|The Turid Numbers|
So apparently, the Adesus Wastes were fully consumed by the Turids long ago, and the ones in the Republic were launched as spores from the Wastes. Traveling at about 3% of light speed across the void between the arm and the spur, this means that the first spores were launched towards what is now the Republic some 169 thousand years ago. Before even the creation of Humanity by the Demiurge.
The Far Stars and the other "infected" territories are too far from the Adesus Wastes to have received spores yet. Rather, these have been seeded by Turid-Worshipers (need a name for them), both Human and Colseran that see the bugs as the only truly perfect (and therefore deserving) life-form in the galaxy. Since presumably these are (harking back to the Republic's creation myths) a product of Gaia (this universe) herself, and not Chironic half-breeds born of the meddlings of the Demiurge and the Lord of Chaos.
Which of course puts these groups at direct odds with the Church, much less the rest of thinking humanity. They're a tiny minority compared to the Republic population at large, but even tiny minorities in an empire this big can wield impressive numbers, and it only takes a few thousand crazies to steal and transport a queen egg to an uninfected human world.

The worshipers then take these "wanderers" in, feed them (usually human-sacrificed) food, throw cloaks over them, and try to "help" them spread their perfection by bypassing the Church and Imperial agents that are attempting to hunt them down and stop the Turids' spread.
