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.

Types of Xanthomonas campestris

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

• Xanthomonas campestris pv. armoraciae
• Xanthomonas campestris pv. begoniae A
• Xanthomonas campestris pv. begoniae B
• Xanthomonas campestris pv. campestris
• Xanthomonas campestris pv. carota
• Xanthomonas campestris pv. corylina
• Xanthomonas campestris pv. dieffenbachiae
• Xanthomonas campestris pv. hederae
• Xanthomonas campestris pv. hyacinthi
• Xanthomonas campestris pv. juglandis - the walnut blight
• Xanthomonas campestris pv. malvacearum or Xanthomonas citri subsp. malvacearum ^[1]
• Xanthomonas campestris pv. musacearum
• Xanthomonas campestris pv. nigromaculans
• Xanthomonas campestris pv. pelargonii
• Xanthomonas campestris pv. phaseoli
• Xanthomonas campestris pv. poinsettiicola
• Xanthomonas campestris pv. raphani
• Xanthomonas campestris pv. sesami
• Xanthomonas campestris pv. tardicrescens
• Xanthomonas campestris pv. translucens
• Xanthomonas campestris pv. vesicatoria

The former pv. citri, which causes citrus canker, was reclassified as X. axonopodis in 1995 Xanthomonas campestris#cite note-0. In 2006, the species designations for pv. citri and malvacearum were revised to X. citri and these pathovars are now referred to as subspecies Xanthomonas campestris#cite note-1.
