Now that there is some hope for the drug HUMATIN (= paromomycin - Vet prescribed) in combating Crypto in leopard gecko, I want to share my thoughts on how to further manage this disease organism.
1) Humatin (=paromomycin) 400mg/kg orally for 10 days. Treat ailing
geckos early in the disease process. The sure sign that Crypto is at
hand is that your gecko will regurgitate their skin shed bundle and/or food items undigested. Other symptoms include weight loss, diarrhea, loss of appetite and internal abdominal blackening.
It is my opinion that Crypto is carried by most, if not all, leopard geckos and that symptoms emerge due to stress.
The most common
actions that cause stress are shipping, competition/fighting, improper
cage temperature and over-crowding.
2) Do not over-crowd geckos. Size sort growing young every 10 days
and do not house more than 6 geckos, under 6", in a 16" x 22" x 6" sweater/blanket type plastic storage box. No more than 5 adults in
the same growout space.
3) From hatching, do not keep growout males together past 6".
4) Do not transfer moisture or feces from one cage to another. Wash your hands thoroughly if you come into contact with the water dish or
droppings during regular maintenance. Soak cage boxes and water dishes in 10% ammonia solution for 2-4 hours, rinse, and then let items dry completely for 4-6 hours.
5) I believe that the further a given bloodline is from the "wild caught" line the more susceptible geckos are to Crypto. Make outcross breedings back to wild or different bloodlines every 5 generations to inject vigor into your group and boost their natural immune system.
6) Unless you know the source, quarantine new arrivals for a minimus of 2 months and away from your established geckos. If possible, have your Vet check stool samples from new arrivals or geckos that are losing weight.
These seem to be the best tools to manage Crypto. I believe that implementing such practices will allow anyone to keep this organism
