Karl KruszelnickiHOST
mainly a weird chemical called hydroxyapatite.
Karl KruszelnickiHOST
It sounds like appetite when you're hungry, but it's spelled differently, A-P-A-T-I-T-E.
Karl KruszelnickiHOST
And that makes it hard and gives it compressive strength.
Karl KruszelnickiHOST
And then there are cells, living cells and blood vessels, and your bones are continuously being destroyed and rebuilt.
Eric BergHOST
In the past we could never find these things, but deep inside these kidney stones there are microbes, and they're nanobacteria.
Eric BergHOST
And it just so happens that these nanobacteria eat calcium and then form bone-like crystal structures, and that is called apatite, but it's a completely different definition of when you have an appetite for food, okay? Apatite is a type of calcium phosphorus that is in bone, okay? And these nanobacteria actually make this type of calcium as an igloo-type structure to help them survive against various stresses like antibiotics.
Eric BergHOST
Antibiotics are a drug that kills bacteria, and one of the big side effects of antibiotics is enhanced microbial biofilms.
Eric BergHOST
And biofilms are these colonies of microbes with these little calcium igloo-type protective shells.
