Oncoviruses?

On pg 234 of her last book HC has a chart listing parasites and the oncoviruses they carry. They're all abbreviated and it doesn't say what the full name is.

-Dirofilaria carries "FOS"
-F.buski carries "MYC"
-Onchocerca carries "JUN"
-Strongyloides carries "SRC"
-yeast carries "RAS"
-Chickens (and eggs) carry "MYC"
-Ascaris carries "NEU"

There's no glossary at the end of the book or anything. Wondering if Newport or anyone else here have any idea what these are? They don't seem to match to any of the known retroviruses. Tweet
