The state’s first-ever confirmed case of exotic chewing lice was confirmed Wednesday by Colorado Parks and Wildlife.

Samples from a young male mule deer from the Watkins-area east of Denver were tested locally, then at the National Veterinary Services Laboratory, which confirmed the exotic species of lice (Bovicola tibialis) on March 19.

The deer, which had been reported by an area rancher as being in poor body condition and struggling to survive, was put down by a wildlife officer, officials said.

“Area ranchers and landowners need not be alarmed by this new strain of lice,” said Dr. Karen Fox, wildlife pathologist for Colorado Parks and Wildlife (CPW). “It is not transmissible to humans or domestic animals. Only deer are affected.”

Possible effects of the lice on deer in Colorado are currently unknown. The Washington Department of Fish & Game (WDFW) has dealt with the lice since at least 2005, when the lice were identified on deer that also had hair loss.

CPW is examining deer in Colorado to determine the extent of the disease and possible effects on deer. Anyone who observes sick wildlife is always encouraged to report it to CPW.
