In this study isolated Corynebacterium were Corynebacterium striatum 9 (33.3%), Arcanobacterium pyogene 4 (14.8%), Corynebacterium Pseudotuberculosis 2 (7.4%), Corynebacterium ulcerans 5 (18.5%), Corynebacterium bovis 7 (25.9%). The result showed that age, stage of lactation, teat lesion could be a risk factors for presence of bovine mastitis (OR = 1.34, 1.59 and 7.31 respectively).

Key words: Corynebacterium spp., California mastitis test, host determinant, semi-intensive production, Sudan.
