Bacteraemia with Moryella indoligenes and Fastidiosipila sanguinis: a case report.

Moryella indoligenes and Fastidiosipila sanguinis are obligate anaerobic Gram-positive bacteria that are rarely involved in human infections. We present the first case of bacteraemia with M. indoligenes , which was part of a co-infection with F. sanguinis . Both micro-organisms were identified by 16S rRNA gene sequencing and M. indoligenes was also identified by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS). Prostate cancer involving the bladder suggests that the urinary tract was the most likely primary site of infection.
