This photograph is another ox, obviously looking at us and we see a very red, roughened, eroded muzzle, lip and gum. Okay, we need another list, a list of diseases suggested by what we see here.
The lesions present are erosive. What are infections that may cause this? What other causative factors might be involved?
Now, if we look at this photograph, how do we change the list?
Depending on what you had on the list you may not change it at all.
Let's assume you don't change it.
This photograph is from the same ox. You are probably looking at the esophagus here.
Now what would you do with your list? Probably nothing, right?
All possibilities are still in the money.
