The best option for diagnosis is using PCR. Diagnosis with Microsporidia can be done through gram-positive, acid-fast spores in stool and biopsy material with morphologic demonstration of the organism. Initial detection through light microscopic examination of tissue sections, stools, duodenal aspirates, nasal discharges, bronchoalveolar lavage fluids, and conjunctival smears. Definitive diagnosis can also be achieved through fluorescein-tagged antibody immunofluorescence or electron microscopy, and species identification can be done through PCR. Classification Although it is classified as a protozoal disease in ICD-10, their phylogenetic placement has been resolved to be within the Fungi, and some sources classify<unk>  as a mycosis, however, they are highly divergent and rapidly evolving.
