Just relaying info. The articles refer to "long time" would be during winter months as that is when these infections are most prevalent and birds getting reinfected ...but since his is he first time I've owned chickens I'm definitely not an expert in the subject. "fomites" which are inanimate objects so structures would be waterers, feeders etc removing them and cleaning them. (Guess I should be more specific) that's why I linked the articles but maybe I read it wrong-
Been wrong before so... anyway just wanted to help with info sometimes takes lots of time to sift through all the articles, hope they were of some help.
Sorry. You are incorrect about mycoplasmas existing in soil and structures for a VERY LONG time. Mycoplasmas have no cell walls and that makes them very fragile, they can only exist in the environment about 3 days. Disinfecting and sunlight will easily kill them. Structures DO NOT have to be removed. However, I recommend that if mycoplasmas are present in a flock, infected birds should be culled and everything should be cleaned and disinfected, strict biosecurity procedures maintained. Personally, I would wait at least a few months before repopulating (without testing) due to the fact another disease(s) could be involved as well even though repopulation can be sooner with mycoplasmas. Also, if birds are infected and are survivors of the disease, then yes, it is true that stress can cause symptoms to reoccur. I agree that there could be other diseases involved. A good example would be coryza and mycoplasma gallisepticum having almost the same symptoms and birds can have both diseases (or more diseases) at the same time. If this were the case, I'd be concerned about incubation and course times of ALL diseases involved. I would cull them all if they were my birds.
The OP isnt sure if it is a mycoplasma disease she's dealing with. It'll depend upon the results of the bloodwork. If it's strictly a mycoplasma disease, denagard will treat it. She has made it clear that she will not cull.
