Systemic Toxoplasmosis and Gram-Negative Sepsis in a Southern Chamois (Rupicapra Pyrenaica) from the Pyrenees in Northeast Spain

Abstract

Abstract. A 6-year-old, male southern chamois (Rupicapra pyrenaica) had an absence of flight response and was captured by hand in the Catalan Pyrenees in northeast Spain. On clinical examination, the animal was in good body condition, and only atrophy of the right eye was observed. Blood samples were collected and hematologic analysis performed, but no alterations were observed. The animal was sent to a Wildlife Rescue Centre, where it developed chronic wasting and died after 32 days in captivity. At necropsy, the animal was cachectic and had edematous, mottled lungs. Histopathologic examination revealed systemic toxoplasmosis and acute Gram-negative septicemia. The protozoan organisms were identified as Toxoplasma gondii based on immunohistochemistry. An indirect fluorescent antibody test was performed, and the animal was positive with an antibody titer of 1:50.
