Xanthomonas vasicola pv. vasculorum (Xvv) is a gram-negative rod-shaped bacterium which has a single polar flagellum. It is a plant pathogen, causing both bacterial leaf streak of maize (corn) and sugarcane gumming disease. One outbreak in eucalyptus has been reported.^[1] Under experimental conditions it can infect sorghum, oats and some grass species. It is not currently a quarantine pathogen in any country, but it has already spread outside its native range and is highly adaptable to different environments.^[2]

The means of dispersal are not yet confirmed. Similar Xanthomonas pathogens are spread via wind-blown water droplets, irrigation, agricultural machinery and movement of infected plants. There are no known insect vectors.^[3]

Like other members of the Xanthomonas genus, it forms yellow colonies when grown on agar and secretes abundant xanthan exopolysaccharides.^[3]
