° 31.4%, and in the patient group, I° was 13.6%, II° 36.3%, and III° 50%. And in general, the lower the sanitary degree, the higher the rate of detecting E. coli.
