🐛 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.

Cultures have an incredible impact on our society, and not just anthropologically. Cultures in a microbial context have an equally significant impact on the industries that allow us to live the lives that we want.

During her work at Rutgers University microbiologist Elizabeth Bugie (1920-2001) was involved in the discovery of streptomycin, the first antibiotic effective against tuberculosis. While her boss received the Nobel Prize for this discovery, she wasn’t mentioned. Honouring her work on the discovery and evaluation of antibiotics, DSMZ researchers named the strain Streptomyces bugieae (DSM 41528) after her.

Fanny Hesse (1850-1934) worked unpaid for her husband Walter Hesse in Robert Koch's laboratory. Koch was desperate to find a suitable medium for growing bacterial cultures. Fanny Hesse came up with the idea of using agar, which proved to be an ideal gelling agent. To honour her for introducing agar and revolutionising microbiology, DSMZ researchers named the strain Streptomyces hesseae (DSM 40473) after her.

I got just followed by 'Microbiology Journal Club' (@MicrobioJC ) 😊

They made a ton of cool videos about microbiology and criticizing scientific papers during the pandemic (https://www.youtube.com/c/Defectivebrayne/) .

And it gets better: behind is a project of
'Biotech Without Borders, a self-sustaining community of scientists committed to increasing the accessibility of scientific resources and knowledge, especially among socially and economically marginalized groups. We provide education, lab facilities, and a forum for critical discussions to support responsible innovation in biotechnology.'
