Abstract

Limited data exist on human Macracanthorhynchus infections. We report an asymptomatic 17-month-old who passed eggs and an adult Macracanthorhynchus ingens worm, indicating parasite maturation and reproduction. Macracanthorhynchus ingens may have a greater capacity to mature in humans versus Macracanthorhynchus hirudinaceus.

Keywords: Macracanthorhynchus spp; helminth; parasite.
