Streptococcus anginosus and Coxiella burnetii vascular graft co-infection

Vascular graft infections are rare complications, usually associated with a monomicrobial pyogenic culture. We report a case of vascular graft co-infection with Streptococcus anginosus and Coxiella burnetii, complicated by an aorto-duodenal fistula. Screening for chronic C. burnetii co-infection in at-risk patients might prevent adverse long-term outcomes.
