Xanthomonas axonopodis is a rod shaped gram negative bacterium with polar flagella. The bacterium has a genome length approximately 5 Mbp. There are a number of types of citrus canker disease caused by different pathovars and variants of the bacterium:
- The Asiatic type of canker (Canker A), X. axonopodis pv. citri, caused by a group of strains originally found in Asia, is the most widespread and severe form of the disease.
- Cancrosis B, caused by a group of X. axonopodis pv. aurantifolii strains originally found in South America is a disease of lemons, key lime, bitter orange, and pomelo.
- Cancrosis C, also caused by strains within X. axonopodis pv. aurantifolii, only infects key lime and bitter orange.
- A* strains, discovered in Oman, Saudi Arabia, Iran, and India, only infects key lime.
