An evaluation for Antibacterial activity of aqueous extract of Green, Black, Red, and Tea Leaves against gram positive bacteria Staphylococcus aureus, Staphylococcu sepidermidis, Streptococcus pneumonia, Streptococcus feacalis, Streptococcus mutanus, Streptococcus feacalis and gram negative bacteria Escherichiacoli, Salmonella typhi, Moraxalliacatarralis, Pseudomonas aeroginosa, Proteus mirabilis, Klebsiella pneumonia, Enterobacter spp. Acinetobacter, Serratia spp.
Three types of aquatic extract of green, black and red tea leaves were used to determine the antibacterial activity. Agar well diffusion method was used in this study.
All three types of tea aquatic extract exhibited excellent and best antibacterial activity against both gram positive and gram negative bacteria and show good inhibition zone and better than the effect of ciprofloxacin against different types of bacteria.
Aqueous extract of Green, Black, Red, and Tea Leaves show high antibacterial activity against both gram positive and gram negative bacteria, therefore most types of tee can provide protection to a certain extent against our natural enemies like bacterial pathogens.
