I've had these too, but my tests have always been negative for candida. I have taken these in to the lab to be identified 4 times. 3 times the results were "unidentified" and the forth time the lab results said they were 'food' particles. (I don't eat bananas nor do I have the talent to chew my food into symmetrically formed ovoids wrapped in a pattern of 'veins') These were appearing in my stool within a couple days after a full moon, on a regular bases. I took praziquantel and they disappeared for 4 months, but came back a couple of weeks ago. Usually these appear after a high fever and diarrhea. I've wondered before if they are some type of waste build-up that the body tries to excrete by forming cysts/crystals/fatty deposits similar to 'gallstones', but then that does nothing to explain the fine vein-like hairs that are found on these things. I'm sure others have noticed that there seems to be a bit of a morphology that occurs with these. At the first sign of infection they come out with the 'veins' firmly wrapped around a very hard nodule. At this stage you can see a pattern in the 'veins' as two vertical lines, and then attached to these are the numerous horizontal 'veins'. The following day I've noticed the balls appear to be softer/fuzzier and the 'veins' start to separate from the bottom of the main body but are still attached at the top, allowing it to float more (spider-like). After 3 or more days the balls seem to be even more disintegrated and very cotton-like. At this stage a lot of the 'veins' have fallen off and the 'cotton balls' float on their own.
I realize from reading this forum that people seem to think these are somehow related to candida, Ascaris or fasciola but my lab results came out negative for all of these. Not to say that lab results are always accurate, but they may provide some insight to what these things are not--now to learn what these things actually are!
Thanks to everyone who shares their stories and insights on this rather disgusting topic lol, its all very helpful stuff!
