The study included 82 clinical mastitic cows (328 quarters) in two dairy cattle stations, 15 cows in the first station in Baghdad and 67 cows in the second station in Babel, Clinical inspection was conducted on cows and it’s udder, milk samples were collected under sterile condition and subjected for physical, chemical & bacteriological examination with antibiotic sensitivity test of the isolated pathogens. The mastitic cows in each station were divided into two groups, the 1st (Treated group) in which cows treated by us and the 2nd (control group) in which cows were treated by the staff of station. After treatment all cows were examined clinically and bacteriologly four times (once 10 days). Swaps from milker’s hands and milking machine were also taken. The results revealed that out of 328examined quarters, 212 quarters were infected (55 quarter in the 1st station and 157 quarter in the 2nd station). The acute form of mastitis represent high percent and the occurance of the disease increased with the advance age. The hind quarters were more frequently affected than fore ones. Staph.aureus was the only isolate from the 1st station, while 14 type of bacteria was isolated from the 2nd station .Staph. aureus & Staph.epidermidis were isolated from milker’s hand,where as Bacillus cereus, Klebsiella pneumoniae . & Pseudomonas aeruginosa & Pasteurella spp. were isolated from teat cups.
