Dermatitis fúngica en un pollastre
La pell està incrementada de gruix i les plaques son toves, groguenques al tall i d’aspecte edematós amb la presència de petits nòduls de 2-3 mm de diàmetre. L’estudi histopatològic evidencia lesions inflamatòries de tipus granulomatós. Es realitza una tinció de Grocott que permet identificar la presència d’hifes al centre dels granulomes. S’estableix, per tant, un diagnòstic de dermatitis granulomatosa fúngica.

Comment from Veterinary Pathology group in LinedIn:
D.A.: Have you set up fungal cultures from cases like this, and if so, what did you grow?
Our pathologist answer: Unfortunately we did not process any samples for fungal culture.
It is the first time we diagnose this in a chicken, “organic chicken” pathology is an emerging field here, so we cannot give you previous results. However the lesion type is suggestive of a Zygomicoses.
Comment from Livestock Health group in LinkedIn:
O.P.: My experience includes various predisposing factors especially in tropical poultry production ranging from poor husbandry, unfavorable ambient conditions to complicate initial prediposition to the pathogenic fungi organisms. This is a common complication in broiler chickens raised under poorly ventilated pens with wet floor. In addition, there would be infectious foot-pad dermatitis and chronic gangrenous inflammations of the breast tissues
