Host-to-Host Transmission of the Pneumococcus-New Victims of a Toxic Relationship.


Host-to-host transmission is critical for survival of the human-adapted bacterium Streptococcus pneumoniae. In this issue of Cell Host & Microbe, Zafar et al. (2017) show that transmission is dependent on nasopharyngeal inflammation elicited by the toxin pneumolysin, causing increased shedding and enhanced survival of the bacterium in the environment.
