The Role of Feral Swine in Human Aortic Infection With Brucella Species.

Abstract

Brucellosis is one of the most common zoonotic infections in the world. Human infections are the result of direct exposure to infected animals or ingestion of unprocessed dairy products. While Brucella sp. infection has largely been eliminated from commercial cattle and swine with aggressive vaccination, there is a significant prevalence of Brucella sp. infection in the expanding population of feral swine in the US. We report the surgical treatment of a ruptured mycotic aneurysm of the abdominal aorta due to Brucella suis in a woman living in a rural community with a large population of feral swine. Vascular surgeons should be aware that brucellosis can result in arterial infection and should be considered in the differential diagnosis in patients with a history of exposure to feral swine or the ingestion of unprocessed dairy products.
