Abstract

 

The antibacterial properties of Tetradenia riparia, the most frequently used plant by the traditional healer for the treatment of chest and cough related infections was reported in this study. The plant was investigated to evaluate claims made by the users as a remedy for chest and cough related infections. Ten bacterial strains (five gram-positive and five gram-negative) were used for the antibacterial assays. All the extracts showed some activity against the bacteria tested at concentrations ranging from 1.0 to 10.0 mg/ml, with the exception of dichloromethane extract which did not inhibit any of the microorganisms used. The antibacterial properties of the plant extracts were more visible with the gram-positive bacteria while gram-negative bacteria showed more resistance to the treatments especially at low concentration. The resistance of gram-negative bacteria has been attributed to the composition of their cell walls.
