An example of an MIC endpoint for tiamulin against L. intracellularis strain CUHE01_SW13 at passage 6. Photographs of McCoy cells infected with L. intracellularis growing in the presence of tiamulin with concentrations ranging from 2 μg/ml to 128 μg/ml. There was no L. intracellularis growth in cells treated with tiamulin at concentrations ranging from 16 μg/ml to 128 μg/ml. The numbers of HICs dramatically increased at the concentration of 4 μg/ml (> 1% compared to control). Therefore, the MIC of tiamulin for this L. intracellularis strain is 8 μg/ml (< 1% compared to control)
