Abstract
Horses are very sensitive to Gram-negative bacterial lipopolysaccharides (LPS) which, when introduced into the blood stream, induce several responses mediated by endogenous pro-inflammatory mediators originating from bacteriolysis or granulocyte disintegration. Intraperitoneal LPS injection was used to mimic the proposed route of endotoxin travel in clinical cases. The clinical signs and laboratory findings demonstrated a dose- dependent effect and were more consistently observed with 500 ng/kg of LPS. We conclude that intraperitoneal injection of LPS produces the same endotoxic status as obtained by systemic injection of LPS, even during the initial phase.
