According to the Argonne National Laboratory, there are about one trillion quintillion microbial cells on this planet, which is more than there are stars in the known universe.

Some of the Olympic venue sites have been cleaned up using bioremediation as part of one of the world’s largest brownfield regeneration projects. Brownfield sites are previous industrial sites and include the Aquatic Centre, where the ground was contaminated with lubricating oil. The process used indigenous microbes to aerobically biodegrade the oil, supported with REGENESIS’ Advanced Oxygen Release Compound, which released oxygen over 12 months.

Children brought up with animals, and youngest children in families, are often the least likely to get asthma,  and this may be down to the microbiome (all the bacteria) in the home’s house dust. Mice fed house dust from homes with dogs were more likely to be immune to respiratory syncytial virus (RSV) than mice fed with dust from non-dog homes. RSV is a common childhood infection, and children exposed to it are more likely to get asthma.The microbes in their gut were also different.

The hygiene hypothesis suggests that we get more allergies now because our immune systems don’t have enough to do. Hookworms might be able to cure allergies – but a dog is much more fun to take for a walk!

Breastfeeding helps to colonise babies’ guts with healthy bacteria, and this changes how they express the genes for immunity, improving their immune systems. Read the paper in Genome Biology.
