Abstract

Objective: Determine the rate of positive GBS and related factors in vaginal-rectal fluid samples in pregnant women 36 - 38 weeks at Saigon International Obstetrics Hospital. Methods: Cross-sectional study design surveyed 280 pregnant women with gestational age from 36 - 38 weeks at Saigon International Obstetrics Hospital, cultured and identified Streptococcus group B. Results: The rate of vaginal-rectal GBS infection in pregnant women 36 - 38 weeks at Saigon International Obstetrics Hospital is 12.3%. Factors related to the rate of GBS infection are pregnant woman's age (≥ 35) (OR 1.98, CI 1.14 - 3.45), history of vaginitis (OR 2.98, CI 1.09 – 8.14), clinical symptoms of vaginitis (OR 3.09, CI 1.41 – 6.76), pregnant women clean after urinating with water (OR: 2.32; CI: 1.07- 4.99), intercourse within 1 month before testing (OR 2.79, CI 1.14 - 6.83). Ampicillin, Penicillin, Cefepime, Ceftriaxone, Linezoid and Vancomycin are 100% sensitive. Tetracycline antibiotics 100% resistant; Erythromycin, Clarithromycin and Clindamycin had resistance rates of 42.9%, 39.3% and 35.7% respectively. Conclusion: It is necessary to increase screening for GBS in pregnant women aged 35 and older. A history of vaginitis and clinical symptoms of vaginitis are two risk factors that increase the possibility of GBS positivity in pregnant women that need attention.
