Presumptive Babesia ovis infection in a spanish ibex (Capra pyrenaica).
On December 29 1995, a 13-year old, male Spanish ibex was easily captured by hand, with depression, weakness and severe tick infestation, mainly in the periocular and auricular regions. Blood and serum samples were collected and haematological analysis and serum iron levels were determined. Red blood cell count, haematocrit, haemoglobin concentration and mean corpuscular haemoglobin concentration (MCHC) were decreased and mean corpuscular volume (MCV) increased (macrocytic-hypochromic anemia). Serum iron and transferrin saturation were decreased and total and unbound iron-binding capacity were increased. Piroplasms were observed within parasitized erythrocytes and presumptively identified as Babesia spp. Ticks were identified exclusively as Ripicephalus bursa. The animal was treated with imidocarb but died after 15 days of capture. Histopathological examination revealed congestion of pulmonary capillaries and spleen, glomerulonephritis, hemoglobinuric nephrosis and generalized hemosiderosis. An indirect fluorescent antibody test was performed using a Babesia ovis isolate of ovine origin as antigen and the animal was positive with a titre of 1:640.
