In this article in order to determine the sonographic indexes in bovine clinical mastitis, 30 involved cows with a watery discharge or some flocks in milk, pain, swelling and redness in the udder, and high temperature were selected. Streak canal diameter of the teats, udder cistern epithelium and alveolar parenshyma of milk glands on top of the udder were examined with a 7 MHZ SONO probe in involved quarter as a test, and in the contralateral and normal quarter as a control case. Milk samples obtained from involved quarters for following microbiological evaluations. Finally, the findings with non-normal distributions were compared between control and test groups with the Mann-Withny and Wilcocson-Rank, and data with normal distribution were compared with the Student T test. The diameter of streak canal was (0.82±0.67, (MED=0.8); (0.99±0.13, (MED=. 97) cm, P<0.05), the diameter of udder cistern epithelium was (0.68±0.17, (MED=0.65); (0.68±0.18, (MED=. 65) cm, P>0.05), the diameter of milk gland alveolar parenchyma on top of the udder was (0.98±0.31,(MED=0.9); (0.88±0.3, (MED=. 8) cm, P>0.05) in normal and involved quarters, respectively. Staphylococcus aureus (n= 12), Streptococcus uberis (n=2) and Corinebacterium bovis (n=2) were isolated from the mastitis involved quarters, but their distributions were not statistically different among the various degrees of mastitis. It was concluded that only the diameter of the streak canal increased in mastitis cases. There was no correlation between the kind of isolated bacteria and the site of inflammation in the mastitis cases.
