Metabolic and transcriptomic profiling of Streptococcus intermedius during aerobic and anaerobic growth

Streptococcus intermedius, S. constellatus, and S. anginosus comprise the Streptococcus Milleri/Anginosus group (SMG). They are facultative anaerobic bacteria that asymptomatically colonize the upper respiratory, gastrointestinal and urogenital tracts. They are also common pathogens in pyogenic invasive infections, as well as pulmonary and urinary tract infections. Most SMG infections are polymicrobial and associated with co-infecting obligate …
