Clinical mastitis and distribution of pathogens in dairy cows was observed in 100 cows at ASAS dairy farm, Iringa, Tanzania. It was found that 8 animals (8%) had clinical mastitis and 26 cows tested positive (26%) with indicator paper for udder control (Bovi - Vet Derunark). Out of the 26 milk samples cultured for bacteria isolation 15 samples showed bacteria growth. The most isolates were Staphylococcus aureus (53.3%), Streptococcus agalactiae (13.3%), Escherichia coli (13.3%), Candida albicans (13.3%) and Proteus vulgaris (6.7%). Acute mastitis was observed in cows where Escherichia coli was isolated, mild insidious mastitis in cases where Staphylococcus aureus was isolated, while in chronic cases the most isolate was Candida albicans .
