Five out of one hundred adults of Niphargogammarus intermedius caught at the Azov sea shore were found to be infected with microsporidia. The infection was found in the subcuticular fat body and myocytes. Parasites developed in direct contact with host cells, displayed a disporoblastic sporogony and diplokaryotic arrangement of nuclei at all stages. Spores were oval, 4.6-5.8 × 2.6-3.0 μm. Exospore appendages, vesicular-tubular secretions, and the anisofilar polar filament indicated a similarity to Anncaliia species. Sporont surfaces displayed ridges of amorphous material. Meronts and sporonts formed protoplastic extensions, similar to A. vesicularum and A. meligheti. Mature spores possessed a bipartite polaroplast. The polar tube was arranged in one row of 13-18 coils including 0-3 distal coils of lesser diameter. Partial sequencing of SSU, ITS, and LSU regions of rRNA gene (GenBank accessions: KY288064-KY288065) confirmed this new species to be congeneric with A. algerae (#AF069063) and A. meligheti (#AY894423). The SSU gene of this novel microsporidium shared 99.4% sequence similarity to A. algerae and 98.9% to A. meligheti. Genes for HSP70 and RPB1 amplified with primers designed for A. algerae orthologs displayed 99.7% and 97.4% similarity, respectively, between A. algerae and the novel microsporidium. A new species, Anncaliia azovica, is described based on morphological and molecular characterization.

“…Such variations prove once again that the nuclear phase, and type of sporogony (polysporoblastic vs. disporoblastic) can vary in closely related species as it has been previously demonstrated for Liebermannia spp. (Sokolova et al, 2009).…”

“…A possible explanation is the divergence of these forms from a common ancestor with two dissimilar developmental sequences proceeding within determinative and intermediate hosts, respectively. In another case, three species of the genus Liebermannia, all from orthopteran insects, are similar in ultrastructure but different in nuclear phase, so that the presence of diplokaryotic spores is removed from the revised genus diagnosis (Sokolova et al 2009). Another example is the taxonomy of Nosema/Vairimorpha clade in which assignment to one of these two genera, formally based upon developmental sequence, is not congruent with phylogenetic relationships, substantiating the need for revision of these taxa (Baker et al 1995;Kyei-Poku et al 2008).…”

Life cycle, ultrastructure, and molecular phylogeny of Crispospora chironomi g.n. sp.n. (Microsporidia: Terresporidia), a parasite of Chironomus plumosus L. (Diptera: Chironomidae)

The life cycle, ultrastructure, and molecular phylogeny of a new microsporidium Crispospora chironomi g.n. sp.n., a parasite of the midge Chironomus plumosus, are described. The parasite infects the gut epithelium of the host larvae and possesses sporogonies of two types, polysporoblastic and disporoblastic, respectively, proceeding within the same host cell. In the sporogonial sequence of the first type, dozens of spherical monokaryotic spores within a thick-walled capsule are formed. The spores are 1.5-2.0 μm in diameter; the exospore possesses two to three bundles of tubular protrusions. In the sporogonial sequence of the second type, diplokaryotic oval spores, 2.5 × 1.5 μm in size, are formed within a compartment, partially surrounded with multilayered membranes. Spores of both types are similar in respect to inner structure, possessing a well-developed extrusion apparatus with (a) the anterior vesicular part of the polaroplast covering the lamellar posterior one and (b) isofilar polar filament with several coils in one row. Small subunit ribosomal DNA phylogeny showed position of the new microsporidium in a cluster uniting microsporidia of terrestrial origin infecting diverse hosts, nested within Clade IV, corresponding to Class Terresporidia sensu Vossbrinck and Debrunner-Vossbrinck (Folia Parasitol 52:131-142, 2005).
