Plain-English summary
A horse was tested for equine infectious anemia, a viral disease, and the results were unclear over a three-year period. The horse did not have a fever, and the virus was only found in one out of six attempts to infect other horses. The test results showed a temporary increase in reaction after the virus was detected. Even though most attempts to transmit the virus were unsuccessful, the one successful attempt confirmed that the horse was indeed infected.
Abstract
A horse whose serum reacted equivocally in the agar gel immunodiffusion (AGID) test for equine infectious anemia was studied over a 3-year period. The horse remained afebrile and virus was detected in only 1 of 6 horse inoculation tests. The intensity of AGID test reactions increased temporarily following this evidence for virus. Although the AGID test reaction was equivocal and 5 of the 6 transmission attempts failed, the 1 successful transmission proved the horse was infected.
