In the picture joint injuries of Avian infectious bronchitis (hidrosalpingitis) and renal injury (by accumulation of uric acid) due to the action of the IB virus (nephropathogenic varieties Massachusets-Holland D212 and D274 former Zanella 2003) can be observed, on renal tissue that causes the failure of the elimination of uric acid and its accumulation in different organs of birds. The effect of renal disease depends on the virulence of the strain and the immune status of birds and visceral consequence may be exacerbated by several factors related to cold stress, diets high in animal protein, poor quality of this protein or calcium / phosphorus diet.
