摘要: Abstract Muscular samples from the oesophagus, diaphragm and heart of 101 roe deer (Capreolus capreolus) hunted in Galicia (Northwestern Spain) were examined, by compression method, for presence Sarcocystis spp. infection. The structure cyst wall was examined light (LM) transmission electron microscopy (TEM). overall prevalence infection very high (99%), with a density 404 cysts/sample (SD 812). similar different muscle types (99% diaphragm, 98.9% oesophagus). A significantly higher intensity found (831; SD 1281), followed (197; 190) oesophagus (180; 205). Macrocysts (>1500 μm long) only detected 48.5% deer; their mean size 2055.4 μm 632.46). Cysts localised myocardium shorter (371.5 μm; 160.47) than those (678.2; 546) (973.4 μm; 667.87). By LM, most cysts (98.8%) displayed thin wall, which consistent sp., S. gracilis capreolicanis; 1.2% had thick striated silva. Three morphological distinct sarcocysts observed TEM: unnamed species capreolicanis gracilis. ultrastructure macrocysts This study has revealed that Spanish harbours 4 morphologically sarcocysts; being first record Spain.
