A pathovar is a
bacterial strain or set of strains with the same or similar characteristics, that is differentiated at infrasubspecific level from other strains of the same species or subspecies on the basis of distinctive pathogenicity to one or more
plant hosts.
Pathovars are named as a ternary or quaternary addition to the species binomial name, for example the bacterium that causes
citrus canker ''Xanthomonas axonopodis'', has several pathovars with different host ranges,
''X. axonopodis'' pv. ''citri'' is one of them; the abbreviation 'pv.' means pathovar.
