Parasitic Infection (Microsporidiosis Encephalitozoonosis) in Dogs
Encephalitozoonosis (microsporidiosis) in Dogs
Encephalitozoon cuniculi (E. cuniculi) is a protozoal parasitic infection in dogs which spreads and creates lesions on the lungs, heart, kidneys, and brain, significantly effecting their ability to function normally. This disease is also commonly called microsporidiosis, as the E. cuniculi is a parasite belonging to the species of microsporidia.
It is a relatively rare infection in dogs, and is better known for its effects on rabbit populations. Microsporidial infection appears to be acquired by the oronasal (mouth and nose) route, when an animal licks/sniffs the
Treatment is experimental, with supportive therapy being the most dominant treatment. In most cases infected dogs will recover fully without medical treatment, but it is often fatal when acquired by puppies (most often while developing in the womb, or while nursing). Puppies may be stillborn, or will die while young from failure to thrive.
In addition, this parasitic infection is zoonotic and therefore contagious to humans, particularly those who are immunocompromised. Sanitizing the environment is essential; a 70 percent ethanol solution should be used to clean up any infected urine and throughout the dog's living area.
Symptoms and Types
Neonatal infection (appears around three weeks of age)
Your veterinarian will conduct a thorough physical exam of your dog after taking a complete history from you. You will then need to provide as much background information as possible about your dog's health and all of the symptoms leading up to the visit. If your dog has recently given birth, or you have puppies being treated, the puppies may be very small with a poor, dull-looking hair coats.
Because some dogs exhibit uncharacteristic aggression, your veterinarian may want to test for rabies and distemper as well. If your dog is an adult, it may have limited vision, complete blindness, or it may be having occasional seizures. Your veterinarian will order a chemical blood profile, a complete blood count and a urinalysis to see which organs the parasite has infected. The infectious spores can be seen in urine that has been stained to make the spores visible under a microscope.
