FX has released a new The Strain teaser trailer, and damn is it creepy.  The series, based off the books by Guillermo del Toro and Chuck Hogan, revolves around a team of scientists who wage war against an ancient strain of virus that confers vampirism, along with those it infects.  Del Toro directed the pilot, but Carlton Cuse (Lost) will be the showrunner.  Every new teaser gets me more excited for this show, and I'm not even a big horror fan.  But I'll watch anything del Toro does, and I'm hoping his first TV series delivers.

Hit the jump to check out the new teaser trailer.  The show stars Corey Stoll, Maestro, Sean Astin, Kevin Durand, Natalie Brown, Jonathan Hyde, Richard Sammel, Robert Maillet, Jack Kesy, Ben Hyland, and Miguel Gomez.  The Strain premieres this July.
