evaluation of culture and pcr methods for diagnosis of group b streptococcus carriage in iranian pregnant women

Evaluation of Culture and PCR Methods for Diagnosis of Group B Streptococcus Carriage in Iranian Pregnant Women

BACKGROUND Group B streptococcus (GBS) is one of the most important cause of morbidity and mortality among newborns especially in developing countries. It has been shown that the screening approach rather than the identification of maternal clinical risk factors for early-onset neonatal GBS disease is more effective in preventing early-onset GBS neonatal disease. The objective of this study was...

Group B Streptococcus detection in pregnant women via culture and PCR methods.

INTRODUCTION: Group B Streptococcus (GBS), a source of neonatal infection, colonizes the gastrointestinal and genitourinary tracts of pregnant women. Routine screening for maternal GBS in late pregnancy and consequent intrapartum antibiotic prophylaxis have reduced the incidence of early-onset GBS neonatal infection. The aim of this study was to evaluate the performance of PCR, compared to cult...

Comparison of different sampling techniques and of different culture methods for detection of group B streptococcus carriage in pregnant women

BACKGROUND Streptococcus agalactiae (group B streptococcus; GBS) is a significant cause of perinatal and neonatal infections worldwide. To detect GBS colonization in pregnant women, the CDC recommends isolation of the bacterium from vaginal and anorectal swab samples by growth in a selective enrichment medium, such as Lim broth (Todd-Hewitt broth supplemented with selective antibiotics), follow...

The Prevalence of Group B Streptococcus Colonization in Iranian Pregnant Women and Its Subsequent Outcome

Prevalence of positive recto-vaginal culture for Group B streptococcus in pregnant women at 35-37 weeks of gestation

 Background: Recto-vaginal colonization of Group B streptococcus (GBS) has been known as an important issue in mother and newborn’s health, which is getting frequent in developing countries. Screening test have been introduced and utilized in many countries and is recommended by many researchers. However, due to lack of information in prevalence of GBS, especially in Iran, there are doubts and ...

Comparative Molecular and Microbiologic Diagnosis of Vaginal Colonization by Group B Streptococcus in Pregnant Women during Labor

Objective(s) Rapid tests for detection of Streptococcus agalactiae or Group B Streptococci (GBS) at the onset of labor are needed to permit early intrapartum antibiotic prophylaxis. This study aimed to evaluate the PCR assays targeting the 16S ribosomal RNA gene (16S rDNA) for detection of the GBS in comparison with a specific culture method. Materials and Methods Two swabs were used to obta...
