Microbes in medicine
There are 100 thousand billion microbes on and in our bodies. That’s ten times more than our own body cells. Microbes are involved in processes like our metabolism, and help keep us healthy by fighting off harmful intruders, for example. Slowly but surely, scientists are beginning to realise – and discover – how important microbes are in the existence and prevention of disease. New discoveries and applications hold promising opportunities for the future.
An ounce of prevention
If the microbes that we carry in our digestive system — called our (intestinal) microbiota — are out of balance, we can become ill. There are indications that we can positively influence that balance by eating healthy intestinal microbes. Previously, researchers could only isolate a select few probiotics (mostly Lactobacilli) from our intestinal microbiota or from fermented products like yoghurt. But the number of probiotics is growing. In 2013, scientists discovered a strain of intestinal bacteria that can, amongst other things, regulate the immune system and the storage of fat. Such bacteria could create a new generation of probiotics, with far more useful effects on our health.

In the pharmaceutical industry, bacteria are used to produce antibiotics, vaccines, and medically-useful enzymes. Most antibiotics are made by bacteria that live in soil. Actinomycetes such as Streptomyces produce tetracyclines, erythromycin, streptomycin, rifamycin and ivermectin.
