Abstract
The present study shows that the conditions of storage of blood samples and sera have an influence on results obtained with an ELISA test performed to detect antibodies against caprine arthritis encephalitis virus (CAEV) in goats. A storage at room temperature for several weeks or a heating treatment of 56°C for an hour increases the level of optic deviation for sera which contain antibodies as against sera free of antibodies. The authors discuss the role of complement components in such reactions and emphasize the need for caution in interpreting results of antibody tests, especially when comparing the results of archival sera in the absence of information about the condition of storage before freezing.
