Quizplus · Accepted Answer

Serogrouping is the best way to identify the various strains of N. meningitidis, as different strains can be distinguished by the type of capsular polysaccharide they possess. Gram staining and fluorescent antibodies can be used to visualize the bacteria, but cannot distinguish between different strains. Titering is a method of measuring the concentration of antibodies in a sample, and signs and symptoms alone cannot be used to identify the specific strain of the bacterium causing the infection.
