Department of Medical Parasitology and Mycology, School of Public Health, Tehran University of Medical Sciences, Tehran, Iran.

is a genus of eucoccidian parasites, which globally infects humans and various animals. In addition to economic losses in livestock industries, the parasite is a zoonosis that infects humans through contaminated beef and pork with the parasite sarcocysts. Therefore, this study was carried out to assess contamination in beef and industrial raw beef burger samples from butcheries and retail stores in Tehran, Iran. Read More

Department of Animal Health, Veterinary Faculty, Complutense University of Madrid, Avenida de Puerta de Hierro s/n, 28040, Madrid, Spain.

The major aim of the present study was to determine by molecular methods whether the wide and narrow types of macroscopic sarcocysts in Spanish sheep belonged to different species, that is, Sarcocystis gigantea and Sarcocystis medusiformis, respectively. Additionally, we wanted to identify and characterize molecularly the species forming microscopic sarcocysts and determine the phylogenetic placement of all species found. Portions of the oesophagus, diaphragm and hind legs containing macroscopic sarcocysts were collected from slaughtered culled ewes at an abattoir in the Province of Madrid, Central Spain, but both macroscopic and microscopic sarcocysts were isolated for molecular examination.

First Case Report of Possible Sarcocystis truncata-induced Food Poisoning in Venison.

Intern Med 2019 Sep 22;58(18):2727-2730. Epub 2019 May 22.

National Institute of Health Science, Japan.

Along with the increase in consumption of raw animal meat, the prevalence of food poisoning is increasing. A 67-year-old Japanese man had eaten raw venison 4 hours prior to the beginning of vomiting. Many white cysts were discovered in the venison, with numerous bradyzoites being detected after the cysts were punctured. Read More

Molecular Characterization of Species Isolated from Sheep and Goats in Riyadh, Saudi Arabia.

Animals (Basel) 2019 May 21;9(5). Epub 2019 May 21.

Zoology Department, Faculty of Science, King Saud University, Riyadh 11451, Saudi Arabia.

Sarcocystosis is induced by species of , which is an intracellular protozoan parasite in the phylum Apicomplexa. The diversity and importance of species in sheep and goats in Saudi Arabia are poorly understood. In this study, the tongue, esophagus, heart, diaphragm, and skeletal muscles were collected from 230 sheep and 84 goats, and the tissues were examined for the presence of species by macroscopic examination and light microscopy.

Spatial Analysis of a Cat-Borne Disease Reveals That Soil pH and Clay Content Are Risk Factors for Sarcocystosis in Sheep.

Front Vet Sci 2019 24;6:127. Epub 2019 Apr 24.

School of Animal and Veterinary Sciences, The University of Adelaide, Roseworthy, SA, Australia.

Cat-borne parasites and their associated diseases have substantial impacts on human, livestock, and wildlife health worldwide. Despite this, large and detailed datasets that allow researchers to study broad-scale trends in the ecology of cat-borne diseases are either difficult to obtain or non-existent. One condition that is easily detected at slaughter is macroscopic sarcocystosis, a cat-borne parasitosis of sheep (). Read More

-Induced Myeloencephalitis Relapse Following Anticoccidial Treatment.

J Parasitol 2019 04;105(2):371-378

is a ubiquitous parasite in the eastern United States, which is the principal causative agent in the neurologic disorder equine protozoal myeloencephalitis (EPM). While much is known about this protozoa's life cycle in its natural host, the opossum (), little is known of how it acts in the aberrant equine host, which displays a high incidence of exposure with a relatively low rate of morbidity. For this study, we employed the popular interferon gamma knockout mouse model to determine the potential for recrudescence of infection after treatment with the anticoccidial drug diclazuril.

Genetic variability within isolates of Sarcocystis species infecting sheep from Egypt.

Vet Parasitol Reg Stud Reports 2018 08 7;13:193-197. Epub 2018 Jul 7.

Parasitology Department, Faculty of Veterinary Medicine, Mansoura University, Mansoura 35516, Egypt.

In order to explain the exact role of sarcocystosis, principally Sarcocystis tenella, in losses of the Egyptian sheep industry, a precise confirmation about the existence of different Sarcocystis species infecting that economically important animal is needed. Therefore, this work aimed to molecularly identify, as well as illustrate the genetic variability within isolates of Sarcocystis spp. infecting sheep from Egypt. Read More

Molecular differentiation of five Sarcocystis species in sika deer (Cervus nippon centralis) in Japan based on mitochondrial cytochrome c oxidase subunit I gene (cox1) sequences.

Parasitol Res 2019 Jun 18;118(6):1975-1979. Epub 2019 Apr 18.

Department of Food Safety and Infection Biology, Faculty of Veterinary Medicine, Norwegian University of Life Sciences, P.O. Box 369 Sentrum, 0102, Oslo, Norway.

Several surveys of Sarcocystis infection in sika deer in Japan have shown a high prevalence, but the identification has been unclear because molecular data have been lacking or have been limited to 18S ribosomal RNA gene sequences. Thus, in our previous study based on such sequences, some Sarcocystis isolates from sika deer were not clearly separated from other species in the phylogenetic analysis. In the present study, we therefore characterized sarcocyst isolates from sika deer (Cervus nippon centralis) at the mitochondrial cytochrome c oxidase subunit I gene (cox1). Read More

3 The Marine Mammal Center, Sausalito, CA, USA.

A myositis syndrome has been recognized for more than a decade in California sea lions (CSLs; ) but a detailed description of the lesions and potential causes of this condition is lacking. The tissues of 136 stranded CSLs with rhabdomyositis were examined. Rhabdomyositis was considered incidental in 67% (91/136) of the CSLs, and a factor contributing to the animal stranding (significant rhabdomyositis) in 33% (45/136). Read More
