Abstract

This study aimed to treat the pathogenic activity of salmonella by plant extracts. Salmonella is an essential human pathogenic bacterium that causes various types of infections. Many plants have antimicrobial activities that can be used against the microbes. Salmonella was isolated from the sewage water and identified by different morphological and biochemical tests- Gram staining, sugar fermentation, catalase, MR, motility etc. Six plant samples Cardamom (Elettaria Cardamomum), Cloves (Syzygium aromaticum), Ginger (Zingiber officinale), Onion (Allium sepa), Turmeric (Curcuma longa) and Tulsi/holy basil (Ocimum tenuiflorum) were taken for antimicrobial activity against Salmonella. An antimicrobial susceptibility test was applied to see which plants were hyperactive to resist it. The mean value of the Zone of inhibition seen was Ginger- 17.75mm, Onion-17.5mm, Cardamom-17mm, Turmeric-9mm, Tulsi- 7mm and Clove-0mm respectively. The highest antimicrobial potential was observed for ginger and the lowest was for Tulsi. So Ginger, Cardamom and Onion can be used in the future to cure Salmonella infections.
