There is considerable confusion concerning the structure and synonymity of macroscopic sarcocysts in goats. In the present work, ultrastructural and molecular study on fat and thin macrocysts of Sarcocystis isolated from naturally infected goats were investigated. Two forms of macrocystic sarcocysts were collected from fresh oesophagus, diaphragm, skeletal muscles and heart of slaughtered goats...

The parasites of arctic foxes in the central Canadian Arctic have not been well described. Canada's central Arctic is undergoing dramatic environmental change, which is predicted to cause shifts in parasite and wildlife species distributions, and trophic interactions, requiring that baselines be established to monitor future alterations. This study used conventional, immunological, and molecula...

INTRODUCTION: Road-killed wild animals host zoonotic pathogens such as Toxoplasma gondii, offering a new opportunity for the epidemiological study of these infectious organisms. METHODS This investigation aimed to determine the presence of T. gondii and other apicomplexan parasites in tissue samples of 64 road-killed wild animals, using polymerase chain reaction (PCR). Positive samples were ...

Neospora caninum, a protozoan parasite closely related to Toxoplasma gondii, causes abortion and congenital infection in cattle. To investigate specific methods of antemortem diagnosis, the antibody responses of infected cows were evaluated by immunoblot assay and competitive inhibition enzyme-linked immunosorbent assay (CI-ELISA) by using a monoclonal antibody (MAb), MAb 4A4-2, against N. cani...

Besnoitia besnoiti, an apicomplexan parasite causes economically important disease in cattle in many countries of Africa and Asia is re-emerging in Europe. Serological identification of infected cattle is important because introduction of these animals into naive herds seems to play a major role in the transmission of the parasite. We report new, simplified immunoblot-based serological tests fo...

1. Guinea-pigs, naturally uninfected by sarcosporidia, were infected by feeding them with rat's muscle that was naturally infected by Sarcocystis muris, and by ripe mobile sporozoites from the same source. The infection was not visible grossly, but was detected upon very careful search through many sections of muscle. 2. Sarcosporidia were not found in the guinea-pigs until after an interval of...

A adult female California sea lion (Zalophus californianus) was observed ashore in Marin County, Calif, on January 1, 2010. Assessment of the sea lion the next day indicated it was lethargic and had multiple minor skin wounds. The sea lion was captured and transported to the Marine Mammal Center in Sausalito, Calif, for a health assessment and medical care. Physical examination of the sea lion ...

Acute sarcocystosis was diagnosed in an adult female wild turkey (Meleagris gallopavo) that was collected from Early County (Georgia, USA) in February of 1998. Marked inflammatory lesions were seen in the heart, lung, and liver and were associated with protozoal schizonts and merozoites. The organisms were identified as Sarcocystis sp. (Acomplexa: Sarcocystidae) based on structure and antigenic...
