Introduction
This article presents the fourth detection of macroscopic cystic lesions due to sarcocystosis in domestic pigs during routine meat inspection worldwide, and the first molecular detection of
Material and Methods
The affected swine showed no clinical symptoms such as weight loss, dermatitis or dyspnoea suggesting sarcocystosis. The presence of grossly visible cyst-like lesions was noticed by veterinary inspectors during post-mortem meat inspection of pig carcasses at a slaughterhouse located in central Poland. Ten rice-grain-shaped white lesions were isolated from the muscle tissue for molecular analysis, and four other macroscopic cyst-like lesions were also isolated for histopathological and microscopy analysis. The molecular characterisation included amplification and sequencing of the cytochrome C oxidase subunit 1 mitochondrial gene.
Results
The cyst-like structures were whitish, calcified, 1 cm long and 3 mm wide. The presence of S.
Conclusion
This study shows that
