Apigmented bacterial colonies were obtained in Reunion Island from angular leaf lesions on Pepper tree ( Schinus terebenthifolius Radii), a member of Anacardiaceae . All isolates were identified as Xanthomonas campestris , using physiological and biochemical tests. These strains were reinoculated to Pepper tree leaves, and Koch postulates were verified. Furthermore, they were inoculated to mango leaves and produced lesions identical to those induced by Xanthomonas campestris pv. mangiferaeindicae , the causal agent of bacterial black spot of mangoes. Apigmented and pigmented strains of X. c. pv. mangiferaeindicae from Mango and Ambarella were pathogenic to Pepper tree. Strains isolated from Pepper tree were compared to X. c. pv. mangiferaeindicae , by means of phenotypic features (utilization of 147 carbon sources) and using a serological assay. A high homology among the strains was observed. Thus, It is concluded that strains isolated from Pepper tree belong to pv. mangiferaeindicae , and that Pepper tree is a host species for X. c. pv. mangiferaeindicae .
