Neisseria meningitidis can cause potentially fatal systemic disease. Early diagnosis and prompt antimicrobial intervention are critical for favorable clinical outcomes. Antibiotic resistance has been reported for penicillins 1 , tetracycline 2 , and sulfonamides 3 , as well as quinolones 4 and rifampin 5. Neisseria gonorrhoeae expresses a single porin, PorB.

The class 3 protein PorB is an important component of the meningococcal outer membrane. The structural gene porB encoding the class 3 protein has been cloned using primers suitable for the amplification of the corresponding chromosomal fragment by the polymerase chain reaction PCR. The complete nucleotide sequence was determined and predicts a mature protein of amino acids, preceded by a signal peptide of 19 residues.
