A Case of Serratia marcescens Endocarditis in a Nonintravenous Drug-Using Male Patient and Review of Literature.

Hospital-acquired infections by Serratia species are a common problem in medical practice and have been attributed to specialized interventional procedures. Taking into consideration the patient's immunocompetence and lack of intravenous drug use, it is possible that bacteremia could be attributed to a medical procedure. Moreover, in contrast to most cases described in the literature, no surgery was performed.
