FX has released a new trailer for The Strain, and it's the first one that isn't a creepy teaser.  Created and executive produced by Guillermo del Toro, the story 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 co-wrote and directed the pilot and oversaw the writing of the scripts for the first season, but Lost co-showrunner Carlton Cuse acts as the day-to-day showrunner of the series.  This is the first trailer to provide some hints about the plot, but, like the other trailers thus far, shows that TV might have another great horror series on its hands.

Hit the jump to check out The Strain trailer.  The series stars Corey Stoll, Mia Maestro, Sean Astin, Kevin Durand, Natalie Brown, Jonathan Hyde, Richard Sammel, Robert Maillet, Jack Kesy, Ben Hyland, and Miguel Gomez.  The Strain premieres on FX on July 13th.
