Type VI secretion system killing by commensal Neisseria is influenced by expression of type four pili
Type VI Secretion Systems (T6SSs) are widespread in bacteria and can dictate the development and organisation of polymicrobial ecosystems by mediating contact dependent killing.In Neisseria PREGNANCY CARE PROBIOTIC species, including Neisseria cinerea a commensal of the human respiratory tract, interbacterial contacts are mediated by Type four pili
