Experimental: A total of 60 male Wistar rats weighing 150+50 g (mean+SD) were randomly assigned into 10 groups of 6 rats each. Group 1, 2, 3, 7, 8, 9 and 10 were infected with one ml of S. typhi suspension with a concentration of 106 CFU/mL in phosphate buffered saline (PBS). Group 4, 5 and 6 which served as the Zero control, undiluted herbal control and diluted herbal control, respectively. Group 7 and were 8 were treated with 500 mg/Kg/bid and 250 mg/kg/bid herbal remedy, respectively, while group 9 and 10 were treated with equal volume of Ciprofloxacin and herbal remedy, 500 mg/kg/bid and 250 mg/kg/bid, respectively, orally twice daily for 7days. Bacterial loads in rectal swab, intestine and gall bladder, as well as the anti-S.typhi O and H serum antibodies of the test and control rats were evaluated at pre-infection, post-infection and post-treatment phases using standard microbiological and serological methods. Results: The outcome of this study showed that the administration of the herbal remedy (500 mg/Kg/bid) resulted in a significant reduction (P<0.001) in the rectal (1.8±04 Log CFU/mL), intestinal (4.25±0.05 Log CFU/Intestine) and gall-bladder (1.85±0.25 Log CFU/Gall-Bladder) bacterial load, as well as the anti-S. typhi O (93.3±22.3) and H (93.3±22.3) serum antibodies level of the test groups compared to the infection control (3.8±0.20 Log CFU/mL, 8.3±0.10 Log CFU/Intestine, 4.3±0.06 Log CFU/Gall-Bladder and 173.3±32.1, respectively). Recommended applications/industries: The outcome of this study further underscores the curative potential of the herbal remedy as claimed by the manufacturers and vendors.
