the level of inhibition against isolates From the results
there is variation in the degrees of antibacterial activities
of the extracts on the isolates The variation is presumed
to be due to different active compounds present in these
plants Ethanol extracts of O. gratissimum showed more
antibacterial activity against S. aureus than E. coli. This
result is in agreement to Agatemor (2009) where it was
reported that gram negative bacteria are more resistant
than gram positive bacteria to the essential oil which are
antimicrobial agents
