Awesome.
Hi guys,
I LOVED this episode–very easy for the non-virologist to follow, for starters, and fascinating topic too.
Tyler mentioned that one of the Dengues he was discussing (#4?) was of a different clade. I know almost nothing about clades, so I don’t understand how two viruses that share a name can be in different clades? Is it similar to the situation with HepB and HepC where the names are similar, but the viruses are very different?
Thanks as always for a wonderful podcast
In taxonomy a clade is a group consisting of a species and its descendants. Viral clades refer to distinct subgroups of a particular virus, as determined by comparisons of genome sequences. For example, there are four groups of HIV-1, and in group M, there are least nine subtypes or clades. Dengue clades are all dengue virus, but different sequence groups.
Ah, thank you. That makes perfect sense.
