Microsporidia are obligate intracellular parasites that were thought to be an ancient eukaryotic lineage based on molecular phylogenies using ribosomal RNA and translation elongation factors. However, this ancient origin of microsporidia has been contested recently, as several other molecular phylogenies suggest that microsporidia are closely related to fungi. Most of the protein trees that pla...

Introduction: Immunocompromised host has one or more defects in the normal defense mechanisms that protect against infectious agents. Microsporidia are group of protozoa characterized via obligate intracellular and spore formation, detected many hosts. Up till now, 1300 microsporidia species more, related to 150 genera, were, microsporidiosis caused by microsporidia. Objectives: To conduct Mole...

PURPOSE Developing a DNA dot hybridization model for diagnosing parasitic keratitis. METHODS Newly designed oligonucleotide probes for detecting Acanthamoeba and microsporidia were tested with target reference strains of Acanthamoeba (n = 20) and microsporidia (n = 3), and non-target microorganisms, including bacteria (n = 20) and fungi (n = 20). These probes, which had passed the preliminary...

Microsporidia comprise a phylum of obligate intracellular pathogens related to fungi. Microsporidia Nematocida sp1 strain ERTm6 was isolated from wild-caught Caenorhabditis briggsae and causes a lethal intestinal infection in Caenorhabditis nematodes. We report the genome sequence of N. sp1 ERTm6, which will facilitate study of the Nematocida genus and other Microsporidia.

Microsporidia are fungi-related intracellular pathogens that may infect virtually all animals, but are poorly understood. The nematode Caenorhabditis elegans has recently become a model host for studying microsporidia through the identification of its natural microsporidian pathogen Nematocida parisii. However, it was unclear how widespread and diverse microsporidia infections are in C. elegans...

Although attempts to develop methods for the in vitro cultivation of microsporidia began as early as 1937, the interest in the culture of these organisms was confined mostly to microsporidia that infect insects. The successful cultivation in 1969 of Encephalitozoon cuniculi, a microsporidium of mammalian origin, and the subsequent identification of these organisms as agents of human disease hei...

The members of the Microsporidia are single-celled, eukaryotic, obligate intracellular parasites. They infect a wide range of invertebrate and vertebrate hosts. The studies on Microsporidia are of considerable interest because of that they cause desirable and undesirable infections in different animals. That situation requires identification of these organisms correctly. The identification of M...

Microsporidia are now recognized as important pathogens of AIDS patients; the ability of these parasites to cause disease in immunocompetent persons is still being elucidated. Improved diagnostic tests for microsporidial infection are continually being sought for establishing diagnosis in order to avoid laborious electron microscopy studies that require invasively acquired biopsy specimens.
