Fatal congenital and traumatic cervical spine injuries in a captive newborn plains zebra (Equus quagga)

BACKGROUND: In this report, we describe the clinical, macro-, and microscopic findings of a newborn zebra victim of a fatal trauma and its possible causes are discussed in detail. CASE DESCRIPTION: A plains zebra (Equus quagga) born in a Portuguese zoo was found in hypothermia and unable to get up. The animal was admitted to the hospital 36 hours later and, after the first hour of treatment and no attempts to get up, it began to convulse and died. At necropsy, subdural hematoma and atlantoaxial dislocation were the main findings. CONCLUSION: The inability to pinpoint the exact moment of the lesions’ onset determines the importance of a thorough surveillance of the periparturient period and parturition of captive animals. Furthermore, literature concerning zebras, their reproduction, and neonatal period is scarce, reinforcing the need to report these cases.
