A Longitudinal Study of Neisseria Meningitidis Carriers in Submarine Crews
نویسندگان
چکیده
A total of 342 men from both the Blue and Gold crews of the Polaris submarine USS MARIANO G. VALLEJO (SSBN-658), were surveyed periodically over a 13-month period for the causative organism of meningitis (Neisseria meningitidis). It was found that the overall carrier rate was 26 percent, with four percent chronic carriers, 28 percent always negative, and 68 percent intermittent carriers. Of all isolates, 21 percent were resistant to sulfadiazine. Group B was the predominant serogroup. The closed environment did not appear to influence the carrier rate or create a selective advantage for any one serogroup. It may influence the development of resistant organisms positively. It is concluded that N. meningitidis carrier rate in seasoned military personnel is 26 percent. The three factors of crowding, recruit seasoning, and the presence of chronic carriers are discussed.

Neisseria meningitidis is a major causative agent of bacterial septicemia and meningitis in humans. Currently, there are no vaccines to prevent disease caused by strains of N.meningitidis serogroup B. The Class 1 Outer Membrane Protein (OMP) has been named porA which is a cation selective transmembrane protein of 45 KDa that forms trimeric pore in the meningococcal outer membrane. PorA from ser...
