Abstract

An epizootic of infectious keratoconjunctivitis (IK) was studied opportunistically in free-ranging mule deer (Odocoileus hemionus) from Zion National Park, Utah (USA), from November 1992 to March 1994. Moraxella sp. and Chlamydia sp. were isolated from the conjunctiva of two of seven deer. In addition, Thelazia californiensis occurred on the conjunctivas of six of seven deer. Based on field observations, adults appeared to be affected clinically at a higher incidence during both years as opposed to juveniles. Corneal opacity was the most apparent clinical sign from 1992 to 1993. However, in the following year, blepharospasm and epiphora were noted more often. We were also able to document the clinical recovery of three affected deer. In addition, Moraxella sp. was recovered from the eyes of a clinically unaffected deer 1 year after the epizootic occurred.

摘要

1992年11月至1994年3月期间，在美国犹他州锡安国家公园对自由放养的骡鹿（Odocoileus hemionus）发生的传染性角膜结膜炎（IK） epizootic进行了机会性研究。从七只鹿中的两只的结膜中分离出莫拉菌属（Moraxella sp.）和衣原体属（Chlamydia sp.）。此外，七只鹿中有六只的结膜上出现了加利福尼亚吸吮线虫（Thelazia californiensis）。根据现场观察，与幼年鹿相比，成年鹿在这两年中临床受影响的发生率似乎更高。1992年至1993年，角膜混浊是最明显的临床症状。然而，在接下来的一年中，睑痉挛和流泪更为常见。我们还记录了三只受影响鹿的临床康复情况。此外，在 epizootic发生一年后，从一只临床未受影响的鹿的眼睛中分离出了莫拉菌属。
