GBS-EOD infections presented in infants whose mothers had been screened as GBS culture-negative are particularly worrying, and may be caused by incorrect sample collection, delay in processing the samples, incorrect laboratory techniques, recent antibiotic use, or GBS colonization after the screening was carried out.
A GBS vaccine is currently being tested but not currently available. Vaccination is estimated to being able to prevent 4% of GBS infections for preterm births and 60–70% for neonatal GBS infections in the US. The projected benefits of maternal vaccination is the prevention of 899 cases of GBS disease and 35 deaths among infants.
Streptococcus agalactiae (also known as group B streptococcus or GBS) is a gram-positive coccus (round bacterium) with a tendency to form chains (as reflected by the genus name Streptococcus). It is a beta-hemolytic, catalase-negative, and facultative anaerobe. [1] [2]
There are three purposes of prenatal diagnosis: (1) to enable timely medical or surgical treatment of a condition before or after birth, (2) to give the parents the chance to abort a fetus with the diagnosed condition, and (3) to give parents the chance to prepare psychologically, socially, financially, and medically for a baby with a health problem or disability, or for the likelihood of a ...
In the field of genetic sequencing, genotyping by sequencing, also called GBS, is a method to discover single nucleotide polymorphisms (SNP) in order to perform genotyping studies, such as genome-wide association studies . [1] GBS uses restriction enzymes to reduce genome complexity and genotype multiple DNA samples. [2]
Neonatal sepsis is a type of neonatal infection and specifically refers to the presence in a newborn baby of a bacterial blood stream infection (BSI) (such as meningitis, pneumonia, pyelonephritis, or gastroenteritis) in the setting of fever.
New research suggests that exposure to fluoride during pregnancy could be linked to behavioral issues in children.
This is an example of a positive CAMP test indicated by the formation of dark arrowheads where the Strep group B (Streptococcus agalactiae) meets the Staphylococcus aureus (light-yellow/golden middle streak with surrounding dark hemolysis).
