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

TI Mbata

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.
