[Jacob-list] sore mouth question

[Mary Ellen Hansson]

Hi,
 
I am looking for information regarding sore mouth and TIMING of
infection.
 
We wound up with some variation of this problem a number of years back
from a shearer's tarp that was used here (BAD MISTAKE!!!).  The version
of sore mouth we have doesn't produce those textbook cases, but it
creates a varying number of scabs around the mouths (and occasionally
teats of the moms) of the affected sheep.  I have had 2 different vets
confirm the diagnosis of some sort of sore mouth.  Just as my tapeworms
are not the common variety, I apparently don't happen to have the garden
variety of sore mouth either.
 
Most lambs wind up with a case of it around 4-6 weeks of age.  Some have
one scab and others have 20 or so.  The scabs have come along in the
spring with the lambs and I haven't thought too much about the adults
who are new to the flock that sometimes come down with it in the spring
as well.  
 
Adding lots more sheep this past year has allowed a greater test.  Ewes
that came in May and the ones that came in the fall are dribbling in and
out with a few spots on their mouths this spring starting in January. 
 
QUESTION:  Is there a seasonal variation to this disease?  I have never
seen it written about as such.
