Aspergillosis (Brooder pneumonia)
Aspergillus fumigatus, A. flavus, and A. niger. Fungus has conidiophores which are smooth, colorless to light green near the vesicle. The conidiophore enlarges to form a flask‑shaped vesicle. Conidiophore contains globase vesicles, phialides and radiate chains of conidia. Fungi can be isolated on artificial media and are inhibited by some antibiotics.
