Research on Toll-like receptors (TLR), an important receptor family in immunology, has recently been extended to research connected with animals, such as ruminates (sheep and cattle), swine, dogs, cats and poultry. In ruminates TLR1, 2, 3, 4, 5, 6, 7, 8, 9 and 10 have been demonstrated; in swine, TLR2, 4, 6 and 9; in dogs,TLR2, 4 and 9; in cats TLR1, 2, 3, 4, 5, 6, 7, 8 and 9; whereas in poultry TLR1, 2, 3, 4, 5, 6 and 10 have been noted. On the basis of the homology between TLR in animals and in human and mice and the role and place of occurrence it has been proved that TLR plays a very important role in animals, similar to that in humans and mice.
