abstract：:Neisseria gonorrhoeae and Neisseria meningitidis are exclusively human pathogens. A crucial property of the pathogenicity of neisserial infection is the ability to adhere to human epithelial cells. Pili mediate adherence of these bacteria to target cells and thereby promote colonization and infection of mucosal surfac...
