Acute bovine mastitis caused by Klebsiella pneumoniae – case report

Abstract

Th is case report describes the acute mastitis with signs of endotoxemia in the 32-month-old Simmental cow, antimicrobial susceptibility of Klebsiella pneumoniae isolated from a milk sample, and demonstrates the eff ectiveness of the applied therapy. Case presentation included the cowlying syndrome together with the presence of clinical signs of endotoxemia accompanied by milk discoloration and “clots” formation. Bacteriology fi nding of the K. pneumoniae and antibiogram pointed that the isolate was sensitive to ceft riaxone, and trimethoprim/ sulfamethoxazole, while resistant to amoxicillin, gentamicin, ampicillin, ceft iofur, and cephalexin. Th e selection of treatment options came from the availability of an adequate route of administration, urgency for treatment, and lack of time for assessment of other body functions. Th e therapy by ceft riaxone at an intravenous dose rate of 8mg/kg with adequate supportive therapy NSAID, vitamin C, and correction dehydration showed a successful eff ect in life-saving procedures. Th e outcome of K. pneumoniae mastitis with endotoxemia did not aff ect the outcome of pregnancy.
