Blood cells are much smaller than dust mites. A typical blood cell has a diameter of about 6-8 micrometers, while a dust mite can range in size from about 100 to 300 micrometers. Dust mites are visible to the naked eye, whereas blood cells can only be seen under a microscope.


What is the external parasite that causes mange?

The external parasite that causes mange is the mite. Mites are arachnids, eight-legged arthropods that are related to ticks. Like all arthropods, mites have a hard exoskeleton, a segmented body and jointed legs.There are several different forms of mange, each caused by a different species of mite. For instance, demodectic mange is caused by mites of the species Demodex. Scabies, which is also known as sarcoptic mange, is caused by the mite Sarcoptes scabiei. Otodectic mange, caused by Otodectes cynotis, is the most commonly seen mite-related disease in veterinary medicine. Otodectes cynotis are more frequently referred to as ear mites.
