A Case Report of Spontaneous Polyarthritis in Cynomolgus Monkeys

: Veterinary x-ray photography and examinations of synovial fluid, blood and urine were conducted on a Cynomolgus Monkey from China (5 years old) which exhibited macroscopically visible systemic joint swelling after the quarantine period. The presence of inflammatory cells in the synovial fluid obtained by arthrocentesis, high counts of neutrophils, monocytes and large unstained cells and the elevated serum CRP level suggested that the lesions in this animal were due to polyarthritis.
