Protocol and results for tests done to detect chicken flu recently at Otago chicken farm.

Stephan Hokke made this Official Information request to Ministry for Primary Industries

The request was partially successful.

From: Stephan Hokke

Dear Ministry for Primary Industries,

I was shocked that there was a positive result in your tests on the chicken farm in Otago. I wish to be sure that your tests are robust and valid and not a random outlier.

Therefore:
1) What report sparked the sending of your team to the chicken farm (copy please)
2) Were the people who took the sample trained in the procedure of getting a sample? Give their name as an identifier such as MPI sampler #001, their qualifications, the chain of custody of the sample from the chicken farm to the testing equipment.
3) How many samples?
4) What method was used to detect the flu? List the machines used, operater's names as an identifier such as MPI tester #001 and their qualifications and experience.
5) How many cycles were used on the sample?
6) How did you match the result to the standard? Please supply the report that the tester provided to you.
7) How can you prove that that standard causes that flu?
8) Please supply all email threads (with names "search and replaced" by an identifier such as emailer#001 etc)

I am sure you have a great team working on this and thus I expect you will supply all the needed confirmation with a minimum of delay that will confirm my confidence that this matter is in good hands.

Yours faithfully,

Stephan Hokke

The cycles was 45 when it should be 40:
https://www.vet.cornell.edu/animal-healt...
I recall that the inventor of PCR (Kary Mullis) indicated 32 cycles was a max which is validated by the UK govt:
https://assets.publishing.service.gov.uk...

The process plateaus at about 32 so why go higher?

Google "maximum cycles for BioRad CFX96 Real-Time PCR Detection System" yeilds

"What is the optimum number of cycles for PCR?
PCR steps of denaturation, annealing, and extension are repeated (or “cycled”) many times to amplify the target DNA. The number of cycles is usually carried out 25–35 times but may vary upon the amount of DNA input and the desired yield of PCR product."
Again: Why 45 cycles?

As to the proof that the standard against which the PCR result is tested to prove it is a flu, they seemed to assume the standard is the cause of the Flu, but did not prove it. This is getting technical so it would be best for a technician to look at this data and see if it makes sense.

Dear Fleur Francois,
Director, Diagnostics, Readiness and Surveillance

Thank you for your thorough response.

The Ct count of 45 caused me to take pause. Perhaps your machines plateau at a higher count as per the UK govt the plateau is at about 32 so why go above that level? I am sending a new request to ascertain that point.

I am not yet convinced that the standard you used is the actual cause of the Avian Flu. Is there a paper that proves this by use of Koch's Postulate?

Yours sincerely,

Stephan Hokke
