Effect of aqueous extract of green tea Camellia sinensis against bacteria Staphylococcus spp

Abstract

This study was conducted on green tea Camellia sinensis to determine the inhibition activity of plant aqueous extract against bacteria Staphylococcus spp.; The extract showed good inhibitory activity against S. aureus and S. epidermidis with 21.00 and 23.00 mm at 20 mg/mL, respectively with no significant differences with that of 10 mg/mL. The results compared to that of Ceftriaxone , Amoxicillin and Gentamicin antibiotics using agar well diffusion technique. The inhibition zone S.aureus was 10.00, 4.00, 7.00 mm for antibiotics Ceftriaxone , Amoxicillin and Gentamicin while S.epidermidis was 13.00, 5.00, 9.00 mm. The MIC results showed for the antibiotics ceftriaxone , Amoxicillin and Gentamicin which 8.00, 16.00, 5.00 and 6.00, 10.00, 3.00 mg/mL for S.aureus , S.epidermidis respectively.
