Signalment:16-year-old, 46 kg, male Huacaya alpaca
History:The alpaca was housed with another alpaca and lived in close proximity with wild boars. He had previous “suspect episodes of meningeal worm”, which were never confirmed, but were treated with monthly ivermectin for the last three years. A week before presenting to necropsy, the animal started to present with a base wide stance and posterior paresis. Despite treatment with fenbendazole and oxytetracycline, the clinical signs progressed to recumbency and hence the animal was euthanized.
Gross Lesions:Systemic multifocal, random, mineralizing granulomas
