Production of H2O2 follows a growth phase-dependent pattern that mimics that of many
virulence factors of Streptococcus pyogenes. To gain greater insight into mechanisms …

The pneumococcus obtains its energy from the metabolism of host glycosides. Therefore,
efficient degradation of host glycoproteins is integral to pneumococcal virulence. In search of …
