Yes, Julius, but you've missed mine as well.
Very true that when there is visible mold there is other stuff is floating around, but there's never been a documented case of any of that causing RI. The very spores floating around tend to kill off the pathogens that are physically small enough to invade the mucus membranes of the respiratory system. We see a lot of digestive and skin problems when those conditions exist, but never a fungal RI.
Not all respiratory symptoms are infectious, sometimes it's just increased mucus flow as a response to surface irritants like dust or spores. That's why I culture everything, then we know what we are dealing with.
Aspergillosis is usually found in cases where no major husbandry problem is noted, and we inspect the home environment of all the animals we rescue and culture the substrate as well as the animal.
