Pandoravirus enters amoebas through phagocytic vacuoles, then fuses with the membrane vacuole of the amoeba. Pandoraviruses infect amoebas, which are single celled eukaryotes. Tupanviruses are able to infect protists and amoebas, but probably pose no threat to humans. You can imagine domains as being like primitive one-celled organisms (like amoebas). An amoebic brain abscess is a brain abscess caused by amoebas. These include hookworms, roundworms, and other amoebas. Both these viruses infect amoebas specifically. These viruses infects amoebas and can survive in low temperatures. The virus can harden defenseless amoebas into stone-like cysts, but usually burst. A brain biopsy will reveal the presence of infection by pathogenic amoebas. Food may become scarce and cause amoebas to starve, die and decompose into food. The abilities are pictured on the gene cards, showing amoebas growing fins, tentacles, spines, etc. The amoebas started dying and when examined were found to contain giant virus specimens. Amoebas have applications in algebraic geometry, especially tropical geometry. In the majority of cases, amoebas remain in the gastrointestinal tract of the hosts.
