Toxoplasma gondii, Neospora caninum, Sarcocystis neurona, and Sarcocystis canis-like infections in marine mammals.
Toxoplasma gondii, Neospora caninum, Sarcocystis neurona, and S. canis are related protozoans that can cause mortality in many species of domestic and wild animals. Recently, T. gondii and S. neurona were recognized to cause encephalitis in marine mammals. As yet, there is no report of natural exposure of N. caninum in marine mammals. In the present study, antibodies to T. gondii and N. caninum...
متن کاملSarcocystis mephitisi n. sp. (Protozoa: Sarcocystidae), Sarcocystis neurona-like and Toxoplasma-like infections in striped skunks (Mephitis mephitis).
Two structurally distinct types (A, B) of microscopic sarcocysts were found in muscles of 4 of 5 feral skunks. Type A sarcocysts had sarcocyst walls of up to 6 microm thick. The villar protrusions (Vp) on the sarcocyst wall were up to 5 microm long. The Vp were constricted at the base, expanded in the middle, and had a blunt tip. Numerous microtubules were present in the Vp and in the granular ...
متن کاملA novel Sarcocystis-associated encephalitis and myositis in racing pigeons.
Sarcosporidian cysts in the skeletal muscle of domestic pigeons (Columba livia f. domestica) have previously been attributed to infection with Sarcocystis falcatula, which is shed in the faeces of the opossum (Didelphis virginiana). Here, we describe fatal spontaneous encephalitis and myositis associated with Sarcocystis infections in three flocks of racing pigeons with 47 of 244 animals affect...
متن کاملSarcocystis neurona retinochoroiditis in a sea otter (Enhydra lutris kenyoni).
Sarcocystis neurona is an important cause of fatal disease in sea otters in the USA. Encephalitis is the predominant lesion and parasites are confined to the central nervous system and muscles. Here we report retinochoroiditis in a sea otter (Enhydra lutris kenyoni) found dead on Copalis Beach, WA, USA. Salient lesions were confined to the brain and eye. Multifocal nonsuppurative meningoencepha...
متن کاملExperimental Infection of Horses with Culture-Derived Sarcocystis neurona Merozoites as a Model for Equine Protozoal Myeloencephalitis
A study was designed to develop an experimental model to produce Sarcocystis neurona encephalitis in horses. Sarcocystis neurona, isolated from the spinal cord of an ataxic horse, was placed in continuous culture using bovine turbinate cells, and the cultured S. neurona merozoites were used to infect lymphocytes. A horse that was subsequently experimentally infected with 100,000 of the S. neuro...
