A collection of 26 strains of Xanthomonas campestris pv. mangiferaeindicae isolated from three different host species in eight countries was investigated for variation in isozyme patterns. Three enzyme systems were analysed: esterase (EST), phosphoglucomutase (PGM) and superoxide dismutase (SOD). Four groups of strains were identified: nonpigmented strains isolated from mango and pepper‐tree in Australia, Comores, India, Reunion Island, South Africa, and Taiwan; nonpigmented Brazilian strains from mango; nonpigmented strains from ambarella isolated in the French West Indies; heterogeneous yellow pigmented strains from mango (Brazil and Reunion Island). The value of isozyme profiling as markers of the pathogenicity groups in X. c . pv. mangiferaeindicae is discussed.
