Re: More H5 and N1 detected in DE
The May 11th detection of H5 and N1 in live birds in Kent County once again led to "no detection" of virus after further testing. The USDA's track record in isolation successes remains intact.

Re: More H5 and N1 detected in DE
And now one of the May 22 Kent ruddy's has also been added for "unable to isolate virus".

It's 5 for 5 ... "no virus isolated" in any of the May samples.

Re: More H5 and N1 detected in DE
Here the latest. Can someone explain how H5 + N1 can be detected but not "virus isolated"

Isolation of the virus (step two confirmation) is performed only at the USDA's National Veterinary Services Lab in Ames, Iowa. It is Biosecure Level 3. It injects the viral samples into embryonted chicken eggs and within seven to ten days can "grow" the virus if it was in large enough quantities and was active. Analysis from the virus cultures (if they were successful in the isolation process) can specifically determine the virus strain (eg H5N1), but only subsequent viral sequencing can spot the poly basic amino acids at the HA clevage site which would represent the high path variety virus.
Having said that, to Dr. Niman's point, one really has to want to find these viruses. It takes diligence because the process is not all that simple and subject to a lot of problems along the way. I would be concerned that an agency whose primary job is to protect the beef and poultry industry might lack a certain level of independence necessary to seek out and find a virus that could cause significant economic disruption to the very food industry that it supports. To my point, please note the following excerpt from the USDA's strategic plans:
"USDA has created a strategic plan to implement its vision. The framework of this plan depends on these key activities: expanding markets for agricultural products and support international economic development, further developing alternative markets for agricultural products and activities, providing financing needed to help expand job opportunities and improve housing, utilities and infrastructure in rural America..."
