【 摘 要 】
Nasal secretions of volunteers colonized by N. lactamica impaired the attachment of N. lactamica and of meningococci of groups A and B to oroepithelial cells. Bacterial adherence was found to be mediated by nonpiliated adhesins with antigen(s) which probably are shared by the strains tested. Although a strong attachment-inhibiting activity arises in their nasal secretions, volunteers remained colonized by N. lactamica. This evidence suggest that the eradication of Neisseria carriage is a multifactorial event.
