Now this is interesting, and something that we've discussed before. We haven't found any real answers, but here's what happened with Dirt:
After about a month or so of treatment, she was getting progressively better. Her draining lesion was clearing up, she was breathing better, starting to eat again, all that. But she began getting little black lesions about the size of a pencil eraser around her paws and ankles where there hadn't been anything before.
Of course, we were continuing Itra treatment anyway, but we used an OTC antifungal medication on them and they went away pretty quickly.
We postulated that maybe the fungus was "running" to the surface, which might sound silly. But after hearing others say that they got even bigger lumps, lesions, and even huge pustules that swelled up and burst (gross, I know) after being on treatment for a couple of months, etc. we thought maybe there was something to it after all - fungus looking for a way out. I'd really love to see more studies or monitoring of the disease/treatment process.
But as far as research and information, as anyone here has seen, - this is it for experience, right here, Lisa's forum. We appear to be the front line.
Perhaps Blasto is not "sexy" enough to warrant more in-depth studies.
