The
species Eimeria elephantuli is the
first coccidian parasite that has been found in the rufous elephant shrew, Elephantulus rufenscens (Modrý, Jirků, Hůrková, 2005). Coccidian parasites are
single-celled organisms and need an animal cell to live and reproduce in. Other
species in the subclass of coccidia can be found in pets such as dogs, and
infect animals through consumption of contaminated soil or feces. Coccidiosis
is dangerous for puppies because it may cause bloody diarrhea and death if left
untreated (CAPC 2012).
So far, only two species of Eimeria have been discovered and
reported from insectivores in Africa, but the two differ greatly in general
appearance and can be told apart easily by these differences. E. elephantuli is easy to distinguinsh
from the other species of Eimeria
because of the characteristics of the oocysts, including size, morphology, and
the shape of intracellular bodies (Modrý, Jirků,
Hůrková, 2005). Further research is needed to know where E. eufenscens picks up the infection though it is likely it eats
infected prey.

This is a very informatative article! I've heard that there are issues dealing with acquired resistance of anticoccidial drugs in poultry flocks and fowl. These drugs are used to control the coccidian parasite however, birds have developed immunity to certain strains of the drug. However, it was found that a certain type of chickens, broiler chickens,can develop a natural immunity to the parasite when exposed to low levels of continuous Eimeria species.

I find this to be very interesting - its amazing the diversity of mammals coccidia can inhabit. I wasn't familiar with Elephantulus rufenscens so I looked it up - it makes me ten times more interested. They're adorable animals.
ReplyDeleteI wish you explained why it was called the elephant shrew, or what it looks like, now I have to go all the way to google images... :( Nice review though
