The antibacterial activities of extracts in Kenyan and Nigerian tea bags were tested for activity against six organisms; Pseudomonas aeruginosa, Staphylococcus aureus, Vibrio cholerea, Salmonella sp., Proteus sp. and Escherichia coli using the agar-gel diffusion method. The result obtained showed that 20% extract of both teas showed antibacterial activities against S. aureus, E. coli, Proteus sp and V. cholerea O1. Salmonella sp. and P. aeruginosa resisted the extracts.

Key words: Antibacteria activity, tea bag, Kenya, Nigeria
