A new sampling format for the diagnostics of bovine infectious diseases in dried blood spots by ELISA

Аннотация

The detection of antibodies to bovine infectious diseases (enzootic bovine leucosis, viral diarrhea, and infectious rhinotracheitis) is performed by ELISA in dry whole blood samples obtained on porous membranes using a new sampling format. Several commercial test systems are used to diagnose the infections. The obtained data are compared to the results of the analysis of liquid samples of blood serum. The results of the analysis of dried and liquid samples are in full concordance. The new sampling format makes it possible to avoid using a cold chain for the transportation of samples to diagnostic laboratories and to simplify the storage of these samples.
