The present study examined the mammary glands and supramammary lymph nodes of cows with a history of abortion due to Brucella abortus, and presents the histopathological, immunohistochemical, and bacteriological results. The study included 11 Brucella-seropositive cows that aborted during their first gestation. Histopathologically, the mammary glands showed lymphoplasmacytic and histiocytic interstitial mastitis. The lymph nodes had lymphofollicular hyperplasia and medullary plasmacytosis. Immunohistochemistry results showed brucellar antigens, predominantly in the cytoplasm of macrophages, and neutrophils in the intralobular interstitium and periductal stroma in the udders of 3 cows. Desquamated alveolar epithelium also indicated intense immunopositivity. In the lymph nodes, macrophages containing …
