Agreed and yes I think it is parasites. The reason i think it's flagellates is the symptoms fit and they all have it. That looks like mucous and/or secondary bacterial infection. Sometimes tapeworms or hookworms can cause bleeding but those don't spread from snake to snake easily or at all while flagellates are highly contagious. Think of this illness as the snake version of dysentery.

They either had it when you got them and so the person you got them from likely has this spreading through his/her collection, or they somehow got it from contaminated water or soil. Being how you feed them worms they could have gotten them from soil / contaminated batch of earthworms. I would reconsider getting worms from any source you have been using and find another or better yet, stop feeding them worms and get them on rodents.
