When writs are depleting selenium in mice, is there a food intake problem. GERALD KEUSCH: In the selenium-deficient model, in your initial experiments, did you refeed selenium-deficient animals at some time during the course of the infection and attenuate it. MELINDA BECK: No, we haven't looked at that yet. That is one of those things that we are interested in doing. GERALD KEUSCH: Polucy second part of your presentation was instructive, and you had four separate isolates that you sequenced, and is it my understanding that all of them had undergone all of those write my policy paper. What we think is happening is that the RNA viruses have a high mutation rate because they don't have repair mechanisms.

So, when they replicate, if they make a mistake, they cannot fix it, and what I think is happening is we are driving the evolution of the virus by causing the immune deficiency. So, the viruses replicate fast and they replicate to higher titers, which increases the chances for the mutations to occur, and because of the way we are doing the experiment, we are looking at the time of peak pathology and then taking those viruses out and sequencing them. So, we are seeing the winners of the race, and, I think if we looked earlier, we might see fewer point mutations.

If we look at day wtite, for example, you might see three changes and then maybe at day 6 you see four changes, and m the time when we are looking, it is like, boom, here is the maximum number of write my policy paper that the virus can tolerate. GERALD KEUSCH: Are you erite that the inoculum itself was not mixed inoculum, and you selected rather than. MELINDA BECK: Right, well, I mean with RNA viruses, you have a cloned virus, and a oplicy is never a clone when you are working with RNA viruses, because once I replicate it in cell culture, you are already introducing mutations.

What we are seeing is the consensus sequence of the dominant population.
