Abstract The genus Pelomyxa includes 15 species of anaerobic Archamoebae with remarkable diverse nucleoplasm morphology. Nuclear structures, like chromatin and nucleoli, several members the was previously identified only based on their ultrastructural similarity to typical structures somatic cells higher eukaryotes. Here, we explored an easy‐to‐use, one‐step intravital staining method DAPI pyronin distinguish between DNA RNA in nuclei unfixed belevskii P. stagnalis significantly varying by...
The capacity to learn new efficient systemic behavior is a fundamental issue of contemporary biology. We have recently observed, in preliminary analysis, the emergence conditioned some individual amoebae cells. In these experiments, cells were able acquire migratory patterns and remember them for long periods their cellular cycle, forgetting later on. Here, following similar conceptual framework Pavlov's we exhaustively studied migration trajectories more than 2000 belonging three different...
Amoeba proteus is possibly the best known of all unicellular eukaryotes. At same time, several quintessential issues its biology, including some aspects cell cycle, remain unsolved. Here, we show that this obligate agamic amoebae and related species have a special type cyclic polyploidy. Their nucleus has an euploid status only for small fraction during metaphase telophase. The rest time it aneuploid status, which consequence polyploidization. Extrusion "excess" chromatin from in late...
This paper presents the results of a study and describes new species pelobionts, Pelomyxa pilosa sp. nov. (Archamoebae: Pelobiontida). was found in bottom sediments pond near St Petersburg (Russia) examined using light, immunofluorescence, transmission electron microscopy. It is placed genus Greeff, 1874 based on combination morphological features, including mode locomotion, presence numerous flagella, organisation cytoplasm, obligate prokaryotic endocytobionts. The can be easily...
Abstract Background Some pathogenic bacteria have been developing as a part of terrestrial and aquatic microbial ecosystems. Bacteria are consumed by bacteriovorous protists which readily larger organisms. Being natural predators, protozoa also an instrument for selection virulence traits in bacteria. Moreover, serve “Trojan horse” that deliver pathogens to the human body. Here, we suggested carnivorous amoebas feeding on smaller might “Troy” themselves when delivered them with their preys....
