However, the cow had escaped its holding pen, and its clinical status was not known.

An 8-year-old 412-kg (906-lb) female dromedary camel was evaluated because of intermittent vaginal discharge of several months’ duration and multiple abortions.

Clinical Findings

During the examination, rectal ultrasonography and vaginoscopy exposed a large extramural mass pushing inward on the uterus. A CBC and serum biochemical profile revealed anemia, neutrophilia, lactic acidosis, and azotemia. Serum progesterone concentration was 0.76 ng/mL, indicative of the presence of a nongravid uterus (serum progesterone concentration is typically < 1 ng/mL in female camels in a non-pregnant reproductive state and peaks at 3 to 5 ng/mL in pregnant camels 1 ). Findings of an abdominal

History

An 18-month-old 55.5-kg (122.0-lb) Dorper ewe with a 2-week history of dyspnea that progressed to open-mouthed breathing was presented to the Texas A&M University Veterinary Medical Teaching Hospital. The referring veterinarian had previously treated the ewe with ceftiofur sodium and flunixin meglumine without improvement in its condition.

Clinical and Gross Findings

At the referral evaluation, the ewe had a high respiratory rate of 60 breaths/min and lung sounds were increased bilaterally, more severely on the right side. Physical examination revealed cervical lymphadenopathy and foamy to mucopurulent discharge from the left nostril that later progressed to bilateral discharge. The face
