Abstract
Food borne Infections caused by Salmonella spp. such as typhoid,
food poisoning remains a major public health problem, especially in developing
countries. The increasing resistance of this pathogen to commonly used
antibiotics has created an urgent need to explore alternative antimicrobial
agents. Home spices such as lemon, garlic, ginger, and onion are widely used in
daily diets and traditional medicine and were known to possess antimicrobial
properties. In the present study, the antimicrobial activity of fresh juice
extract of common household species viz. garlic (Allium sativum),lemon
(Citrus limon), onion (Allium cepa) and ginger (Zingiber
officinale) were tested by agar well diffusion method against the
typhoid fever causing Salmonella typhi bacteria. A total of 22 Salmonella
isolates were tested against three concentrations (100%, 50%, and 25%) of each
extract. Lemon extract exhibited the highest antibacterial activity, with a
maximum zone of inhibition of 23 mm, followed by garlic (20 mm), onion (21 mm),
and ginger (12 mm). The effectiveness of all extracts decreased with decreasing
concentration. Garlic and lemon extracts demonstrated strong inhibitory effects
against most isolates, while onion showed moderate activity and ginger showed
comparatively lower activity. Some isolates exhibited no sensitivity,
particularly at lower concentrations.These findings suggest that lemon and
garlic possess significant antimicrobial potential against Salmonella typhi and
may serve as effective natural alternatives to conventional antibiotics.
