opportunist
aspergillosis is most common in which species
poultry
which part of body do aspergillus affect
lungs(pneumonia) blood vessels(mycelial emboli)
toxins produced by aspergillus
alfatoxins
alfatoxins cause disease called
alfatoxicosis(myco-toxicosis)
aspergillosis in poultry is known as
brooder pneumonia
aspergillosis commonly occurs in _______ in horses
guttural pouch(recurrent epistaxis)
M. lesions of aspergillosis
