Generally speaking fresh pasta has eggs, dried pasta does not. Dried pasta with egg in it is not italian in origin. Sometimes fresh pasta is made with mineral water or wine, this makes a more delicate pasta. You aren't going to see this often though. I have seen a few brands of storebought vegan fresh pasta in the last couple of years. You can certainly make your own fresh pasta at home without eggs, Bryanna Clark Grogan's "Nonna's Italian Kitchen" (which you should all own at least three copies of) has a good recipe. Look for dried pasta which has been extracted through bronze dies, this has nothing to do with veganacity but rather quality. They will have a noticeably textured surface which allows more sauce to be absorbed.
