Antibacterial capacity in amniotic fluid in normal and complicated pregnancies

Abstract:
The antibacterial activity against Escherichia coli K 12 in 153 samples of amniotic fluid (AF) in 15 to 40 weeks of pregnancy were investigated by a new micromethod. Fifty-six mothers had an uncomplicated pregnancy while various complications (maternal diabetes, cholestasis of pregnancy, pregnancy induced hypertension, blood group isoimmunization and fetal growth retardation) were present in 97 cases. A significant (p less than 0.001) improvement of antibacterial activity was observed with advancing pregnancy. The highest antibacterial activity in AF was observed in cases with intrauterine growth retardation. In other respects the effect of various diseases was negligible.

Surface Membrane Barriers
The outer layer of the skin, the epidermis, is a robust barrier comprising layers of closely packed keratinized cells. This dense arrangement prevents microbes from penetrating the body. The periodic shedding of epidermal cells...
Development of Immunocompetence
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
