a
ET, electrophoretic type; —, the ET of strain B1940 does not correspond to any well-known clone associated with a high incidence of disease.
b
Reactivities with MAbs were determined by indirect immunofluorescence (for 9-2-L379) and by Western blot analysis (for B306, 4B12/C11, and SM1). 9-2-L379 is reactive with LPS of immunotype L3,7,9 and was kindly provided by W. D. Zollinger (Washington, D.C.); B306 and 4B12/C11 bind to meningococcal Opc and Opa, respectively, and were provided by M. Achtman (Berlin, Germany); and SM1 binds to neisserial pilin of class I pili (donation of M. Virji, Bristol, United Kingdom).
