This study was conducted to investigate the similarity between hemagglutination inhibition (HI) test and enzyme-linked immunosorbent assay(ELISA), the HI titer and mean ratio S/P ratio) of avian influenza virus. To perform this study, the 1,457 sera of layers 21 farms in May, July and September, respectively. As a result of HI test, positive rates were 480 to 422 (92.1%) in May, 494 to 394(79.8%) in July and 483 to 402(83.2%) in September, and the mean antibody titer were 4.6, 4.3, 4.0 to 0.3 decreased, respectively. The positive rates by ELISA, 480 to 475(99.0%) in May, 494 to 485(98.2%) in July, 483 to 472(97.7%) in September, and the mean S/P ratio were 2.319, 2.557 and 2.380, respectively. The result of HI test and ELISA positive 480 to 422(92.1%), 475(99.0%), 494 to 394(79.8%), 485(98.2%) and 483 to 402(83.2%), 472(97.7%). Therefore, ELISA was shown more sensitive compare the HI titers.

This survey was performed to investigate avian salmonellosis from broiler farms in Namwon area for 4 years. The whole samples from farms were 541 and chicken samples were 294. Out of 294, 83 cases were identified with avian salmonellosis for 4 years by various serological and biochemical tests. There was no outbreak of pullorum disease, but fowl typhoid occurred in 36 farms. The outbreak of avian salmonellosis occurred continuously regardless of seasons throughout the year. Avian salmonellosis mostly happened within 10 days of age which were 52 cases(63%). The selection of susceptible antibiotics has changed from Quinoline group in 2000 to amoxacillin+clavulanic acid(AmC).
