Comparative effectiveness of diagnostic methods for bovine leukemia

The scientific study was conducted to compare the effectiveness of diagnostic methods for bovine leukemia. Serological methods (RID and ELISA) and polymerase chain reaction (PCR) were investigated on over 300 blood serum samples from cows. The results showed that the effectiveness of ELISA and PCR in detecting infected animals was similar and significantly higher than RID. PCR also detected the env virus in samples that were negative in serological methods. These results emphasize the importance of using PCR in diagnosing bovine leukemia, especially in troubled farms. However, serological methods remain suitable for large-scale studies. Overall, studying these methods is important for more accurately detecting infection and effectively combating the disease.
