Abstract

A xylem-limited bacterium serologically related to strains of Xytetta fastidiosa has been associated previously with citrus variegated chlorosis, a new and potentially serious disease of citrus in Brazil. When isolated and grown on PW (periwinkle wilt) medium, this gram-negative bacterium measured 0.4×4 μm and was indistinguishable based on colony appearance from reference strains of X. fastidiosa obtained from the American Type Culture Collection, Rockville, MD. The bacterium also had a rippled cell wall typical of X. fastidiosa and induced symptoms typical of citrus variegated chlorosis in sweet orange after artificial inoculation [...]
