Frequent interspecific genetic exchange between commensal neisseriae and Neisseria meningitidis
1 Jun 2000
Abstract excerpt
Natural sequence variation was investigated among serogroup A subgroup IV-1 Neisseria meningitidis isolated from diseased patients and healthy carriers in The Gambia, West Africa. The frequencies of DNA import were analysed by sequencing fragments of four linked genes encoding the immunogenic outer membrane proteins TbpB (transferrin binding protein B) and OpaA (an adhesin) plus two housekeeping enzymes....
