Five cases of microsporidioses among leukemic patients, 4 in myeloid-leukemic patients and 1 in a chronic lymphocytic leukemia, have been described until now. We report a case of microsporidiosis and the genomic identification of Encephalitozoon hellem in a patient with CD4(+) T-cell prolymphocytic leukemia.

Although the etiological relevance of the detection of microsporidia in human stool samples remains uncertain, the immunological status of patients has been posited as an important determinant of potential clinical impact of these parasites. To further assess the interplay between the epidemiology of microsporidia and immunological markers, we conducted a study utilizing real-time PCR targeting , , , and , combined in a single fluorescence channel. The study involved a cohort of 595 clinically and immunologically well-characterized Ghanaian HIV patients, alongside 82 HIV-negative control individuals from Ghana.

To determine the occurrence of microsporidiosis in domestic pigeons in Iran, privately-owned pigeons presenting weight loss and diarrhea were tested through molecular and histopathological methods. Multiplex-PCR findings showed 57%, 30%, and 14% positivity for , , and mixed infection in the fecal samples, respectively. A novel genotype, named IrnEb1, falling into zoonotic group 1 of , and a novel genotype of , named Irn2E, clustering as a sister taxon to genotype 2B were identified in pigeons for the first time using Sanger sequencing and phylogenetic analyses.

Background: Microsporidia are opportunistic intracellular parasites that cause a variety of illnesses in humans. There is little information available regarding the frequency of this parasite in human cases of diarrhea and cancer.
Aim: This study's primary objectives are to identify microsporidia in soil and water samples, determine the relationships between microsporidia by using sequencing analysis in the targeted area, and look into the genetic diversity of microsporidia originating from domestic, farm, and wild animals.

Purpose: To assess the clinical characteristics, progression patterns, and treatment outcomes of microbiologically confirmed microsporidial keratoconjunctivitis (MKC).
Methods: This prospective cross-sectional study included patients with superficial punctate epithelial keratitis clinically suspected of MKC. Comprehensive slit-lamp examinations were conducted, and corneal scraping was performed for Gram-chromotrope staining and polymerase chain reaction (PCR) analysis.
