Amongst serious biotic factors deteriorating crop yield, the most destructive pathogen of rice is Xanthomonas oryzae pv. oryzae which cause bacterial leaf blight of rice. This study involved pathogenicity and some antibiotic reactions. BLB infected leaves were collected from Sindh, province Pakistan such as; Hyderabad, Tando Muhammad Khan, Thatta and Badin distracts. Fourteen bacterial colonies were selected from the isolation and designed as Xoo-1 to Xoo-14. Result of pathogenicity basmati 2000 variety was used. One strain Xoo-3 found resistance and eight strains Xoo-1 Xoo-2 Xoo-4 Xoo-5 Xoo-6 Xoo-7 Xoo-8 Xoo-9 were found moderately resistance and five strains were moderately susceptible Xoo-11 Xoo-12 Xoo-13 Xoo-14 Xoo-15. All strains showed different level of reaction against Ampicillin and Gentamycin.
