Septicemic shock secondary to Staphylococcal Osteomyelitis in a ten (10)-month-old Thomson’s Gazelle (Eudorcas thomsonii): a case report

Abstract

Septicemic shock, occurring as a complication of staphylococcal osteomyelitis, caused the fatal outcome in a 10-month-old male Thomson’s gazelle (Eudorcas thomsonii) described in this report. The gazelle was presented with severe, non–weight-bearing lameness of the right forelimb following a recent translocation. Clinical examination revealed a deep, necrotizing, foul-smelling wound with an exposed, fractured ulna. Despite initial antiseptic wound care and supportive therapy, the animal's condition deteriorated rapidly. Hematology indicated severe systemic inflammation with marked leukocytosis, and a wound culture confirmed pure growth of Staphylococcus aureus. The gazelle succumbed to the infection approximately 20 hours after presentation. Necropsy findings documented chronic-active necrotizing osteomyelitis of the right radius and ulna, complicated by fibrinous polyserositis and multi-organ congestion, consistent with septicemic shock. This case highlights the vulnerability of translocated wildlife to opportunistic infections and underscores the challenges associated with managing advanced infections in such compromised patients. The report emphasizes the need for aggressive and timely veterinary intervention, appropriate antimicrobial therapy, and enhanced biosecurity protocols for captive wildlife.
