Intracellular replication of Streptococcus pneumoniae inside splenic macrophages serves as a reservoir for septicaemia (2018)
Journal Article

Bacterial septicaemia is a major cause of mortality, but its pathogenesis remains poorly understood. In experimental pneumococcal murine intravenous infection, an initial reduction of bacteria in the blood is followed hours later by a fatal septicaem...
