This one is a different, less virulent strain from what they say... completely different company and stock sources... unfortunately even closer to us... this is in the next county over from us... :(
Don:
Thank you Rayvnscroft for the information. So even with the less pathenogenic infection they depopulated the farm. This to me is what I feared. So rather than use this strain to possibly develop a vaccine for commercial flocks.......
Quote from the TN Ag report in the above link,
The primary difference between LPAI and HPAI is mortality rate. A slight change to the viral
structure can make a virus deadly. Avian influenza virus strains often occur naturally in wild
migratory birds without causing illness in those birds. With LPAI, domesticated chickens and
turkeys may show little or no signs of illness. However, HPAI is often fatal for domesticated
poultry.
Jen Mitchell:
Very welcome, Don... wish it was good news to pass around instead of what it is...
What's not making sense to me is, if it's being passed by wildlife/migratory birds, then why is it only commercial flocks that it's been found in so far? Most of those have extremely strict biosecurity and housing requirements, and most from what I understand also don't allow employees to have their own flocks at home too... so how are they getting infected yet not one backyard flock, within or outside the quarantine areas has tested positive?
I dunno, but something just seems off to me...

Don, The first outbreak was found in Lincoln County Tenn. The second outbreak was found in Giles County Tenn. Here is the address of the article that I saw on the second outbreak. http://www.tennessee.gov/agriculture/news/49066

Thanks Gordon. I am finally beginning to see some reports on Google search today.
Jen, It seems to me that with the waterfowl carrying this infection and unharmed, we have to expect that they will always be carriers. They can infect flocks near their migration flyways. But they can also cross infect other birds during their migration movements. I've heard folks concerned about their runs being uncovered thinking that birds flying over would be the problem. But have you ever tried to keep sparrows out of your poultry pens? I know its not that simple, but I seems to me that the commercial industry needs to develop a defense vaccine or breeding a resistant strain of poultry. It has to be cheaper in the long run rather than killing flocks all around the world that become infected. It looks like we are in this for the long run.
