A comparison of the sizes of various microorganisms, cells, and viruses

Microorganisms are so small compared to humans that you might be tempted to think that they’re all about the same size. As this video shows, that is not at all the case. The rinovirus and polio virus are 0.03 micrometers (μm) wide, a red blood cell is 8 μm, a neuron 100 μm, and a frog’s egg 1 mm. That’s… Read more »

Probiotics detoxify harmful chemicals from the body

The study of gut health and the microbiome is on the cutting edge of wellness, and people are returning to diets that include fermented, probiotic foods. Kombucha is massively popular today, as is kefir, sauerkraut, yogurt and other natural homemade foods, and our understanding of the benefits of probiotics continues to grow. We are learning how mood may be heavily influenced… Read more »

The Horror of a World Without Microbes

      Geen reacties op The Horror of a World Without Microbes

It’s not the paradise that germophobes might imagine. A few years ago, while doing research for my book on the beneficial microbes that share our bodies, I went on an inadvisably frenetic weeklong reporting trip that spanned five cities and three time zones. On the final night, I wearily picked up the phone in my hotel room to order some… Read more »

Fiber-fermenting bacteria improve health of type 2 diabetes patients

Dietary fibers promote gut bacteria that benefit blood glucose control The fight against type 2 diabetes may soon improve thanks to a pioneering high-fiber diet study led by a Rutgers University-New Brunswick professor. Promotion of a select group of gut bacteria by a diet high in diverse fibers led to better blood glucose control, greater weight loss and better lipid… Read more »

Yale study reveals gut bacteria can spread to other organs to trigger autoimmune disease

A new study from Yale University has discovered that a certain type of gut bacteria can migrate from the gut to other parts of the body, triggering autoimmune diseases. The research revealed that certain autoimmune conditions, such as autoimmune liver disease and systemic lupus, could potentially be treated with an antibiotic or vaccine that attacks the specific bacteria. A huge… Read more »

Formation of bacterial spores

      Geen reacties op Formation of bacterial spores

Spore “memory” links different stages of the bacterial life cycle Bacterial spores store information about the individual growth history of their progenitor cells, thus retaining a “memory” that links the different stages of the bacterial life cycle. This phenomenon was demonstrated in a recent study by an interdisciplinary research team led by Dr Ilka Bischofs at the BioQuant Centre of… Read more »

In soil-dwelling bacteria, scientists find a new weapon to fight drug-resistant superbugs

It’s a new class of antibiotic that promises to live up to its rough Latin translation: killer of bad guys. In a report published this week in the journal Nature Microbiology, researchers describe a never-before-seen antibiotic agent that vanquished several strains of multidrug-resistant bacteria. In rats, the agent — which the researchers dubbed malacidin — attacked and broke down the cell walls… Read more »
