What Is Your Diagnosis?

摘要

A 9-year-old Standardbred mare with intermittent fever, reluctance to move, and prolonged recumbency was evaluated at the Large Animal Hospital at Tufts University. During the 5 days prior to evaluation, the horse had developed a reluctance to walk and attempted to shift its body weight away from the forelimbs and onto the hind limbs. These signs had progressed in severity, despite NSAID administration and application of frog (cuneus ungulae) support pads to the forefeet.Pertinent history included dystocia and caesarian section to remove a dead, full-term fetus 40 days earlier. After surgery, the mare received gentamicin IV, ceftiofur IV, and metronidazole PO for 10 days. After discontinuation of antimicrobial treatment,the mare developed complications associated with the abdominal and uterine incisions, which were treated with several antimicrobial treatment regimens, including enrofloxacin IV, ceftiofur IV, and rifampin PO for 14 days and amikacin IV for 14 days.
