Streptococcus constellatus can sometimes cause serious invasive infections, as infections of the liver

and lung, brain abscesses, bacteraemia, endocarditis and intra-abdominal infections.

The study aimed to identify S.constellatus and to assess their susceptibility to several antibiotics.

Methods: In a 59-year-old patient hospitalized in intensive unit care for an epidural abscess, pus was

collected and bacterial were grown, then bacterial identifi cation was performed by routine laboratory methods.

Antimicrobial susceptibility testing was performed using standard disk diffusion method and MIC of

several antibiotics was determined by using the BioMérieux Vitek 2.

Results: S.constellatus was identifi ed in abscess and was resistant to penicillin, aminoglycosides,

macrolides, lincomycin, and fl uoroquinolones. Only vancomycin, pristinamycin and rifampin were active.

Conclusion: S.constellatus is considered commensal organism, but identifi cation and antibiotic

susceptibility of this species are necessary for good management of the abscess.
