Pathozone for treatment purposes was administered in two groups of cows with mastitis. The first group consisted of 37 cows suffered from the acute form of the disease and it concerned 74 udder lobuses, the second concerned 27 cows with the signs of the subacute mastitis comprising 28 udder lobuses. There were assayed the kind of secretion, general and local signs at day 0 and 2-4-7 days and 14 days after the treatment. The number of skin lesions and mechanical injuries round the teat canal orifices influenced the development of acute mastitis (at 0,05 < p < 0,10). In the both groups general and organ signs of the disease disappeared though the frequency of the signs at the beginning was different — 59,6% and 2,7% at day 7, and 0% at day 14. The efficacy of Pathozone was well marked in the first 4 days of treatment and at end the effect was similar independently upon the clinical from of the disease. The degree of clinical recoveries was 89,2% in the group of 37 cows and 100% in the second group; in the both groups there was 93,73% of resoveries.
