Osteomyelitis and periosteal reaction in a red brocket deer (Mazama americana)

Anamnesis and treatment approach: a female red brocket deer (Mazama americana, Erxleben 1777) presented a post-traumatic abscess in the left-carpometacarpal joint. The deer was treated with enrofloxacin (5 mg/kg) and ivermectin (0.2 mg/kg) with no response. The animal underwent two surgical procedures to remove purulent material and perform adequate antisepsis as well as several antimicrobial therapies, with satisfactory results in a period of 68 days. Clinical and laboratory findings: according to the radiological and laboratory tests the animal developed a metacarpal bone osteomyelitis with periosteal reaction due to a beta-hemolytic Streptococcus abscess. Conclusion: to our knowledge, this is the first report of medical procedures in this species. The most relevant findings and treatment schedule are discussed.
