| prevalence of neospora hughesi and sarcocystis neurona antibodies in horses from various geographical locations. | parasite-specific antibody responses to neospora antigens were detected using the immunofluorescent antibody test (ifat) and immunoblot analysis in select equine populations. for comparison, a naturally infected neospora hughesi horse and an experimentally inoculated neospora caninum horse were used. in addition, all samples were tested for antibodies to sarcocystis neurona by immunoblot analysis. a total of 208 samples was evaluated. the equine populations were derived from five distinct geogra ... | 2001 | 11223207 |
| prevalence of antibodies to neospora caninum, sarcocystis neurona, and toxoplasma gondii in wild horses from central wyoming. | sarcocystis neurona, neospora caninum, n. hughesi, and toxoplasma gondii are 4 related coccidians considered to be associated with encephalomyelitis in horses. the source of infection for n. hughesi is unknown, whereas opossums, dogs, and cats are the definitive hosts for s. neurona, n. caninum, and t. gondii, respectively. seroprevalence of these coccidians in 276 wild horses from central wyoming outside the known range of the opossum (didelphis virginiana) was determined. antibodies to t. gond ... | 2003 | 14533680 |
| prevalence of antibodies to trypanosoma cruzi, toxoplasma gondii, encephalitozoon cuniculi, sarcocystis neurona, besnoitia darlingi, and neospora caninum in north american opossums, didelphis virginiana, from southern louisiana. | we examined the prevalence of antibodies to zoonotic protozoan parasites ( trypanosoma cruzi, toxoplasma gondii, and encephalitozoon cuniculi) and protozoans of veterinary importance ( neospora caninum, sarcocystis neurona, and besnoitia darlingi) in a population of north american opossums ( didelphis virginiana) from louisiana. samples from 30 opossums were collected as part of a survey for t. cruzi in louisiana. frozen sera from these 30 opossums were examined using an indirect immunofluoresce ... | 2010 | 21158620 |
| serological response of cats to experimental besnoitia darlingi and besnoitia neotomofelis infections and prevalence of antibodies to these parasites in cats from virginia and pennsylvania. | abstract besnoitia darlingi and besnoitia neotomofelis are cyst-forming tissue apicomplexan parasites that use domestic cats ( felis domesticus ) as definitive hosts and opossums ( didelphis virginiana ) and southern plains woodrats ( neotoma micropus ) as intermediate hosts, respectively. nothing is known about the prevalence of b. darlingi or b. neotomofelis in cats from the united states. besnoitia darlingi infections have been reported in naturally infected opossums from many states in the u ... | 2011 | 21506782 |
| sarcocystis neurona and neospora caninum in brazilian opossums (didelphis spp.): molecular investigation and in vitro isolation of sarcocystis spp. | sarcocystis neurona and neospora spp. are protozoan parasites that induce neurological diseases in horses and other animal species. opossums (didelphis albiventris and didelphis virginiana) are definitive hosts of s. neurona, which is the major cause of equine protozoal myeloencephalitis (epm). neospora caninum causes abortion in cattle and infects a wide range of animal species, while n. hughesi is known to induce neurologic disease in equids. the aims of this study were to investigate s. neuro ... | 2017 | 28807293 |
