Evolutionary Dynamics of Giant Viruses and their Virophages [PDF]
, 2013 Giant viruses contain large genomes, encode many proteins atypical for viruses, replicate in large viral factories, and tend to infect protists. The giant virus replication factories can in turn be infected by so called virophages, which are smaller ...

Environmental stress promotes the persistence of facultative bacterial symbionts in amoebae
Ecology and Evolution, 2023 Amoebae are one major group of protists that are widely found in natural and engineered environments. They are a significant threat to human health not only because many of them are pathogenic but also due to their unique role as an environmental shelter

Bordetella bronchiseptica exploits the complex life cycle of Dictyostelium discoideum as an amplifying transmission vector. [PDF]
PLoS Biology, 2017 Multiple lines of evidence suggest that Bordetella species have a significant life stage outside of the mammalian respiratory tract that has yet to be defined.

Intersecting Solitons, Amoeba and Tropical Geometry
, 2008 We study generic intersection (or web) of vortices with instantons inside, which is a 1/4 BPS state in the Higgs phase of five-dimensional N=1 supersymmetric U(Nc) gauge theory on R_t \times (C^\ast)^2 \simeq R^{2,1} \times T^2 with Nf=Nc Higgs scalars ...

Neurofibromin controls macropinocytosis and phagocytosis in Dictyostelium
eLife, 2015 Cells use phagocytosis and macropinocytosis to internalise bulk material, which in phagotrophic organisms supplies the nutrients necessary for growth. Wildtype Dictyostelium amoebae feed on bacteria, but for decades laboratory work has relied on axenic ...

Dimer models from mirror symmetry and quivering amoebae [PDF]
, 2008 Dimer models are 2-dimensional combinatorial systems that have been shown to encode the gauge groups, matter content and tree-level superpotential of the world-volume quiver gauge theories obtained by placing D3-branes at the tip of a singular toric ...

Microbiology Spectrum, 2023 The diatom Phaeodactylum tricornutum is regarded as a prospective “cell factory” for the high-value products fucoxanthin and eicosapentaenoic acid (EPA). However, contamination with grazing protozoa is a significant barrier to its commercial cultivation.
