Özet:

Biopsy tissues of uterine endometrium were taken from 11 repeat breeding cows and examined histologically. Of the 11 cows 5 (45.45%) showed mild while 6 (54.45%) moderate endometritis. Mild endometritis was characterized by denudation of lining epithelium and moderate infiltration of neutrophils and lymphocytes in the lamina propria. Some of the endometrial glands showed degeneration and necrosis of their epithelial cells. In moderate endometritis, in addition to the above findings there was dense infiltration of lymphocytes and plasma cells in the stratum compactum and early fibroblastic proliferation around some endometrial glands. There was also found periglandular and perivascular leukocytic infiltration. The endometrial glands at some places were distorted and cystic. Uterine mucus was also collected from the repeat breeding cows and the organisms isolated were correlated with the type of endometritis. Mild endometritis was associated with Staphylococcus (19.05%), Bacillus (19.05%), Streptococcus (9.52%), Escherichia (4.76%) and Proteus (4.76%). In moderate endometritis there were found Staphylococcus (14.28%), Streptococcus (14.28%), Bacillus (9.52%) and Corynebacterium (4.76%).
