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]
