👉 Macrocephalin, also known as "microfilaria," is a type of protozoan parasite that infects the nervous system in mammals. It is characterized by its small size and the ability to grow within the body through the invasion of microfilariae (microfilarial parasites). Macrocephalin parasitizes the brain, spinal cord, and central nervous system, causing a variety of neurological disorders including seizures, cognitive impairment, and even death in some cases.
