Abstract
Different crude extracts of Nigella sativa were tested for antimicrobial effectiveness against different bacterial isolates. These isolates comprised 16 gramnegative and 6 grampositive representatives. They showed multiple resistance against antibiotics, specially the gramnegative ones. Crude extracts of Nigella saliva showed a promising effect against some of the test organisms. The most effective extracts were the crude alkaloid and water extracts. Gramnegative isolates were affected more than the grampositive ones.
