Detection of in blood of llama using a duplex semi-nested PCR assay and its association with cyst infestation.

Heliyon 2018 Nov 13;4(11):e00928. Epub 2018 Nov 13.

Instituto de Patobiología Veterinaria, Centro de Investigaciones en Ciencias Veterinarias y Agronómicas (CICVyA), Instituto Nacional de Tecnología Agropecuaria (INTA), Argentina.

The protozoon is the causative agent of South American camelid (SAC) sarcocystosis. Infections are characterized by the presence of cysts in muscles which are in size and appearance similar to rice grains. As consumption of insufficiently cooked infected meat produces gastroenteritis, cyst-containing SAC meat is confiscated by sanitary authorities or depreciated with serious economic consequences for SAC breeders.

Nature Research Centre, Akademijos 2, LT-08412, Vilnius, Lithuania.

Having examined 19 great cormorants (Phalacrocorax carbo) hunted in Lithuania, sarcocysts were found in the muscles of two birds. Sarcocysts detected were examined using light microscopy (LM), transmission electron microscopy (TEM), and 18S rDNA, 28S rDNA, ITS1, cox1, and rpoB sequence comparison. Based on the molecular analysis, mainly of the ITS1 region, sarcocysts were identified as Sarcocystis halieti. Read More

Department of Clinical Studies, New Bolton Center, School of Veterinary Medicine, University of Pennsylvania, Kennett Square, Pennsylvania.

Background: Infection by 2 or more protozoa is linked with increased severity of disease in marine mammals with protozoan encephalitis.

Hypothesis/objectives: To assess whether horses with equine protozoal myeloencephalitis (EPM) caused by Sarcocystis neurona also have evidence of infection with Neospora hughesi or Toxoplasma gondii. We hypothesized that horses with EPM would be more likely than horses with cervical vertebral stenotic myelopathy (CVSM) to be positive for antibodies to multiple protozoan parasites. Read More

Members of the genus Sarcocystis (Apicomplexa: Sarcocystidae) are intracellular protozoan parasites that infect a wide range of domestic and wild animals, resulting in economic losses in production animals worldwide. Sarcocystis spp. have indirect life-cycles where canids and felids serve as main definitive hosts while a range of domestic and wild animals serve as intermediate hosts, including South American camelids (SACs) such as alpacas, llamas and guanacos.

United States Department of Agriculture, Agricultural Research Service, Animal Parasitic Diseases Laboratory, Beltsville Agricultural Research Center, Beltsville, MD, 20705-2350, USA.

Rodents are intermediate hosts for many species of Sarcocystis. Little is known of Sarcocystis cymruensis that uses the Brown rat (Rattus norvegicus) as intermediate hosts and the domestic cat (Felis catus) as experimental definitive host. Here, we identified and described Sarcocystis cymruensis in naturally infected R. Read More

Department of Pathology and Parasitology, State Veterinary Institute Prague, Sídlištní 136/24, 165 00, Prague 6 - Lysolaje, Czech Republic.

Muscular sarcosporidial infections by Sarcocystis lutrae (Apicomplexa: Sarcocystidae) from the otter (Lutra lutra) and badger (Meles meles) (Carnivora: Mustelidae) were found in the Czech Republic. As part of a diversity evaluation of Sarcocystis in wild carnivores during 2016-2017, samples of diaphragm, tongue and hind-limb muscles were collected from nine districts, examined by compression and characterized molecularly. Cyst walls were thin, with no visible protrusions, and histological sections of infected muscle tissue showed no host responses. Read More

MORTALITY TRENDS IN NORTHERN SEA OTTERS ( ENHYDRA LUTRIS KENYONI) COLLECTED FROM THE COASTS OF WASHINGTON AND OREGON, USA (2002-15).

J Wildl Dis 2018 04 20;54(2):238-247. Epub 2017 Dec 20.

1   US Geological Survey-National Wildlife Health Center, 6006 Schroeder Road, Madison, Wisconsin 53711, USA.

During 2002-15 we examined the causes of mortality in a population of northern sea otters ( Enhydra lutris kenyoni). Beachcast sea otters were collected primarily from the US coast of Washington. Although there are no permanent sea otter residents in Oregon, several beachcast otters were collected from the Oregon coast. Read More

Vet Parasitol 2017 Nov 9;247:80-84. Epub 2017 Oct 9.

Molecular Parasitology Section, Laboratory of Parasitic Diseases, National Institute of Allergy and Infectious Diseases, National Institutes of Health, Bethesda, MD 20892, USA.

The protozoan parasite Sarcocystis neurona is an important cause of disease in horses (equine protozoal myeloencephalitis, EPM) and marine mammals. Isolated reports of clinical EPM-like disease have been documented in a zebra, raccoon, domestic cat, domestic dog, ferret, skunk, mink, lynx, red panda and fisher. The predominant disease is encephalomyelitis associated with schizonts in neural tissues. Read More

Testing the Sarcocystis neurona vaccine using an equine protozoal myeloencephalitis challenge model.

Vet Parasitol 2017 Nov 13;247:37-41. Epub 2017 Sep 13.

Department of Veterinary Preventive Medicine, College of Veterinary Medicine, The Ohio State University, 1920 Coffey Road, Columbus, OH, 43210, United States.

Equine protozoal myeloencephalitis (EPM) is an important equine neurologic disorder, and treatments for the disease are often unrewarding. Prevention of the disease is the most important aspect for EPM, and a killed vaccine was previously developed for just that purpose. Evaluation of the vaccine had been hampered by lack of post vaccination challenge. Read More

Small sarcocysts can be a feature of experimental infections with Sarcocystis neurona merozoites.

Vet Parasitol 2017 Oct 26;245:116-118. Epub 2017 Aug 26.

Rood & Riddle Equine Hospital, Lexington, KY, USA.

Several reports indicate the presence of small tissue cysts associated with Sarcocystis neurona infections. Several failed attempts to develop tissue cysts in potential intermediate host using in vitro derived parasites originally isolated from horses with equine protozoal myeloencephalitis suggest that the experimental methods to achieve bradyzoites with those isolates was not possible. Those prior studies reported the lack of detectable sarcocysts based on histology and in vivo feeding trials. Read More

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

Samples of muscle tissue from the diaphragm, oesophagus and/or heart of eight adult red deer (Cervus elaphus hispanicus) from the Quintos de Mora Park in Toledo, Central Spain, were screened for sarcocysts by means of the compression method. From positive samples, individual sarcocysts were excised and examined in wet mounts under a light microscope (LM) in order to study their basic morphology before being preserved for molecular studies. In all red deer examined, only microscopic sarcocysts were found. Read More
