The bactericidal activity of sera of healthy neonates and newborns with hyperbilirubinaemia to E. coli. 1979

I Miler, and J Vondrácek, and L Hromádková

Cord and newborn sera were found to possess a significantly decreased in vitro bactericidal activity to E. coli as compared to sera of adults. Hyperbilirubinaemia in neonataes suffering from both Rh and ABO incompatibility results in a further significant impairment of bactericidal activity of their sera in comparison to healthy newborn infants. Exchange transfusion considerably improved this serum antibacterial activity. The possible mechanism of toxic action of unconjugated bilirubin on the cells of the immune system is discussed.

D007567	Jaundice, Neonatal	Yellow discoloration of the SKIN; MUCOUS MEMBRANE; and SCLERA in the NEWBORN. It is a sign of NEONATAL HYPERBILIRUBINEMIA. Most cases are transient self-limiting (PHYSIOLOGICAL NEONATAL JAUNDICE) occurring in the first week of life, but some can be a sign of pathological disorders, particularly LIVER DISEASES.

D001770	Blood Bactericidal Activity	The natural bactericidal property of BLOOD due to normally occurring antibacterial substances such as beta lysin, leukin, etc. This activity needs to be distinguished from the bactericidal activity contained in a patient's serum as a result of antimicrobial therapy, which is measured by a SERUM BACTERICIDAL TEST.

D004926	Escherichia coli	A species of gram-negative, facultatively anaerobic, rod-shaped bacteria (GRAM-NEGATIVE FACULTATIVELY ANAEROBIC RODS) commonly found in the lower part of the intestine of warm-blooded animals. It is usually nonpathogenic, but some strains are known to produce DIARRHEA and pyogenic infections. Pathogenic strains (virotypes) are classified by their specific pathogenic mechanisms such as toxins (ENTEROTOXIGENIC ESCHERICHIA COLI), etc.	Alkalescens-Dispar Group,Bacillus coli,Bacterium coli,Bacterium coli commune,Diffusely Adherent Escherichia coli,E coli,EAggEC,Enteroaggregative Escherichia coli,Enterococcus coli,Diffusely Adherent E. coli,Enteroaggregative E. coli,Enteroinvasive E. coli,Enteroinvasive Escherichia coli
