What is it about?

This manuscript summarises the knowledge collected in the literature about AA in chickens during the last twenty years. Highlight concerning the different hypotheses and theories about pathogenesis and transmission of this disease, as well as the differences in susceptibility to AA between brown and white layers, which are frequently unclear and sometime confusing.

Why is it important?

AA compromises the welfare of chickens and has a significant economic impact since the disease affects about 20-30% of all European flocks and it is considered an irreversible disease. AA is the only type of amyloidosis that has been associated with chronic infections induced by Enterococcus (E.) faecalis strains and, therefore, the treatment of this disease has focused to date on the prevention and/or treatment of this infection. Given the intrinsic and acquired resistance of E. faecalis to several antimicrobials and the new regulations to reduce the antibiotic use in animal production, its treatment becomes more complicated, which shows the necessity of a thorough understanding of the risk from field E. faecalis strains in order to develop effective control strategies against AA.
