[Mycoplasma synoviae-associated amyloid arthropathy in white leghorns: case report]. / Mycoplasma synoviae-geassocieerde gewrichtsamyloïdose bij witte leghorns: casereport.

Under field circumstances amyloid arthropathy was nerve recorded in white layers, while experimentally their brown counterparts were found to be more susceptible to the induction of amyloid arthropathy, although articular amyloid was found in a few white leghorns. In the present manuscript the first field case of amyloid arthropathy in white layers associated with Mycoplasma synoviae is reported. In the same house where the white birds were housed, brown layers were present. The condition was much more severe in the latter chickens. The different susceptibility between both breeds is discussed in view of previously performed research.
