An Unusual Case Of A Ruptured Mycotic Aortic Aneurysm

Streptococcus equi is an aerobic bacterium of animal origin comprising two subspecies: zooepidemicus and equi. Human infections with this bacterium are very uncommon and result from direct contact with an infected animal or consumption of unpasteurized dairy products subsp. Although the zooepidemicus subspecies has been reported to cause sporadic infections in humans. the equi subspecies rarely infects other animal species. We report a case of ruptured mycotic aortic aneurysm in an elderly gentleman caused by the equi subspecies. We also review the literature on human infections caused by the Streptococcus equi species.
