The susceptibilities of Salmonella typhi and other pathogens to antibiotics and hot aqueous extract of Hibiscus sabdariffa were investigated using agar diffusion and agar well diffusion methods respectively. Salmonella typhi was sensitive to ampicillin, cetriaxone, ciprofloxacin, gentamycin of ofloxacin and perfloxacin. Nitrofurantoin, ampicillin, clarithomycin and augumentin are resistant. Escherichia coli, Klebsiella spp, and Staphylococcus aureus were sensitive to 50%, 70% and 60% of the antibiotics respectively. Pseudomonas aeruginosa was resistant to all antibiotics.
Long before mankind discovered the existence of microbes, the idea that plants have some healing potentials, i.e. that they contain what we will currently characterize as antimicrobial principle was well accepted (Doughari, mahmood & Tyoyina, 2011). In whatever manner early man gained his knowledge of the curative powers of plants, one must assume that the was able thereafter to recognize the plant, since the detailed flora available today, were not in existence then (Sofowora, 2008). The use of higher plants and their extracts to treat infectious diseases is an age old practice in traditional African medicine (Onyeagba, ugbogu, Okeke & Iroakasi, 2004).
