If there was an award for most teasers for television series yet to debut, it'd probably go to FX's The Strain. The horror series was ordered in November, with the first teaser hitting in December. Since then a variety of short clips have been released, teasing elements of the mythos created in the novels by Guillermo del Toro and Chuck Hogan.

Collider compiled the three latest teasers, along with some stills from the series, which premieres July 13. The videos showcase the worm-like creatures that spread the vampirism virus, while the photos feature stars Corey Stoll, Mia Maestro and Sean Astin.

The Strain is a high concept thriller from Academy Award® nominated Filmmaker Guillermo del Toro, author Chuck Hogan and writer/producer Carlton Cuse, which is based on the best-selling vampire novel trilogy of the same title written by del Toro and Hogan. It tells the story of “Dr. Ephraim Goodweather,” the head of the Center for Disease Control Canary Team in New York City. He and his team are called upon to investigate a mysterious viral outbreak with hallmarks of an ancient and evil strain of vampirism. As the strain spreads, Eph, his team, and an assembly of everyday New Yorkers, wage war for the fate of humanity itself.
