R. Urwin et al., HETEROGENEITY OF THE PORB PROTEIN IN SEROTYPE-22 NEISSERIA-MENINGITIDIS, Journal of clinical microbiology (Print), 36(12), 1998, pp. 3680-3682
The genetic diversity of porB genes from meningococcal isolates charac
terized as serotype 22 was investigated by gene sequencing. This proce
dure identified seven distinct porB sequences, demonstrating variation
in the PorB protein recognized by the serotype 22 monoclonal antibody
. This is consistent with the genetic heterogeneity of serotype 22 men
ingococci reported previously.
