Seventeen captive Nubian ibex (Capra nubiana) were immobilized for transportation and/or hoof trimming, deworming, and vaccinations. Of these, 11 were immobilized with a combination of butorphanol (0.13±0.03 mg/kg), midazolam (0.13±0.03 mg/kg), and medetomidine (0.13±0.03 mg/kg) (BMM), and 6 were immobilized with a combination of butorphanol (0.11±0.03 mg/kg), azaperone (0.22±0.06 mg/kg), and medetomidine (0.11±0.03 mg/kg) (BAM) by intramuscular injection. Induction and recovery times were recorded. Heart rate, respiratory rate, rectal temperature, blood pressure, and oxygen saturation were measured. The quality of induction, immobilization, and recovery were scored (scale 1-5; 1=poor, 5=excellent). Mean induction time was significantly shorter in the BMM group versus the BAM group (8.8±2.7 and 20.1±7.8 min, respectively). Median induction score and median immobilization score were significantly higher (i.e., better) in the BMM group than the BAM group (5 versus 2.5 and 4 versus 3, respectively). The mean and diastolic blood pressures were significantly higher in the BMM group at the 25-min time point. Atipamezole was administered at the end of procedures, and all ibex recovered smoothly. Mean recovery time was significantly longer in the BMM group versus the BAM group (9.5±4.3 and 3.3±2.2, respectively). In conclusion, at the doses used, the combination of BMM was superior to BAM for short-term immobilization in captive Nubian ibex.

Two wild adult Nubian ibex (Capra nubiana) were captured and admitted to the Hebrew University Veterinary Teaching Hospital with various neurologic signs, including alerted mentation, head tilt, and pathologic nystagmus. The lesion in the central nervous system was localized to the forebrain in one ibex and to the cerebellum of the other. Both ibex's were diagnosed with brain cyst using computed tomography (CT). Craniectomy was performed to remove the cysts, and both animals returned to their natural environment after a rehabilitation period. Parasitologic examination revealed cysts of Taenia multiceps coenurus. This is the first report to describe the neurologic signs, CT findings, surgical procedure, and follow-up postsurgery information in wild Capra nubiana.

A 4-yr-old male bongo antelope (Tragelaphus euryceros) died after an acute clinical course involving a febrile illness, anorexia, lethargy, minor oculonasal discharge, and diarrhea. Histologic lesions were compatible with malignant catarrhal fever (MCF). Polymerase chain reaction (PCR) revealed an amplified region of a herpesviral DNA polymerase gene sequence nearly identical to that of a MCF virus previously identified in Nubian ibex (Capra nubiana). The bongo had been housed across from an exhibit containing Nubian ibex that tested positive for MCF viral antibodies by competitive inhibition enzyme-linked immunosorbent assay. Further testing of the zoo's ibex via PCR also revealed viral DNA sequences nearly identical to those found in the bongo's tissues.
