- to compare colonization of group b streptococcus (gbs) in diabetic and non-diabetic pregnant women. in this prospective study 50 pregnant women with diabetes mellitus (both pregestational and gestational) and 43 pregnant women without diabetes between 33 and 37 weeks' gestation were evaluated. three samples for group b streptococcal culture detection were obtained from each subject in the fol...

background: group b streptococcus is regarded as a potential factor for adverse outcomes of pregnancy such as preterm birth. objective: to study the association of maternal vaginal colonization with group b streptococcus (gbs) and preterm labor. materials and methods: from april 2005 to may 2006, vaginal culture for gbs were conducted in 101 laboring women with a gestational age of 24-37 weeks ...

Four studies assessed the frequency of vaginal Staphylococcus aureus colonization in healthy women and associated risk factors. An association was found between S. aureus vaginal colonization and colonization at the labia minora and the anterior nares. Significant risk factors associated with an increased risk of vaginal S. aureus in at least one study were a history of genital herpes simplex i...

While many virulence factors promoting Streptococcus pyogenes invasive disease have been described, specific streptococcal factors and host properties influencing asymptomatic mucosal carriage remain uncertain. To address the need for a refined model of prolonged S. pyogenes asymptomatic mucosal colonization, we have adapted a preestrogenized murine vaginal colonization model for S. pyogenes. I...

Acquisition and loss rates and estimates of duration of oral and vaginal Candida species colonization and candidiasis were examined among 868 human immunodeficiency virus (HIV)-seropositive and 437 at-risk HIV-seronegative women monitored prospectively during 1993-1999. Colonization and candidiasis acquisition rates, both oral and vaginal, were significantly higher among HIV-seropositive women;...

OBJECTIVE The genital mycoplasmas, Ureaplasma urealyticum and Mycoplasma hominis, are commonly identified in the vagina of healthy pregnant women. However, these microorganisms are the most common isolates from the amniotic fluids of women in preterm labor. The mechanisms responsible for vaginal colonization and ascent to the uterus remain undetermined. We evaluated the association between U. u...

Streptococcus agalactiae (group B streptococcus [GBS]) is a Gram-positive bacterium found in the female rectovaginal tract and is capable of producing severe disease in susceptible hosts, including newborns and pregnant women. The vaginal tract is considered a major reservoir for GBS, and maternal vaginal colonization poses a significant risk to the newborn; however, little is known about the s...

Objective The aim of this study was to investigate the prevalence of abnormal vaginal microorganisms in pregnant women according to trimester, and to determine whether the presence of abnormal vaginal colonization is associated with higher risk of miscarriage or preterm delivery. Furthermore, we analyzed delivery outcomes according to individual microorganism species. Methods We included preg...

BACKGROUND Maternal recto-vaginal colonization with Group B Streptococcus (GBS) and consequent vertical transmission to the newborn predisposes neonates to early-onset invasive GBS disease. This study aimed to determine the acquisition and loss of serotype-specific recto-vaginal GBS colonization from 20-37+ weeks of gestational age. METHODS Vaginal and rectal swabs were collected from HIV-uni...
