Sixteen shorthorn cows from Xiazhuang farm were admitted to the Veterinary Teaching Hospital at the College of Animal Science and Veterinary Medicine, Shandong Agricultural University for evaluation of poor appetite, listlessness, fever, tachycardia, tachypnea, lethargy, positive jugular venous pulse and anemia. Blood smear examination and polymerase chain reaction analysis in these cows revealed an infection with Mycoplasma wenyonii.
