Question

Equine protozoal myeloencephalitis is a disease that locates itself in the central nervous system of the horse. The protozoan that causes the disease is found in opossum feces. Symptoms include stumbling, incoordination, and head tilting.

(True / False)

Answer 1

The student's statement about Equine protozoal myeloencephalitis being a disease that affects the central nervous system of horses and is associated with symptoms like stumbling and incoordination is True. This condition is caused by a protozoan found in opossum feces, distinct from mosquito-transmitted encephalitis viruses.

Step-by-step explanation:

The statement about Equine protozoal myeloencephalitis is True. This disease does indeed affect the central nervous system of horses, and it can cause symptoms such as stumbling, incoordination, and head tilting. The protozoan responsible for this disease is typically found in opossum feces. It's important to differentiate this from other mosquito-transmitted diseases like Eastern equine encephalitis (EEE) and Western equine encephalitis (WEE), which are caused by viruses, not protozoa, and have different transmission vectors, namely various species of mosquitoes. While birds are natural reservoirs for EEEV and WEEV, opossums serve as a source for the transmission of the protozoa that causes Equine protozoal myeloencephalitis.
