Effect of endotoxin administration in pregnant camels

Abstract EN

Intravenous administration of Escherichia coli endotoxin at a dose of 0.05 lg / kg bodyweight to pregnant camels resulted in abortion.

The injection of endotoxin caused significant increases in the plasma concentration of 13, 14-dihydro-15-prostaglandin F2a, the metabolite of prostaglandin F2a (PG F2a) and cortisol and a significant decrease in the concentration of progesterone.

It is suggested that endotoxin caused abortion in camels was a consequence of endotoxin induced PG F2a secretion resulting in luteal regression and decreased progesterone concentration.
