Rapid screening for Streptococcus agalactiae in vaginal specimens of pregnant women by fluorescent in situ hybridization.
نویسندگان
چکیده
Group B streptococci (GBS) are the most frequent pathogens in neonates with sepsis. A rapid screening method is required to identify carriage of GBS in pregnant women at the time of delivery. In order to detect GBS in vaginal specimens, the efficiency of the standard culture versus fluorescent in situ hybridization (FISH) was investigated. In 258 examined vaginal specimens, FISH identified 58 of the 59 GBS-positive samples (98.3%), whereas by means of standard culture only 38 specimens were positive (64.4%). We recommend FISH as a rapid, specific, highly sensitive screening technique for the detection of GBS in pregnant women at delivery.

BACKGROUND Pregnant women colonized by Streptococcus agalactiae (group B streptococci [GBS]) may transfer this microorganism to their newborns. S. agalactiae is an important cause of pneumonia, sepsis, and meningitis in newborns. Fluorescent in situ hybridization (FISH) is considered as a method of identification in the field of diagnostic microbiology. In this paper, we have designed a study t...

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...

Background and Aim: Group B streptococcus(GBS)(Streptococcus agalactiae) is the leading cause of morbidity and mortality of the newborn infant and accounted as a factor leading septicemia after birth in mothers. Infections in infants are usually acquired by contact with the genital tract of the mother during labor and delivery. So a rapid screening test for group B streptococcus that could accu...

Introduction: Group B Streptococcus (GBS) is one of the most causes of neonatal infections. The bacterium colonizes genitourinary tracts of pregnant women and transmits to infants. The aim of this study was investigating colony PCR and culture methods to detection of GBS in pregnant women. Materials and methods: Hundred pregnant women, at the 35th and 37th weeks of pregnancy, were selected fro...
