Mycoplasma:  (Myco, Mycoplasma bovis)


(Myco, Mycoplasma bovis)

Mycoplasma is a type of bacterium that has recently become infamous in the deer industry. This bacterium can cause several problems, but the most concerning is pneumonia. It is contagious and easily spread from deer to deer. One scary aspect to this disease is that it can take several days from infection to the onset of signs. That means an infected deer can be brought onto a farm and spread this disease even though it appears healthy.

Mycoplasma bovis diagnosis is difficult because it takes a special process to culture this bacterium. Diagnosis is usually made from samples taken at necropsy. There is no evidence that the available vaccines provide adequate protection.
