Tea, Camellia sinensis (L) O. Kuntze (Theaceae) and coffee, Coffea arabica Linn. (Rubiaceae) possess antimicrobial activity in addition to various biological properties. In this study six strains of human pathogenic bacteria were assessed for their sensitivity to aqueous extracts of tea and coffee along with their preparations i.e. supplemented with milk and sugar. Antibacterial potential of the extracts has been compared with some of the commonly employed antibiotics. Bactericidal activity of the selected extracts was assessed by viable cell count method. Both tea and coffee inhibited bacteria to a variable extent and retained their antibacterial activity even after addition of milk and sugar. Equal effectiveness of tea/coffee extracts and their preparations justifies their potential as antibacterial agents.
