Sarcocystis neurona PCR test for dogs and cats

X0004 - Ultrasensitive qualitative detection of
Sarcocystis neurona by
real time polymerase chain reaction
is a parasitic protozoan which is the most important cause of a
serious neurological disease of horses called equine protozoal
myeloencephalitis (EPM). S.
neurona also causes EPM-like disease in other mammals
including dogs, cats, mink, raccoons, skunks, sea otters and Pacific harbor
seals ( Dubey et al., 2001). While the life cycle of
S. neurona is not fully
understood, it is known that opossums (Didelphis
albiventris) are its definitive hosts.
from Michigan and Florida reported
S. neurona antibodies in
5% of domestic cats based on Western blot analysis (Gillis et al.,
2003; Rossano et al., 2002). This suggests a more widespread problem
in domestic cats than was previously thought.
detection of this parasite is not very sensitive and not very
specific. Many infected cats are carriers and shed the sporocysts in
their feces. Molecular detection by PCR can offer a rapid, sensitive
and specific method for determining the infection status of an animal.
