I found this partial article about adaptations of endosymbionts(one living inside another),and hydra but haven't seen studies of people having infection with them. http://onlinelibrary.wiley.com/doi/10.1111/j.1749-6632.1981.tb54370.x/abstract
Is it too ~preposterous~ to think about? Hmph! It's a big weird world we are living in, especially lately... Many searches result in mostly cartoons and Yugioh or Magic: Gathering cards! Phooey!
The ancients may have paid more attention than we... maybe they had less distractions ?
Check the guy on the left wearing a spotted "skin" that's trying to swallow him like a predator cat would. The spots are like the spots on the hydra he's battling, and the "hands" of the "skin" don't look feline- they look like human! The "tail" sticking out from his belt matches the hydra heads. The club on the ground even looks like ova and testes on a "pregnant" hydra, or possibly one stripped of it's tentacles?
They made stories and art to metaphorically pass the knowledge on to us.
Here's a guy battling a spotted minotaur that's been keeping him stuck inside the labyrinth.
In a previoius post the organism is covered with spots which could be statocysts or a type of bacteria?.

As far as meds, I've been treating with fenbendazole and copper of very small amount(please RESEARCH). Even Hypocrates used copper as medicine!
