Coccidia species screen
X0024 - Ultrasensitive qualitative detection of many coccidia species by
real time PCR. This assay detects but does not differentiate many
species including Cryptosporidium, Eimeria,
Hammondia, Hepatozoon, Isospora, Neospora, Sarcocystis, and
Coccidiosis refers to diseases
caused by coccidian infections. Coccidia is a diverse subclass of parasitic protozoa
that includes many genera, such as Cryptosporidium, Eimeria, Hammondia,
Hepatozoon, Isospora, Neospora, Sarcocystis, and Toxoplasma.
These parasites usually infect the intestinal tracts of animals,
causing diarrhea. In some cases, coccidia can migrate to the central
nervous system and cause neurologic symptoms or death.
Coccidia usually spread from one
animal to another through contact with infected feces or ingestion of
infected tissues. Most infections result in asymptomatic carriers of
the parasites, especially in adults. However, these carriers can
continuously shed the parasites in their feces, thereby infecting
other animals. Young or immunocompromised animals may suffer severe
symptoms, including death.
While coccidia can infect a wide variety of animals, including humans,
birds and livestock, they are usually species-specific. One well-known
exception is toxoplasmosis caused by Toxoplasma gondii:
humans may become infected with this parasite while handling infected
pets, especially cats, or their feces.
In the past, diagnosis of coccidian infections
relied on fecal float, a technique which is relatively insensitive and
not very precise.
However, molecular detection by polymerase chain reaction is rapid,
highly sensitive and highly specific (Lalonde and Gajadhar, 2011).
