The subacute form it is identified by the difficulty encountered by the birds to move in due to tenosynovitis, advancing slowly, with an unsteady gait, and showing large variability in function of the severity in each specific case.

In the case of the cocks, their ability to mate properly with the chickens is compromised, which leads to a decrease in fertility.

Usually, the birds affected experience a progressive decrease in weight by not being able to move normally, beginning to be observed in deaths between ten and fifteen days.

The chronic form occurs sporadically and almost always in adult birds, beginning with the formation of a cushion plant that, in its chronic evolution, develops into a bag of considerable size in the base of the foot.

On certain occasions, this bag planting can necrosarse, causing a process of gangrene foot due to the action of other bodies.
