Re: 225G Preliminary Worldwide Tracking & Evaluation
Interesting that this PLoS study used egg passage.
I can't find a way to cut/paste this picture: Figure S6.
If I understand this correctly they innoculated with mixed signals D225X and Q226X (grT and crA).
In the sample taken from the directly innoculated pigs, D225X remained, but 226X reverted to Q226.
When transmitted to other pigs, both reverted to D225 (gat) and Q226 (caa)
So during transmission, it mutated from mixed signals to non-mutated signals?
But then in the lungs, on 1 and 2 days post-infection, it was still D225X and Q226 but on days 4 and 7, it changed to D225G and remained Q226.
Pig 3261 had to be put to death unexpectedly on day 17 due to welfare issues.
