Isolated organisms were then subjected to antibiotic sensitivity test against seven different standard antibiotics. Most of the strains tested were resistant to four antibiotics; 93.75% were resistant to co-trimaxazole, while 90.62% were resistant to cephotaxime, nalidixic acid and Tetracycline each. In this study, ciprofloxacin and gentamicin were found to be the most potent drugs, (78.125%) were sensitive to Ciprofloxacin &amp; (78.125%) were sensitive to gentamicin. Antimicrobial activity of bark extract of <em>T. arjuna</em> against 13 selected isolates of <em>Salmonella </em>were then determined. During the course of the anti-microbial screening it was found that among the 13 selected isolates, <em>Salmonella</em> (L3-B1), <em>Salmonella</em> (L5-X4), <em>Salmonella</em> (F-X2) and <em>Salmonella</em> (S2-B1) showed good sensitivity to crude extract of<em> T. arjuna.</em></p> <p>International Journal of Natural Sciences (2012), 2(3):71-75</p> DOI: <a href="http://dx.doi.org/10.3329/ijns.v2i3.12135">http://dx.doi.org/10.3329/ijns.v2i3.12135</a> ER -
