An outbreak of acute eosinophilic myositis attributed to human Sarcocystis parasitism.

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...

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...

Outbreak of Human Infection with Sarcocystis nesbitti, Malaysia, 2012

An outbreak of fever associated with myalgia and myositis occurred in 2012 among 89 of 92 college students and teachers who visited Pangkor Island, Malaysia. The Sarcocystis nesbitti 18S rRNA gene and sarcocysts were obtained from muscle tissues of 2 students. Our findings indicate emergence of S. nesbitti infections in humans in Malaysia.

Eosinophilic Polymyositis in a Mouse

CONTEMPORARY TOPICS © 1998 by the American Association for Laboratory Animal Science 94 The term eosinophilic myositis or polymyositis is used to describe a diverse, heterogeneous group of diseases in human beings and animals. One form of the disease may be associated with parasites that invade muscle tissue, such as Trichinella or Sarcocystis (1–4). In human beings, it has been described as a ...
