Xanthomonas campestris is bacterial species that causes a variety of plant diseases. Available from the NCPPB and other international culture collections such as ICMP, ATCC, and LMG in a purified form, it is used in the commercial production of a high-molecular-weight polysaccharide – xanthan gum – that is an efficient viscosifier of water and that has many important uses, especially in the food industry. It causes spots on the infected plant.

(pv. means pathovar, a type of classification based on the host plant that is attacked by Xanthomonas campestris)

The former X. c. pv. citri, which causes citrus canker, was reclassified as X. axonopodis in 1995. In 2006, the species designations for X. c. pv. citri and X. c. pv. malvacearum were revised to xes. citri and these pathovars are now referred to as subspecies.
