[gecko]Pinworms in Leo Gex

[SamRF2003]

Hi All,
I just got the test results of two fecal samples of two different female adult leos that i got come in today. They have pinworms. Treatment for them will begin tomorrow afternoon by a specialist reptile vet in my area. I have read that in almost all herbivores such as an iguana that pinworms are present, which is known to be helpful for them in breaking down cellulose etc, and that it's not harmful if there isn't a huge abundance of pinworms in them. Therefore I was wondering if the pinworms in my leo gex are detrimental to their health or not. The vet says they should be treated for it, but i'm not sure if they're just money hungry or whether if they're telling me the truth.
A little about my two leos. One's a normal phase female adult leo, the other is a patternless adult female leo.
They have lost a lot of their appetite for a while now, their stools are runny, and they're almost always in their hide caves. One is alone in a 33 gallon tank, and the other in a 10 gallon, all with paper towel as substrate, a couple of hide boxes with one being humid hide, 24hr heat source at 88*F on warm side and 80*F on cool side. Fresh water given daily and their cage cleaned and thoroughly disinfected weekly.
Any help as to whether if pinworms are detrimental to leo gex's health would be great. The vet is also suggesting blood work just incase this is not the cause of the leos prob. Which made me doubt her opinion as to whether if the pinworms are really that bad.
Thanks very much in advance,
-Sam
