Hi, I am interested in buying a mare with a 2B biopsy. I intend to buy her for showing and breeding. She is a maiden mare but was cultured and found to have e-coli. After this was treated she was biopsied as 2B. As far as i know there is no sign of endometritis, so i assume this is just because of the e-coli. The mare is 7 years old. Problem i have is that over here in England, we don't use this scale to catagorise the uterus very often, so i am not familiar with her chances. Apparently the vet says she has a 70% chance of having a foal. I could probably get the vet report emailed to me.... all these tests were done by someone who was buying her before I saw her, and subsequently pulled out because they already have a problem breeder. Please can someone enlighten me. Obviously with import costs to the UK this is more risky than just buying a horse in your own country etc. Thanks

You need to ask more questions - lots of them! There are inconsistencies in what you have reported that you were told...
If the biopsy scoring system used was the "New Kenney Biopsy Scale" (which seems likely), then a 2B (also written IIB) score carries a likelihood of producing a live foal of between 10 and 50% - a far cry from the 70% you were told!
Additionally, if the mare was identified as having e-coli (a common contaminant of the reproductive tract) - why was there no indication of endometritis? This is suggestive that the culture was of a contaminant, not a problem pathogen. That aspect needs more investigation.
If she had a contaminant in the vagina, why was it there? Was it just a "fluke" or does she have a poor reproductive conformation (i.e. is she "tipped"?)? What is her Caslick's score?
I would strongly encourage you to get a copy of the biopsy score and discuss it with your veterinarian, and perhaps have further evaluations performed depending upon what you see - and consider that the previous buyer pulled out because of not wanting another "problem mare"... so there must be a problem...
