CASE REPORT: OSTEOPOROSIS AND OSTEOMALACIA WITH MULTIPLE BONE FRACTURES IN A MUNTIACUS REEVESI

摘要

A young female Reeves's muntjac (Muntiacus reevesi) was presented with signs of weakness and inability to stand. Radiographic examination revealed a healed bone fracture in the right radius and ulna. The animal failed to respond to therapy and died two days later. At necropsy, serous atrophy was mainly present in the subcutis of the skull and ventral cervical skin. Muscular atrophy was also evident, especially around the right femur. Multiple bone calluses with newly developed bone fractures were distributed on both sides of the ribs. Microscopically, decreased and irregularly thin bony trabeculae and widened trabeculae with excess unminer-alized osteoid were observed in both femurs. Multiple sarcocysts were incidentally noted in the right femoral and longissimus dorsi muscles. It was concluded that M. reevesi in the present case appeared to have suffered from osteoporosis and osteomalacia with multiple bone fractures.
