This paper deals with the incidence of bovine mastitis for 743 quarters and distribution of Staphylococci for the quarter and 70 bulk milk samples in the northern area of Kyongbuk during the period from Jan to Dec 1984. Isolated Staphylococci were examined for species, subgroups, antibiotic resistance and penicillinase production. A total of 25 (73.5%) of 34 herds, 102 (54.3%) of 188 cows and 208 (30.3%) of 743 quarters were found to be infected with subclinical mastitis. A total of 83 (83.1%) of 102 cows, 94 (45.2%) of 208 mastitic quarters and 55 (78.6%) of 70 bulk milk samples were isolated Staphylococci
