N2 - The genus Deuteramoeba is one of the six amoebae genera belonging to the best-known amoeba family – Amoebidae (Amoebozoa, Tubulinea), containing such a popular species as Amoeba proteus. However, members of other genera of the family Amoebidae are much less known, and most of the studies of their morphology and ultrastructure date back to the 1970s and 1980s. Since these “classical” species are believed to be “well studied”, their morphology and fine structure rarely become a subject of re-investigation. The absence of modern morphological data may be critical when molecular data of the type strain are not available, and the only way to identify a species is by morphological comparison. For this paper, we performed an ultrastructural study of the strain CCAP 1586/1 – the type strain of the species Deuteramoeba mycophaga. Our study revealed new details of the nuclear structure, including a peripheral layer of filaments and a heterogeneous nucleolus, and provided new data on the cytoplasmic inclusions of this species. We performed a whole-genome amplification of the DNA from a single amoeba cell followed by NGS sequencing and searched for genetic evidence for the presence of a putative nuclear parasite detected in 2017, but found no evidence for the presence of Opisthosporidia.
