[Jacob-list] West Nile & Sheep

[Karen]

    Does any one know if sheep can get West Nile and what the symptoms 
are?  My sheep are sick.  Runny noses, coughs, some pretty sever 
congestion.  I have wormed, LA 200 shots, tetracycline in the water, 
myocine(?) in the grain,  I have even started some of them on 
Benatrayl.  I can get them better, but as soon as the meds wear off, the 
flock is sick again.  So I am thinking this is viral,  maybe West Nile.  
We live in a mosquito infested area and have had two humans locally die 
this year from West Nile.  Also I have had several people around this 
area tell me, they have had animals die unexpectedly on them and not 
know why.
    Two of my sheep, have become so congested, that they could not 
breath thru their nose and started foaming at the mouth.  Any suggestions??
Thanks Karen
