BACKGROUND: Group B Streptococcus (GBS) infection is one of the major causes of neonatal morbidity and mortality. Universal GBS screening with intrapartum antibiotic prophylaxis (IAP) in pregnant women were initiated in 2012 in Taiwan. This study aimed to analyze the most recent maternal GBS colonization rate and the changes in neonatal GBS infection rate from 2011 to 2016. METHODS: All pregnant women and their live born neonates between January 2011 and June 2016 were retrospectively reviewed...

This pilot study assessed the diagnostic accuracy and potential impact of a rapid PCR-based screening test for the detection of group B Streptococcus (GBS) at the onset of labour for the purpose of optimising intrapartum antibiotic prophylaxis (IAP). Vaginal and rectal swabs from a convenience sample of 158 women were analysed by conventional broth-enriched culture and a rapid PCR test. Overall, GBS carriage was 18.98% by culture and 19.62% by PCR. PCR for the detection of GBS had a sensitivity of 93.1%, specificity of 96...

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 culture (gold standard), in GBS colonization screening of pregnant women, and to establish the prevalence of GBS colonization among this population...

PTA is a collection of pus located between the tonsillar capsule and the pharyngeal constrictor muscle. It is considered a complication of acute tonsillitis and is the most prevalent deep neck infection (approximately 2000 cases annually in Denmark) and cause of acute admission to Danish ENT departments. Teenagers and young adults are most commonly affected and males may predominate over females. However, no studies of age- and gender-stratified incidence rates have previously been published. Furthermore, smoking may be associated with increased risk of peritonsillar abscess (PTA) development, although the magnitude of the association has not been estimated...

BACKGROUND: The current recommendation regarding the management of a term newborn delivered of a mother with an intrapartum fever or a diagnosis of clinical chorioamnionitis is that the neonate should have baseline laboratory work drawn along with blood cultures and be universally treated with antibiotics until culture results return. These guidelines report that the rate of intrapartum fever is about 3%; however, a few large studies suggest that the rate is higher at about 7%. OBJECTIVE: We sought to prospectively evaluate the rate of fever during labor in a large number of deliveries and determine the rate of early-onset neonatal sepsis in newborns delivered from mothers with an intrapartum fever compared with newborns delivered from mothers without intrapartum fever...

BACKGROUND: Infections by group B streptococci (GBS), e.g. Streptococcus agalactiae, presenting as early-onset disease (EOD) or late-onset disease (LOD), are leading causes of severe infections in newborn and premature patients. Although screening and intra partum antibiotic prophylaxis are frequently performed, vertically transmitted GBS remain a challenge for pediatrics. AIMS: In order to prevent or reduce potential life-threatening events, this study retrospectively investigated epidemiological, microbiological and clinical aspects of infants admitted to the Division of Neonatology at the Department of Pediatrics at the University Hospital Frankfurt, Germany (UHF)...

INTRODUCTION: Group B streptococcus (GBS) is the most common infectious agent responsible for early-onset bacterial sepsis (EOS) in term newborns. French prevention of perinatal GBS disease guidelines recommend screening for maternal vaginal GBS colonization at the 9th month of pregnancy, and use of intrapartum antibiotic prophylaxis (IAP) in case of detected GBS vaginal colonization. Peripheral bacterial sampling (gastric aspiration, ear, or meconium) and measurement of C-reactive protein (CRP) are performed in asymptomatic newborns in case of infectious risk factors and/or incomplete IAP...

Group B Streptococci (GBS) are ß-hemolytic, gram-positive bacteria that are typically associated with infections in human newborns or immunocompromised adults. However, mutation in the two-component regulator CovR/S relieves repression of hemolysin, potentially increasing virulence of GBS. We report the isolation of hyperhemolytic/hyperpigmented GBS strain from an adolescent patient who presented to the University of Washington clinic with symptoms of sore throat. While the patient also tested positive for mononucleosis, a GBS strain with increased hemolysis was isolated from the throat swab obtained from the patient...

AIMS: Group B streptococcal (GBS) disease is the leading cause of early-onset neonatal sepsis in New Zealand. Disease follows vertical transmission of GBS from the mother, which can largely be prevented by intravenous intrapartum antibiotics. A 2004 New Zealand guideline recommended using clinical risk factors to identify mothers who would qualify for intrapartum antibiotics. An expert multidisciplinary group met to reconsider these guidelines in the light of a two year survey of the incidence of early onset GBS neonatal sepsis...

Early onset sepsis (EOS) is a worrisome, life-threatening condition in newborns with onset during the first week of life. Evaluation can be challenging due to the dynamic nature of the condition as the infant transitions to life ex-utero. Symptoms/signs can be nonspecific, thus, a high index of suspicion is warranted for subtle changes in condition including poor feeding, respiratory distress, or decreased activity. Common risk factors include chorioamnionitis, maternal fever, group B strep (GBS) colonization and preterm delivery...

BACKGROUND & OBJECTIVES: One of the important infectious factors in pregnant mothers and newborns is Group B Streptococcus (GBS). There is no perfect report about prevalence of GBS in Iran and in the case of preterm rupture of amniotic membrane or preterm labor all patients are treated by antibiotics without culture so this has led to adverse taking antibiotics and drug resistance. The present study is intended to determine the frequency of colonization of GBS in the pregnant mother (35-37 weeks), referred to medical centers of Shahed University...

INTRODUCTION: Early-onset neonatal infection remains a major cause of morbidity and mortality in neonates. Both universal vaginal screening for group-B streptococcus (GBS) and intrapartum antibiotic prophylaxis have decreased the incidence of early-onset GBS disease. Almost 12 years after the implementation of the French recommendations, we assessed the practices around screening, diagnosis, and treatment of early-onset neonatal infection in the Île-de-France region. PATIENTS AND METHODS: We conducted a prospective, multicenter, observational study in 14 volunteer maternity wards from 18 to 31 March 2013...

Universal screening for maternal group B Streptococcus (GBS) in the prenatal period has led to administration of intrapartum antibiotic prophylaxis (IAP). Although IAP decreased the rate of early neonatal GBS disease, exposure of childbearing women to penicillin and other beta-lactam antibiotics has increased. Beta-lactam-induced anaphylaxis in the breastfeeding woman during the postpartum period illustrates risk factors for beta-lactam allergy and anaphylaxis. Treatment and nursing implications for this adverse reaction are suggested...
