I found this to be interesting...
"Carotenoids, although not extensively studied, have been reported to be present in a variety of parasitic helminths"..."in Foleyella furcata, a filariid parasite of chameleons"...
"Vitamin A deficiency, unfortunately, is an all too-common occurrence among human popu lations in areas endemic for filariasis".... could depletion of retinol in host tissues be a contributory factor in chameleons vitamin A issues?
