i bought a few ball pythons off of craigslist and one had something similar to that but not quite as bad. the guy i got them off of had used that same carefresh bedding. i put her on some newspaper and used a chlorhexidine solution a couple times and with in one shed she was fine. but like i said it wasn't near as bad as the one in the picture.

Keep her clean and dry and keep up the ointment. You could also give her a soak in betadine in water, mix it to look like weak tea, soak for 20-30 mins then rinse. If it doesn't clear up with her next shed or gets worse then try a vet.

Ball pythons don't need as much humidity as we used to think. Being to damp can lead to respiratory issues and fungal/rot type issues. Keep her clean and dry and give her a soak once in a while and mist if she is having a rough shed. 

I have always had sucess with cholorhexadine solution. Whether I let them soak (head out, tho) or used paper towels to swab them with, that is my go to cure. It has never failed me. But yes, I bleach cages, put on newspaper or paper towels, but a tiny bowl of water, just for drinking, and start the chlorohex soaks EVERY DAY until the next shed. Once the snake sheds I kinda just touch and go from there. Chlorohex has never failed me.

+1 shellboa, a little betadine soak and being kept clean until she sheds once or twice should do it.

Yes, it's a little bit of scale rot, but it's not really that bad.  You're not a bad snake lady until you don't notice the rot happening to the point of it becoming a serious issue. 

What kind of bedding are you using?  Can you load up a picture of what the cage looks like?  I'm trying to think about what could be going on that would cause the snake to sit in a soggy enough part of the cage and develop that.  How are you heating her up and what's the ambient temp in the part of the house she's in? 

I've been using Fluker's aspen bedding, sometimes colored naturally sometimes normal. I was using ZooMed Repti-Bark before that upon someone's recommendation who keeps herps. I remember now that I thought the red dust from it was staining or coloring a few of her belly scales here and there, but that could have very well been where it started.

Here's the cage: http://img27.imageshack.us/img27/4660/img0986mz.jpg

And here's about how big of a water dish she's getting for right now: http://img576.imageshack.us/img576/2960/img0987mt.jpg

She normally has a big one she could fit 2/3 of her body into. Also, this obviously isn't her normal setup. The shoebox is replacing a half-log hide that I was told to throw away. Since I just set that up today that isn't the normal temp she's at. Warm side is around 84, hotspot on top of the warm hide is around 89 and the cool side is 75. During the day, of course. At night she's still at 80 on the warm side and low 70 on the cool side.

I have both the lamp and a UTH. The room is typically 70 degrees that she's in.

I could tell from changing her water every morning that she would drag bedding into the water bowl so she does lay in it, and maybe she spilled water into the bedding early on in the night and it soaked to the bottom by morning so I didn't feel any moisture the next day. She might do it every night.

But for now she's got the papertowels. Is it safe to use the combination of Betadine or Chlorhexadine with Triple antibiotic stuff?

Honestly I doubt you even need to put antibiotics on it at this point, just do the betadine for a while.  Maybe increase heat a little bit but otherwise she looks great so just let her shed and she'll probably go back to looking totally normal. 

Personally I prefer using orchid bark or cypress, as they hold more moisture in a better way for me.  My snakes manage to douse their cages for the most part, and even with relatively soggy bedding they don't have scale problems or shedding problems. 

I just wanted to do an update. As of today, Imogen is 100% better and spotless on her belly. The betadine and substrate change did wonders and I know what to do next time. Thanks for everyone's help. I am super happy. :]
