Fluorescent monoclonal antibody test for the confirmation of Neisseria gonorrhoeae.

The Microtrak fluorescein labelled monoclonal antibody test for the culture confirmation of Neisseria gonorrhoeae was evaluated with 157 clinical isolates of oxidase-positive Gram-negative diplococci, including 110 strains of N. gonorrhoeae. Seventy-eight stock cultures of neisseria were tested to confirm the results from clinical samples. The test gave a specificity of 100% and sensitivity of 98%. Only four strains of the rare serovar Behj were non-reactive. As the prevalence of this serovar influences the utility of the test, the rarity of this serovar in different geographical locations is discussed.
