Isolation of bacterial from eye infections (conjunctivitis) was carried out in this study39 specimens (55.71%) gave positive bacterial culture from totally(70) samples. We found that staphylococcus aureus and staphylococcus epidermidis in 35.71,20% respectively from the total isolates.
Antibacterial activities of the antibiotics vancomycin, oxacillin, cephalothgin chloramphenicol, tobramycin, ciprofloxacin Staph. Aureus and Staph. Epidermidis shows resistance rate about (4,12, 16, 28 , 8, 8% ) and (7,14,14.28 ,35.7,28.57,42.85,21.42%) respectively.
The inhibition ability of black tea alcoholic extract against Staph. aureus and Staph. epidermidis isolates at concentration (10, 20, 40, 80, 100%) were (13,15,17,19,27) mm, (10,14,16,18,24 ) mm of inhibition zones respectively.
