Preliminary studies on the etiology of keratoconjunctivitis in reindeer (Rangifer tarandus tarandus) calves in Alaska.

Keratoconjunctivitis outbreaks occur each summer in reindeer (Rangifer tarandus tarandus) herds in western Alaska, USA. This condition has not been well characterized nor has a definitive primary etiologic agent been identified. We evaluated the eyes of 660 calves near Nome, Alaska, between 29 June and 14 July 2005.
