( Serovar)
A serovar or serotype is a group of microorganisms or viruses based on their cell surface antigens. Serovars allow the epidemiologic classification of organisms to the sub-species level. [1] A group of serovars with common antigens is called a serogroup. Serovars may be established based on virulence factors, lipopolysaccharides in Gram-negative bacteria, presence of an exotoxin (pertussis toxin in Bordetella pertussis, for example), plasmids, phages, or other characteristics which differentiate two members of the same species. [1][2] Serotypes were discovered by the American microbiologist Rebecca Lancefield in 1933.[3] name="References" id="References">
