Re: RC: Strangles
I used to board at a facility that had strangles go through the barn about 5
years before I got there. My mare had never been vacinated for strangles,
but was off the track after racing for many years. She never contracted
strangles from this place, and I still don't have her vacinated. Another
horse that moved there shortly after I did had spent it's entire life at one
facility and had contact with only one other horse it's entire life. 2
weeks after it moved there it was a snot factory. The most disgusting
disease I've ever seen. It took about 6 weeks for the disease to complete
resolve. No other horse got sick. I don't know if this means that somehow
my mare has immunity that has lasted a lifetime or if she was just lucky.
