Serological study and isolation of Brucellae from dairy cattle were carried out in Kyungbook area of Korea during the period from 1984 to 1985. Biotyping of the isolates was done. Of the 11168 cattle in 2479 herds examined, 27 cattle (0.24%) in the 17 herds (o.69%) were serologically positive for brucellosis. Brucella abortus was recovered from 20 (74.1%) of the 27 infected cattle, and all the strains of the isolates belonged to biotype 1. Of the tissues cultured for brucellae, the supramammary lymph nodes had the highest rate (55.6%) of recovery of brucella organisms
