a
Expressed P1.7-2,4 PorA with the exception of deletions, insertions, or single-nucleotide substitutions around the VR2-4 sequence.
b
NST but determined to express P1.7-2,4 PorA by DNA sequencing.
c
Includes porA types P1.5,10, P1.21, 16, P1,18, 34, P1.7,16, P1.7-2,25, P1.21,15, P1.7-1,14, P1.22,28, and P1.21-2,28.
d
Isolates were NST and negative for all DNA probes used in DNA-DNA hybridization.
e
All 18 serosubtype P1.14 meningococcal isolates tested had restriction profiles identical to those for ST-457 meningococci.
