Minimum inhibition concentration of two antibiotics and two plants extract against Mycoplasma galisepticum in Iraq

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.
