🐛 Mixotricha paradoxa — the protist that swims using 250,000 living bacteria as outboard motors

When first described in 1933, Mixotricha paradoxa appeared to swim using thousands of hair-like cilia. Electron microscopy in the 1960s revealed the truth: those "cilia" were actually ~250,000 individual spirochete bacteria anchored to its outer membrane, beating in synchrony to propel the host cell.

This single-celled organism lives exclusively in the hindgut of Australia's primitive giant termite (Mastotermes darwiniensis). It has no mitochondria and no independent mobility — its four flagella act only as rudders, while the bacterial swarm does all the work. Evolutionary biologist Lynn Margulis called it "the beast with five genomes" because it is a composite of host, two species of propulsion spirochetes, surface rod bacteria, and internal wood-digesting endosymbionts.

Mixotricha dies within minutes of oxygen exposure and has never been cultured in a lab. It is considered a living snapshot of symbiogenesis — the theory that complex eukaryotic cells arose when ancient prokaryotes merged into single functioning entities, frozen mid-transition.

Researchers have discovered that metabolites produced by a specific gut bacterium can significantly enhance the body's immune response to cancer. The bacterium Bacteroides uniformis converts the amino acid tryptophan into indoles, which subsequently suppress tumor growth and boost anti-tumor immunity.

Our new research project MicroSafe focuses on the impact of climate change on microbial growth in wet cooling towers. The research focuses on the spread of pathogenic microorganisms, such as Legionella, from wet cooling towers. The Netherlands has at least 4,000 of these cooling towers, which are used for cooling buildings and industrial installations. Due to climate change and higher temperatures, the risk of pathogen spread may increase. https://www.ru.nl/en/research/research-news/nwo-funding-for-research-project-on-the-effects-of-climate-change-on-microbial-growth-in-cooling-towers
