a cylindrical cyst containing parasitic spores,

granuloma
4. Introduce
The article tells about sarcocystis infection
in the meet of Japanese black cattle
The infection has caused eosinophilic myositis
to the meet
Has been seen as partial colour changes in the
meet
Previous studys have showed that
Sarcocystis spp. is often found to be
responsible for eosinophilic myositis
The article handles the closer study of the
damaged meet
5. Macroscopic findings:
Greenish and grayishgreen lesions
Typical from eosinophilic lesions resulted in
cacass condemnation
The larger-sized lesions
6. Histopathological findings:
With inflammatory cell infiltration was
seen granulomas
The capsulated sarcocyst was
surrounded by degenerative eosinophils
and necrotic muscle fibers
Eosinophilic myositis were closely
associated with sarcocystis infection
7. Discussion
Muscle sarcocystis is a parasitic
infection
Herbivores can get it in the feces from on
infected carnivore
This muscular lesion is not always found
in cattle suffering from Sarcocystis spp
- However the histopathological examinations
showed that in that case the myositis was
caused by Sarcocystis spp.
8. Conclusion
The eosinophilic myositis in prime
marbled beef of Japanese black cattle
were resulted from Sarcocystis spp.
