Mastitis is still an important disease causing heavy and irreparable economic losses in the dairy industry. Wedescribe the clinicopathological and microbiological features of an unusual acute septic mastitis caused by P. multocida in a3-year-old dairy goat. At necropsy, the enlargement of the left udder half with hard consistency, the extensive areas ofnecrosis and the accumulations of pus (suppurative exudate) in the cut surface of the affected udder half were observed.Histopathological findings of the affected udder showed severe degeneration and necrosis of the alveolar epithelium and anextensive infiltration of neutrophils within the alveolar lumen. Most of the mammary secretory alveoli were devoid of milkand diffusely filled with basophilic bacterial colonies positively stained by Brown and Brenn method in red color.Microbiological examination of the affected udder revealed P. multocida. It is concluded that P. multocida should beconsidered as an etiological agent of acute septic mastitis in goats.(AU)
