Eosinophilic myositis resulted from Sarcocystis infection in prime marbled beef of Japanese black cattle

Partial changes of color (greenish to brownish) were found in prime marbled beef of Japanese black cattle. The disseminated lesions of the skeletal muscles were histopathologically examined in relation to Sarcocystis infection. The lesions in the muscles showed granulomas with inflammatory cell infiltration. The sarcocysts had a distinct wall, which was radically striated by palisading villar p...

Eosinophilic myositis Associated with Sarcocystis in Sheep

Eosinophilic myositis due to Sarcocystis hominis in a beef cow.

A case of eosinophilic myositis (EM) in an 8-year-old beef cow was investigated. The animal originated from a herd in which a high incidence of the disease had been observed in slaughtered adult females over a period of 2 years. Histologically, the lesions in the muscles were characterized as granulomas with a central core of degenerate eosinophils and remnants of necrotic muscle fibres, surrou...

Allele Frequency Distribution in PNLIP Promoter SNP Is Different between High-Marbled and Low-Marbled Japanese Black Beef Cattle

Marbling defined by the amount and distribution of intramuscular fat is regarded as an economically important trait of beef cattle in Japan. The pancreatic lipase gene (PNLIP) is located within the genomic region of a bovine marbling quantitative trait locus. The rat homologue of PNLIP has been previously shown to be regarded as a possible candidate for the gene responsible for intramuscular fa...

First detection of Sarcocystis hirsuta from cattle in Iran

Although the high infection rate of microscopic sarcocyst occurs in cattle, to the best of our knowledge,there is no report about the identification of macroscopic sarcocyst in Iran. In this work, Sarcosystis hirsutawas first isolated from slaughtered cattle. In a 2-year-old slaughtered cattle, morphological examinationrevealed 3-5 mm in length cysts distributed in different striated muscles, p...
