Abstract
The effects on seven horses of bites by the European adder (Vipera berus) are described and compared with previously available information. The clinical signs varied from local swelling and mild systemic signs to severe systemic signs, including systemic inflammatory response, severe tissue necrosis, ventricular tachycardia and dysphagia. Two of the horses were treated with ‘Zagreb’ antiserum, and three that were not treated with antiserum were euthanased owing to complications related to the bites.
