Acute Escherichia coli Mastitis in Dairy Cattle: DiagnosticParameters Associated with Poor Prognosis

[摘要] References(23)Cited-By(2)This study aimed to identify the diagnostic characteristics associated with poorprognosis and mortality in dairy cows with acute clinical Escherichiacoli mastitis. On 17 dairy farms, 24 dairy cows with acute E.coli mastitis that had received therapeutic treatment were categorized into 2groups by outcome: 17 cows that recovered (survivors) and 7 cows that died or wereeuthanized (non-survivors). Two days after onset of acute E. colimastitis, dysstasia was observed in non-survivors, but not in survivors. Compared withsurvivors, significantly increased hematocrit (HCT) values and non-esterified fatty acid(NEFA) concentrations, and significantly decreased antithrombin activity and plateletcounts were found in non-survivors on days 2 and 3 after therapy. Dysstasia, associatedwith decreased antithrombin activity and platelet counts, and with increased HCT and NEFAconcentrations, was considered to be the major prognostic indicator associated with highmortality after therapeutic treatment in acute E. coli mastitis.
