Advances in serotypes of perinatal Group B Streptococcus infection / 中华围产医学杂志

ABSTRACT

Group B Streptococcus (GBS) is an important pathogen which may result in miscarriage, intrauterine infection and puerperal infection. Neonatal GBS infection may lead to septicemia, pneumonia and meningitis. GBS can be divided into a variety of serotypes according to the antigenic structure of capsular polysaccharide, and different serotypes of GBS vary in ethnicity, geographical distribution, pathogen virulence and pathogenic species. The distribution and identification of GBS serotypes, and their relationships with genotypes, drug resistance, virulence factors and vaccine preparation of GBS were reviewed.
