Antibacterial Activities of selected Medicinal Plants Against Salmonella typhi, Salmonella paratyphi A, B and C, Clinical Isolates in North Central, Nigeria.

The aim of the research was to investigate antibacterial activities and phytochemical properties aqueous ethanolic extracts Mango (Mangifera indica) Neem (Azadirachta leaves, on clinical isolates Salmonella typhi, paratyphi A, B C, in Lafia, Nigeria. agar well diffusion technique used analyses were done triplicates. At highest extract concentration 80 mg/ml, S. showed inhibition zones 29.4±0.1mm 30.0±0.01 mm respectively, while exhibited 14.4±0.2, 21.2±0.4, 13.4±0.1 18.0±0.03, 20.0±0.04, 21.0±0.04 mm, respectively. lower 10 8.4±0.01 9.0±0.1 9.5±0.01, 9.1±0.01, 6.2±0.01 9.0±0.01, 9.0±0.01 respectively leaf extract. MIC MBC, against organisms 2.5 5.0 qualitative results presence alkaloids, anthraquinones, carbohydrates, cardiac glycosides, flavonoids, tannins, terpenoids saponins. Conclusively, studied medicinal plant bactericidal all tested organisms, this supports claim by traditional medical practitioners vendors use plants for cure typhoid fever. Further studies are recommended toxicity safe dosage regimen since infusion is taken orally people   Key words: fever, constituents, bacteria, plants.
