Lentivirus infection augments concurrent antigen‐induced arthritis

Abstract
Experimental antigen–induced arthritis was compared in normal goats and goats infected with caprine arthritis‐encephalitis virus. Although acute arthritis was the same in infected and uninfected animals, the disease lasted 16 weeks longer in the caprine arthritis‐encephalitis virus–infected goats. Our findings suggest that the arthritis caused by this virus is due to events other than, or in addition to, the immune reaction to viral antigens.
