Possible Prosthetic Valve Endocarditis by Pandoraea pnomenusa and Specific Virulence Mechanisms

Bacteremia by Pandoraea spp. has rarely been described before. We report the first case of a P. pnomenusa possible prosthetic valve endocarditis, according to the modified Duke criteria, in a 37-year old male injecting drug user suffering from recurrent endocarditis. Furthermore, we demonstrate biofilm formation by the P. pnomenusa isolates of this patient and investigate antibiotic resistance.

Automated summary

This study presents the first case of possible prosthetic valve endocarditis caused by Pandoraea spp. in a 37-year-old male injecting drug user with recurrent endocarditis. Biofilm formation and antibiotic resistance of the P. pnomenusa isolates from this patient were also investigated.
