What symptom does pregnant woman B group streptococcus have

summary

The scientific name of group B streptococcus in medicine is Streptococcus agalactiae, which occurs in pregnant women and can cause many diseases of newborns. In 1938, fry first reported 3 cases of death of postpartum endocarditis caused by group B streptococcus infection, which confirmed that group B streptococcus is a human pathogenic bacteria. After decades of research, we found that group B Streptococcus can cause neonatal sepsis, pneumonia, meningitis, and even death. Let's share some experience.

What symptom does pregnant woman B group streptococcus have

First, mild infection is asymptomatic bacteremia, while pneumonia is difficult to distinguish from hyaline membrane disease. Severe infection is characterized by severe perinatal asphyxia (complicated with pneumonia, coma, shock), septic shock or continuous fetal circulation.

Second, 60% of late-onset infections were meningitis, mainly type III, which could not be distinguished from other pathogens. Others may have osteomyelitis, urinary tract infection and other localized lesions.

Third: after infection, because the children's resistance is very low, so it is easy to make meningeal infection, meningeal involvement can have convulsions, drowsiness, coma, milk refusal, anterior fontanelle convex, but can not be based on clinical diagnosis, all suspected of early-onset or late-onset neonatal sepsis should do lumbar puncture.

matters needing attention

In view of the fact that the infection caused by this bacterium is not limited to bovine mastitis, and the polysaccharide in its cell wall belongs to group B of antigen structure classification, group B streptococcus (GBS) is generally used to replace the original name of Streptococcus agalactiae.
