Blood smear taken on day five of hospitalisation of an alpaca diagnosed with acute fasciolosis. Photomicrograph (a) demonstrates decreased erythrocyte density, predominance of eosinophils and immature neutrophils. Other photomicrographs demonstrate close-ups of toxic neutrophils (b,f), eosinophils (c), immature neutrophils (d), monocytes (e) and pleomorphic platelets (g). Images taken using Motic BA410 microscope, Motic Moticam 10 (10.0 mp) camera and Motic Images Pluse 2.0 image processing software, all purchased from Motic Europe, Barcelona, Spain. 100 erythrocytes were measured using the Motic calibration cytometer and their mean size was found to be 6.23 μm with a standard deviation of 0.56 μm and range 4.7 to 7.7 μm. Erythrocyte size was normally distributed. A scale bar in the bottom left of each photomicrograph indicates 10 μm
