Abstract

Infectious keratoconjunctivitis in free-ranging mule deer (Odocoileus hemionus) from Zion National Park, Utah.

Abstract

In an outbreak of infectious keratoconjunctivitis (IK) was studied in free-ranging mule deer from November 1992 to March 1994, Moraxella sp. and Chlamydia sp. were isolated from the conjunctiva of 2 of 7 deer. In addition, Thelazia californiensis occurred on the conjunctivae of 6 of 7 deer. Incidence of IK was higher in adult animals than in juveniles during both years. Corneal opacity was the most apparent clinical sign in 1992 and 1993. In 1994, blepharospasm and epiphora were noted more often. Three affected deer recovered. Moraxella sp. was recovered from the eyes of a clinically unaffected deer 1 year after the outbreak occurred.
