In - Vitro Antibacterial bustle of Ethanol Extract of leaf cassia fistula was premeditated. Four Gram-positive and Five Gram-negative bacteria namely Bacillus megaterium, Bacillus subtiIis, Streptococcus β - haemolyticus, staphylococcus aureus, Salmonella typhi, Shigella dysenteriae, Shigella shiga, Escherichia coli and Pseudomonas aeruginosa were practiced. The Extract was unsuccessful at concentration of 30μg/disc but showed moderate to good activity at concentration of 200μg/disc against the tested pathogens. The leaf extract revealed better activity displaying their zone of inhibitions 9-18 mm and largest zone was shown against Shigella Dysenteriae (18 mm). From these findings it is investigative that Cassia fistula may have antibacterial principles that could be useful in microbial diseases.
