Bacteria that move around live on the edge. All the time. Their success, be it in finding nutrients, fending off predators or multiplying depends on how efficiently they navigate through their confining microscopic habitats. Whether these habitats are in animal or plant tissues, in waste, or in other materials.

Researchers at 香蕉视频 have discovered bacterial organelles involved in gene expression, suggesting that bacteria may not be as simple as once thought. This finding could offer new targets for the development of new antibiotics.

The study, published in , is the first to show that E. coli uses similar strategies to regulate gene transcription as other more complex cell types.

Lorsqu鈥檜ne contamination bact茅rienne se d茅clare 脿 proximit茅 d鈥檜ne ferme, il faut cibler le plus rapidement possible les 茅levages probl茅matiques puisque certaines souches peuvent parfois infecter l鈥檋omme. L鈥檕bjectif est de mettre en place des barri猫res naturelles qui emp锚cheront les ruissellements provenant de ces fermes de se retrouver dans l鈥檈au potable environnante.

Scientists at the University of Montreal and 香蕉视频 have pioneered and tested a new genomic methodology which reveals a complex bacterial ecosystem at work on the International Space Station.

Until now, relatively little was known about the different types of microbes found on the space station. The new approach enables researchers to identify and map different species inside the ISS, which will ultimately help safeguard astronauts鈥� health and be key to future long-term space travel.

You are what you eat. Or so the saying goes. Science now tells us that we are what the bacteria living in our intestinal tract eat and this could have an influence on how well we age. Building on this, 香蕉视频 scientists fed fruit flies with a combination of probiotics and an herbal supplement called Triphala that was able to prolong the flies鈥� longevity by 60 % and protect them against chronic diseases associated with aging.

The list of 鈥渂ad things鈥� could range from gross but harmless spoilage to dangerous pathogens such as Clostridium botulinum. In the case of botulism, it鈥檚 the toxin produced from the bacteria that is harmful, not the bacteria itself, says Brigitte Cadieux, a postdoctoral fellow in 香蕉视频鈥檚 Department of Food Science and Agricultural Chemistry.
