I agree, I have been studying strongyloides for2 years and talking to vets and strongyloides molt 3 times in their cycle Each cycle they are a different color and interestingly enough the worm molts are made of keritin and chitosan which is plasticy looking same as shrimp skins are made of. Im thinking that EMR/ radiation makes them multiply faster than normally, not to mention steriods do too...so the bodies way of coping with the overabundance of molt skins is by excreting them through the skin,....tbecause they r disseminated, its hard to kill them because they r not in the gut but in the skin and muscles I talked to a vet who said injectable ivermectin with ethanol kills them. I use ivermectin weekly but im thinking they could be resistant so im going to try fen ben.
