Probable zoonotic aortitis due to group C streptococcal infection

Abstract

Human infections due to group C streptococcus (SGC) are unusual. Among them, vascular compromise, especially aortic involvement, is extremely rare. A case of microbial aortitis with aneurysm formation, likely secondary to a SGC soft tissue infection, in a 61-year-old patient who was caring for a purulent leg wound of his horse, is presented. He was successfully treated with antibiotics and in situ aortic replacement with a prosthetic graft and an omental wrap. He remains well almost 2 years after surgical intervention. Aortic infection caused by SGC is a rare condition that can be successfully treated with in situ prosthetic graft replacement.

Aortic graft infection and mycotic aneurysm with Streptococcus equi zooepidemicus: two cases with favorable outcome of antibiotic treatment

“…15 So far, there have been very few reports about infected vascular grafts or aneurysms with this etiology. 68 We present two patients, one with an infected Y-graft four years after an open operation for an abdominal aortic aneurysm (AAA), and one with a presumably mycotic aneurysm of the abdominal aorta, treated with an endograft.…”
