Microsporidia are a large group of microbial eukaryotes composed exclusively of obligate intracellular parasites of other eukaryotes. Almost 150 years of microsporidian research has led to a basic understanding of many aspects of microsporidian biology, especially their unique and highly specialized mode of infection, where the parasite enters its host through a projectile tube that is expelled at high velocity. Molecular biology and genomic studies on microsporidia have also drawn attention to…

The intriguing nature of microsporidian

The current understanding of the genome content and structure of microsporidia is reviewed, discussing their evolutionary origin and cataloguing the mechanisms that have often been involved in their extreme reduction.

The most significant recent advances in microsporidian genomics are detailed and discussed and how these have affected the understanding of many biological aspects of these peculiar eukaryotic intracellular pathogens are discussed.

Evolution of the microsporidian genome and gene expression

A combined eight-gene dataset was employed using multiple phylogenetic methods in order to identify the closest fungal relative of microsporidia, and it was found that microspora proteins interact with each other using different functional residues and in the absence of proteins that are used in yeast.

The Microsporidia are a large diverse group of obligate, intracellular parasites that have small genomes in the size range of prokaryotic cells and are now thought to be highly evolved fungi.

Latest Progress in Microsporidian Genome Research

This study aims to shortly review the most recent progress in the field of microsporidian genomics, highlighting the importance of the most recently released genome data for the understanding of the biology and evolution of this important group of parasites.

Genome and Evolutionary Analysis of Nosema ceranae: A Microsporidian Parasite of Honey Bees

A robust 8.8 Mbp genome assembly of 2,280 protein coding genes is presented, including a high number of genes involved in transporting nutrients and energy, as well as drug resistance when compared with sister species Nosema apis.



Microsporidian Biochemistry and Physiology

This chapter focuses on keratin filaments found in two domains: within the spore stage, the microsporidian sporophorous vesicle, and keratin in the host cell cytoplasm domain but situated at its interface with the parasite.

Ribosomal RNA sequence suggests microsporidia are extremely ancient eukaryotes

Comparison sequence analysis shows that the small subunit rRNA of the microsporidium Vairimorpha necatrix is more unlike those of other eukaryotes than any known eukARYote 18S rRNA sequence, and concludes that the lineage leading to microspora branched very early from that leading to other eUKaryotes.

Genome sequence and gene compaction of the eukaryote parasite Encephalitozoon cuniculi

The DNA sequences of the 11 chromosomes of the ∼2.9-megabase (Mb) genome of Encephalitozoon cuniculi are reported and it is hypothesize that microsporidia have retained a mitochondrion-derived organelle.

Evidence from beta-tubulin phylogeny that microsporidia evolved from within the fungi.

Overall, beta-tubulin phylogeny suggests that microsporidia evolved from a fungus sometime after the divergence of chytrids, and it is found thatChytrid alpha- and beta- Tubulins are much less divergent than are tubulins from other fungi or microsporaidia.

Human microsporidial infections

Progress is being made with respect to in vitro propagation of microsporidia, which is crucial for developing antimicrosporidial drugs, and molecular techniques are being developed for diagnostic purposes, taxonomic classification, and analysis of phylogenetic relationships.

A proposal for typical eukaryotic meiosis in microsporidians

It is proposed that confusion resulted because two separate cytological developmental sequences for diplokaryotic meronts in mosquito fat body cells were previously interpreted as a single sequence and a better fit was obtained between cytological stages and microphotometric measurements of nuclear DNA content.

Characterization and function of the microsporidian polar tube: a review.

A method for the purification of polar tube proteins (PTPs) using differential extraction followed by reverse phase high performance liquid chromatography (HPLC) was developed, used to purify for subsequent characterization PTPs from Glugea americanus, Encephalitozoon cuniculi, E. hellem and E. intestinalis.
