  2. b A strain of L. intracellularis called the PHE/KK421 strain was isolated from a finisher pig with acute proliferative hemorrhagic enteropathy in 2002 [23]. A second strain called PIA/MyCoyL1 was isolated from a grower pig with porcine intestinal adenomatosis in 2010 [25]
  3. c The 5 samples were not contaminated with Mycoplasma and it was presumed that those contaminations were due to other unidentified microorganisms
