Another way to explain it is that the idea of hollows being poisonous to quincys didn't came yet, so no one didn't actually thought a lot of Ayon being absorbed by Quilge Opie. Like when Sora/Acidwire ripped his mask off and didn't became an Arrancar because it was on the 5 episode and in that moment not even the idea of the Zanpakuto Spirit came.
