Endocarditis caused by Finegoldia magna (formerly Peptostreptococcus magnus): diagnosis depends on the blood culture system used

Diagn Microbiol Infect Dis. 2003 Sep;47(1):359-60. doi: 10.1016/s0732-8893(03)00091-9.

Abstract

We present a patient with prosthetic valve endocarditis caused by Finegoldia magna (formerly Peptostreptococcus magnus). Blood cultures in the BacT/ALERT and BACTEC 9240 system were negative. We therefore tested different blood culture systems: F. magna grew in the SEPTI-CHEK BHI-S and in the ISOLATOR, but not in the BacT/ALERT system.
