Twenty seven adult horses positive to the agar gel immunodiffusion (AGID ) test for equine infectious anemia (EIA ), but with no history of clinical EIA, were used in transfusion studies to determine whether infectious EIA virus was present in 1 to 5 ml of their blood . Of 27 recipients, 21 (78%) became AGID test positive at an average of 24 days after inoculation. Two horses that were initially negative when screened were retested and found to carry infectious virus in 5-300 ml of whole blood; the other 4 horses were not retested. Horses flies ( Tabanus fuscicostatus Hine ) were unable to transmit EIA vírus from 10 AGID test positive donors with no history of clinical EIA, but virus was transmited from a pony with artificially induced acule EIA and from a horse that had recovered from a clinical attack of EIA 9 months earlier. Histopathologic changes indicative of EIA were noted in all test-positive recipients. The most consistent lesion was paracortical lymphoid hyperplasia in the splenic lymph node. |
