Variation in Streptococcus pneumoniae susceptibility to human antimicrobial peptides may mediate intraspecific competition.

Abstract excerpt

Streptococcus pneumoniae is a facultative pathogen inhabiting the nasopharynx of humans where it is exposed to a range of antimicrobial peptides (AMPs) of the innate immune response. It is possible therefore that the susceptibility of strains to AMPs plays a role in determining their ability to c...
