Abstract
Purpose: To evaluate the antibacterial potentials of fourteen ethnobotanically selected plants traditionally used in different parts of Côte d’Ivoire for the treatment of typhoid fever and gastrointestinal disorders.Method: The antimicrobial activity of the extracts of the plant was tested against a collection strain of Salmonella typhimurium, a clinical strain of Salmonella typhi and Pseudomonas aeruginosa by macrobroth dilution method. Minimum inhibitory concentration (MIC) and minimum bactericidalconcentration (MBC) were determined. Results: All the plants had bactericidal activity against at least one of the test microorganisms with both MIC and MBC ranging from 2.5 to > 80 mg/ml. Among the plant extracts, Terminalia glaucescens. (Combretaceae) Bersama abyssinica subsp. paullinioides (Melianthaceae ) and Abrus precatorius (Fabaceae) showed the most promising broad spectrum antibacterial properties, inhibiting all of the strains tested, especially S. Typhi and P. aeruginosa, with MBC ranging from 2.5 to 5 mg/ml. Conclusion: The findings provide support for the use of these plants in traditional medicine for treatment of typhoid fever and gastrointestinal disorders, and are thus, potential sources of drugs that would need to be subjected to further studies.Keywords: Antimicrobial activity, Ivorian medicinal plants, MIC, MBC.
Highlights
Medicinal plants have been known for their healing and/or disease-curing qualities for centuries
The objective of the present study was to evaluate the antibacterial activity of the extracts of some plants used in Côte d’Ivoire traditional healthcare system, against a group of pathogenic bacteria
These plants are used by the indigenous people in different parts of Côte d’Ivoire for the treatment of infectious diseases such as cholera, diarrhoea, dysentery and other gastrointestinal disorders [4,5]
Summary
Medicinal plants have been known for their healing and/or disease-curing qualities for centuries. Many readily available plants in Côte d’Ivoire are used in traditional folklore medicine for the treatment of typhoid fever and gastrointestinal disorders such as cholera, diarrheoa and dysentery [2,3]. The objective of the present study was to evaluate the antibacterial activity of the extracts of some plants used in Côte d’Ivoire traditional healthcare system, against a group of pathogenic bacteria. These plants are used by the indigenous people in different parts of Côte d’Ivoire for the treatment of infectious diseases such as cholera, diarrhoea, dysentery and other gastrointestinal disorders [4,5]. A total number of fourteen species of plants belonging to eleven different families were tested on S. typhimurium, S. typhi and P. aeruginosa
