Microbial Interaction

We may think of ourselves as a highly evolved species of conscious individuals, but we are all far less human than most of us appreciate. Scientists have long recognized that the bacterial cells inhabiting our skin and gut outnumber human cells by ten-to-one.

Indeed, Princeton University scientists compared the approximately 30,000 human genes found in the average human to the more than 3 million bacterial genes inhabiting us, concluding that we are at most [Read more…]

Normal Flora of the Skin

The mixture of organisms regularly found at any human anatomical site is referred to as the normal flora. Populations of microbes – such as bacteria and yeasts – inhabit the skin and mucus surfaces and are the body=s first lines of defense against illness and injury.

Their health depends upon the delicate balance between our own cells and the millions of bacteria and other one-celled microbes. Their role forms part of normal, healthy human physiology, however if microbe [Read more…]

A Day Without Microbes

A world without bacteria may seem ideal at first. But the more we think about it, the more we realize that we cannot live without microbes.

There would be no food poisoning, no diarrhea, no coughs and colds, no sore throats, no tuberculosis, no cholera, no small pox, no polio, no sexually transmitted diseases. There would be no decay. Foods would [Read more…]

The importance of beneficial bacteria for a healthy baby

Doctors have long known that infants who are breast-fed contract fewer infections than those who are given formula. Humans are born extremely immature, with the major organs and immune system not fully developed.

For its survival the infant depends on an extraordinary well-adapted evolutionary strategy shared by all mammals, breast-feeding. But what [Read more…]
