Serovars

Definition

Serovars are distinct variations within a species of bacteria or viruses, identified by differences in their surface antigens. They are used to classify microorganisms for epidemiological studies and disease tracking.

5 Must Know Facts For Your Next Test

1. Serovars can be differentiated using serological assays such as agglutination tests.
2. The term 'serovar' is often used interchangeably with 'serotype'.
3. Identifying serovars helps in understanding the spread and impact of infectious diseases.
4. Proteobacteria, a major phylum of Gram-negative bacteria, includes many species that have multiple serovars.
5. Serovars play a crucial role in vaccine development as they help determine which strains need to be targeted.
