“…Based on the descriptive criteria defined by the International Committee of Zoological Nomenclature (ICZN), the phylum Microsporidia currently comprises over 200 genera [26]. Phylogenetic analysis (based upon small subunit rRNA partial gene sequence) of 70 of these genera reveals five apparent clades broadly classified into three major groups according to predominant host and environment type, termed the Aquasporidia (clades 1 and 3), the Terresporidia (clades 2 and 4), and the Marinosporidia (clade 5) [27].…”

Intensification of food production has the potential to drive increased disease prevalence in food plants and animals. Microsporidia are diversely distributed, opportunistic, and density-dependent parasites infecting hosts from almost all known animal taxa. They are frequent in highly managed aquatic and terrestrial hosts, many of which are vulnerable to epizootics, and all of which are crucial for the stability of the animal–human food chain. Mass rearing and changes in global climate may exacerbate disease and more efficient transmission of parasites in stressed or immune-deficient hosts. Further, human microsporidiosis appears to be adventitious and primarily associated with an increasing community of immune-deficient individuals. Taken together, strong evidence exists for an increasing prevalence of microsporidiosis in animals and humans, and for sharing of pathogens across hosts and biomes.

“…These species were transferred later to genera Pleistophora and Microsporidium , respectively (Sprague ; Becnel et al. ). Infection in an Asian Water Snake was probably associated with another intramuscular Pleistophora ‐like microsporidium, because it was reported to produce larger numbers of spores (320–360) within pansporoblasts (Narasimhamutri et al.…”

The microsporidium parasitizing Inland Bearded Dragons Pogona vitticeps, and developing primarily in macrophages within foci of granulomatous inflammation of different organs, is described as a new species Encephalitozoon pogonae. Establishing the new species was based on sequencing the ITS-SSUrDNA region of the ribosomal gene and consequent SSUrDNA-inferred phylogenetic analyses, as well as on comparison of pathogenesis, host specificity, and ultrastructure among Encephalitozoon species and isolates. The new species is closely related to E. lacertae and E. cuniculi. Analysis of the literature suggests that this microsporidium has been reported previously as an unidentified microsporidian species or isolate of E. cuniculi and may represent a common infection in bearded dragons. All stages of E. pogonae develop in parasitophorous vacuoles. Uninucleate spores on methanol-fixed smears measured 2.1 × 1.1 μm, range 1.7-2.6 × 0.9-1.7 μm; on ultrathin sections spores measured 0.8-1.1 × 1.8-2.2 μm. Ultrastructural study revealed 3-6 polar filament coils, a mushroom-shaped polar disk, and a polar sac embracing half of the volume occupied by the lamellar polaroplast. In activated spores, polar filament everted eccentrically. The overall morphology and intracellular development of E. pogonae were similar to other Encepahalitozoon spp. We also review the existing data on microsporidia infecting reptiles.

The Microsporidium, Anncaliia algerae, an obligate intracellular parasite, has been identified as an opportunistic human pathogen but treatment has not been evaluated for infections with this organism. Albendazole, an anti-tubulin polymerization drug used against parasitic worm infections, has been the medication of choice used to treat some microsporidial infections affecting humans, with varying results ranging from clearing infection (Encephalitozoon) to resistance (Enterocytozoon). This study illustrates the effect of albendazole treatment on A. algerae infection in Rabbit Kidney (RK13) cells and Human Fetal Lung (HFL-1) fibroblasts. Albendazole appears to have an attenuating effect on A. algerae infection and albendazole’s IC50 in RK13 cells is 0.1μg/ml. Long-term treatment inhibits up to 98% of spore production, but interrupting treatment re-establishes the infection without new exposure to the parasite as supported by microscopic observations. The parasite’s Beta-Tubulin gene was purified, cloned, and sequenced. Five of the six specific amino acids, associated with benzimidazole sensitivity, are conserved in A. algerae. These findings suggest that A. algerae is sensitive to albendazole; however, the organism is not completely cleared from cultures.
