Micronema, normally free-living in soil and humus, rarely invades and reproduces in the central nervous system, kidneys, lungs, maxillae and nasal cavity of equines. Two Micronema infections causing fatal meningoencephalomyelitis in man have been reported from Canada and Texas. Here we report a third infection in a 54-year-old black man, resident of Washington, D.C., who probably acquired the infection from decubitus ulcers. The worms in this patient were in the liver, heart and brain. The Micronema species was not identified.
