The purpose of this study was sero-epidemiological survey of porcine reproductive and respiratory syndrom(PRRS) in Dangjin area. 411 samples from 26 pig farms were analyzed by enzyme linked immunosorbant assay (ELISA). The data indicate that 66% of the pigs and 92% of the farms showed sero-positives to the PRRS virus. Sows showed 58% of sero-positive rate and fattening pigs showed 85% of sero-positive rate. The rate of sero-positive in boars was 63%. No significant regional differences were detected in sero-epidemiological survey.

The purpose of this study was to detect Mycobacterium bovis in cattle(serum, milk, lung, lymph node) by PCR. Nineteen samples from 7 skin test-positive cattle were analyzed. The amplified band of IS6110 by PCR was detected from 2 samples in lung and lymph node. But the sensitivities of the present methods for detecting M bovis in milk and serum are deficient. Because the PCR sensitivity has been shown to he hindered by the method used to isolate the nucleic acid target. PCR-based methods have the potential to be faster, more accurate, and the most efficient means of detecting M bovis. The detection of M bovis by PCR will contribute to the more efficient detection and control of tuberculosis.
