A sick California sealion（Zalophus californianus） had lived in our zoo for 1 year.On 10 December,2007,the sealion suddenly lost appetite,acted depressed,and suffered swelling of the jaw,tooth inflammation and fever.The index of WBC in peripheral blood was beyond normal,and X-ray examination showed a clear oval transparent margin trim shadow,and a white bone reflection line around the shadow,which we identified as a cyst.Per the result of clinical analyses,laboratory tests and auxiliary examination,we diagnosed that the symptoms were caused by the unilateral mandibular cyst and secondary infection.The major therapeutic measures were the antibacterial to reduce inflammation,rectified water and electrolyte balance,removing heat and toxic material,and root canal therapy.We successfully controlled the inflammation,and the index of WBC in peripheral blood decline to normal range,spirit and appetite and behavior became normal,inflammation in the oral cavity disappeared,and swelling of the jaw gradually diminished.Later nursing and reinforced nutrition promoted absorption of the cyst,which gradually disappeared,and the cyst caused no further harm to the animal.
