Preliminary studies of the antibacterial activities of processed Kenyan and Nigerian tea

Abstract

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.
