ABSTRACT
Microsporidia are a group of obligate intracellular eukaryotic parasites, ubiquitous in nature, and considered as emerging pathogens in humans and animals. Over the past three decades, microsporidia have risen from obscure organisms to well-recognized human pathogens. Several genera and species of microsporidia were found in humans, and diagnosis and clinical management of microsporidiosis cases have improved signicantly. Despite progress, the epidemiology of diseases caused by microsporidia is still poorly known.
