Serotype and serovar distribution of Neisseria gonorrhoeae isolated from high-risk populations in Bangladesh

Neisseria gonorrhoeae, the causative agent of gonococcal infection, is known to frequently change their characteristics to evade host immune mechanism. Characterization of the clinical isolates of the organism can lead to identification of the circulating strains and often a sexual network in a community to help in designing the control strategy. Keeping in mind the above consideration, a total of 239 N. gonorrhoeae, isolated from high-risk populations, were characterized for serotypes and serovars by monoclonal antibodies against protein I of the organism. Majority of the serotypes were serotype B (142, 59.4%). Majority of the isolates showing resistance to at least one of the antibiotics tested were also serotype B (139, 59.2%), whereas, majority of the isolates showing resistance to any three of the antibiotics (multidrug resistant, MDR) (63%) was serotype A. A total of 41 different serovars were also identified and five of which (Arst, Bropt, Bopt, Arost, and Brop) included the highest percent (49.3%) of the isolates.
