However, the means by which protozoans trigger these cells to produce cytokines were mostly unknown. Recent experimental evidence advances our understanding on this important question. This new ...

"Protozoans are under-estimated players in the history of macroscopic animal life," Matz says. "This is the first evidence that organisms other than multicellular animals can produce such traces.

Protozoans and pathogens make for an infectious mix Date: October 1, 2019 Source: University of Technology Sydney Summary: The new observation that strains of V. cholerae can be expelled into the ...

Researchers have succeeded in revealing the arsenal used by protozoans of the genus Leishmania in human cells to make leishmaniasis more severe, especially in cases of the mucocutaneous variety of ...

Single-celled organisms in the environment are protecting pathogenic bacteria and priming them for human infection, an international team of researchers has discovered. Microorganisms such as protozoa ...

The team collected specimens and identified the creatures as giant protozoans, Gromia sphaerica, each one a single large cell with an organic shell, or "test." When cleaned of sediment ...

Biologists have recently identified some very simple organisms which are the closest living relatives of today's multicellular animals. We did this by sequencing some of the genes shared by both ...

That turns out to be a bad way to count viruses, in part because their hosts–such as bacteria and protozoans–often don’t grow in the artificial confines of a laboratory. Without viable hosts ...
