FAQ
Frequently Asked Questions
It is a specific type of strain, one defined by biochemical/physiological traits. 'Strain' is a broader, more general term.
Almost exclusively in technical microbiology journals, public health documents, or plant pathology reports.
Typically no. The term is most commonly applied to bacteria and some other microorganisms. Viruses are usually classified by serotypes, genotypes, or strains.
A biovar is defined by biochemical tests, a serovar by antigenic properties, and a pathovar by the specific host plant it infects. They are different methods of sub-species classification.
A strain or type of microorganism (like a bacterium) that is distinguished from others of the same species based on its specific biochemical or physiological characteristics.
Biovar is usually technical/scientific (specialist) in register.
