Retrospective study of 103 presumed cases of tick (<i>Ixodes holocyclus</i>) envenomation in the horse

Abstract

In general, tick envenomation in horses follows the geographic distribution of Ixodes holocyclus. Tick antiserum administered at >0.5 mL/kg increases the odds of survival. It would appear that the complications associated with managing a recumbent horse increase the odds of death.
