Laboratory tests have pinpointed the equine virus suspected of triggering an outbreak of a respiratory illness that has killed at least 95 captive wild horses in less than a week at a federal corral in Colorado, U.S. government officials said on Thursday.
Results of polymerase chain reaction (PCR) tests from two leading U.S. veterinary diagnostic labs detected the equine influenza virus in nasal and lung tissue samples taken from several horses, the U.S. Bureau of Land Management (BLM) said in a statement.
