A new study has shown that restoring environments to include a wider range of species can promote 'good' bacteria over 'bad' -- with potential benefits for human health. University of Adelaide researchers report, in the journal Environment International , that degraded, low biodiversity land and soils tend to harbour more 'opportunistic' bacteria, while healthy, biodiverse ecosystems favour more stable and specialist bacteria. They found that the bacterial communities more commonly found in degraded landscapes had "potential pathogenic character," with many in the same genera as prominent disease-causing bacteria Bacillus, Clostridium, Enterobacter, Legionella and Pseudomonas. Restoring a more biodiverse ecosystem, however, changed the bacterial composition towards more potentially immune-boosting microbial diversity.
What are bacteria and what do they do?
Many probiotics are similar to bacteria that are naturally living in your body. You may already be consuming some of these good bacteria if you eat fermented products, such as:. The concept of consuming more good microbes to aid health has been discussed since the early s. However, the science is not yet conclusive on all the benefits of probiotics for healthy people or for treatment of particular diseases. Today, many kinds of probiotics are commercially available in foods and supplements. As the National Center for Complementary and Integrative Health reports, some experts have warned that the rapid growth in probiotics marketing and use may have outpaced scientific research on the benefits. Your bowels host an estimated trillion microorganisms from more than different species, according to Harvard Medical School.
Scientists have observed bacteria using microscopes to identify them. But it is the living processes that bacteria use and the wastes they give off that can be used either for human benefit or that cause disease. Scientists believe it was the chemical processes of early cyanobacteria, harnessing the energy from the sun, that released the oxygen that makes up our atmosphere. It took approximately 2 billion years for the bacteria to build up enough oxygen in the atmosphere to allow for the evolution of multi-cellular organisms. Bacteria have long been used by humans to create food products such as cheese, yoghurt, pickles, soy sauce and vinegar. We are also able to use bacteria to break down our sewage and to clean up oil spills.

The oral microbiome – an update for oral healthcare professionals
Bacteria are single celled microbes. The cell structure is simpler than that of other organisms as there is no nucleus or membrane bound organelles. Instead their control centre containing the genetic information is contained in a single loop of DNA. Some bacteria have an extra circle of genetic material called a plasmid.
The human body is inhabited by millions of tiny living organisms, which, all together, are called the human microbiota. Bacteria are microbes found on the skin, in the nose, mouth, and especially in the gut. We acquire these bacteria during birth and the first years of life, and they live with us throughout our lives. The human microbiota is involved in healthy growth, in protecting the body from invaders, in helping digestion, and in regulating moods.
The scientific evidence supporting the gut microbiome in relation to health maintenance and links with various disease states afflicting humans, from metabolic to mental health, has grown dramatically in the last few years. Strategies addressing the positive modulation of microbiome functionality associated with these disorders offer huge potential to the food and pharmaceutical industries to innovate and provide therapeutic solutions to many of the health issues affecting modern society. Such strategies may involve the use of probiotics and prebiotics as nutritional adjunct therapies.
