The Infection Test Facility and the Black Nanopod Facility were removed from the game shortly after the Infected Outbreak event ended. Right now, there's no way to build either of them, but players who still have them from the event can still use them. It's entirely possible that they'll re-add the buildings if there's ever another Infected event, though.
