Lactoferrin as an indicator of septicemia and endotoxemia in pigs.
The levels of plasma lactoferrin (LF) in response to endotoxin and Escherichia coli infusions in piglets were studied to obtain exact time relation of plasma LF increase in relation to start of endotoxin and E. coli infusions. A new enzyme-linked immunoassay of swine LF is presented. 13 piglets had a 10-fold rapid increase of plasma LF concentrations after 0.25 mg/kg endotoxin intravenous infusion. The initial rise was 3.4 mg/l/h. 14 piglets, receiving 1 x 10(11) E. coli intravenously, showed a higher increase of plasma LF concentrations, amounting to 6-9 mg/l/h. Thus, plasma LF was an early marker of septicemia and endotoxemia.
