This study was designed in order to evaluate the effectives of two antibiotics and two
plant extracts against Mycoplasma galisepticum. Two commercial antibiotics
tilmicosin and enrofloxacin used for minimum inhibition concentration detection
against Mycoplasma galisepticum isolates. Two plants extracts also used for the same
purpose which is garlic and thyme. Using the micro-broth technique to determine the
growth of in vitro activities of tilmicosin, enrofloxacin, garlic and thyme against the
isolates of Mycoplasma gallisepticum. The results showed that the tilmicosin had
MICs of 7.8 mg/ml. while, enrofloxacin showed the best in vitro activity giving MICs
of 1.56 mg/ml. Garlic had MICs of 0.97 mg/ml which was the best of all results.
Lastly thyme had MICs of 15.6 mg/ml for the Mycoplasma gallisepticum. According
to the results all Mycoplasma gallisepticum strains are sensitive to all antibiotics and
plants extracts in different level and the highest effectiveness was for the garlic.
