Re: Bovine PI3
|From:||Greg Dobbin <dobbin@Upei.CA>|
I realize that the virus is just the instigator and the secondary
bacteria are the real villains, but if a herd was not properly
vaccinated (with the triangle (??) vaccine for PI3, BRSV, and is it
BVD?,) and you determine there was an underlying , primary
infection of PI3; would it not be useful information for deciding to
vaccinate? Most US-Canadian farmers would be up to snuff with
vaccinations, but I am working with a colleague in Northern Mexico
as he attempts to set up an IHC diagnostic service for his area.
I appreciate your input, I am not a Veterinarian, but I worked for 9
years in a vet virology lab here at AVC. Cheers! Greg
