Figure 1.

Legend. Only exemplar atypical anatomical sites infected by pathogenic and commensal Neisseria species are depicted. Corresponding references for these and other clinical case reports of unusual infections with Neisseria species are listed in Table 1. Characteristic (typical) infections with gonococcus (gonorrhea) and meningococcus (meningitis and septicemia) are not included. Many of the unusual gonococcal infections are either associated with preceding DGI or considered the cause of subsequent gonococcal septicemia and/or other manifestations of DGI. Some clinical cases of unusual meningococcal infections are either associated with preceding meningococcaemia or further develop sepsis (SMD) as a consequence of the corresponding primary infection (refer to the main text for more details).
