An isolated antigen against a Mycoplasma , prepared by a method including providing a sample of a Mycoplasma and an antibody probe, probing the Mycoplasma sample with the antibody probe to detect at least one antigen, and isolating the antigen detected. The antibody probe includes at least one antibody against the Mycoplasma that is produced by a method including (a) providing a biological sample taken a short time after an immune animal has been challenged with a Mycoplasma or Mycoplasma extract taken from the infection site or an area of a lesion or an area close to the infection site or lesion; (b) isolating cells from the biological sample; (c) culturing the cells in vitro in a suitable culture medium; and (d) harvesting antibodies produced from the cell. |
