Colonization with GBS during labor is the primary risk factor for the development of GBS-EOD. GBS-EOD is acquired vertically (vertical transmission), through exposure of the fetus or the baby to GBS from the vagina of a colonized woman, either in utero (because of ascending infection) or during birth, after rupture of membranes. Infants can ...
A temperature rise above 38 °C (100.4 °F) maintained over 24 hours or recurring during the period from the end of the first to the end of the 10th day after childbirth or abortion. (ICD-10) Oral temperature of 38 °C (100.4 °F) or more on any two of the first ten days postpartum.
Importantly, Streptococcus agalactiae is the most common cause of meningitis in infants from one month to three months old. They can also colonize the intestines and the female reproductive tract, increasing the risk for premature rupture of membranes during pregnancy, and transmission of the organism to the infant.
Post-streptococcal glomerulonephritis (PSGN) is an uncommon complication of either a strep throat or a streptococcal skin infection. It is classified as a type III hypersensitivity reaction. Symptoms of PSGN develop within 10 days following a strep throat or 3 weeks following a GAS skin infection. PSGN involves inflammation of the kidney.
However, both Streptococcus dysgalactiae and the Streptococcus anginosus group can possess group A antigen as well. Group A streptococci, when grown on blood agar, typically produce small (2–3 mm) zones of beta-hemolysis, a complete destruction of red blood cells. The name group A (beta-hemolytic) Streptococcus is thus also used. [1]
Neonatal meningitis is a serious medical condition in infants that is rapidly fatal if untreated.Meningitis, an inflammation of the meninges, the protective membranes of the central nervous system, is more common in the neonatal period (infants less than 44 days old) than any other time in life, and is an important cause of morbidity and mortality globally.
Which period is shorter depends on the disease. A person may carry a disease, such as Streptococcus in the throat, without exhibiting any symptoms. Depending on the disease, the person may or may not be contagious during the incubation period. During latency, an infection is subclinical.
Hemolyses of Streptococcus spp. (left) α-hemolysis (S. mitis); (middle) β-hemolysis (S. pyogenes); (right) γ-hemolysis (non-hemolytic, S. salivarius) Hemolysis is the breakdown of red blood cells. The ability of bacterial colonies to induce hemolysis when grown on blood agar is used to classify certain microorganisms.
