Respiratory Infection With Nocardia cyriacigeorgica in an Immunosuppressed HostForrester, Joseph Derek BA*; Forrester, Joseph Michael MD†Infectious Diseases in Clinical Practice: November 2011 - Volume 19 - Issue 6 - p 423-425 doi: 10.1097/IPC.0b013e31820a52e3 Case Reports Abstract Author Information Nocardia cyriacigeorgica is a recently redesignated species originally recognized as the Nocardia asteroides antibiotic susceptibility type VI isolate. We describe the case of N. cyriacigeorgica pneumonia in an immunosuppressed host. Although Nocardia species have long been recognized as uncommon causes of pneumonia, recent species distinctions elucidated by molecular typing techniques have clarified more appropriate antibiotic therapy and treatment for specific Nocardia species.
