Microbiology has gotten really cool of late. For years, nobody could get some species of bacteria that are naturally found in our bodies to grow in culture. It was recently discovered that some of these bacteria need different species of bacteria to grow, presumably whose waste products they need to survive. So we have a situation where the bacteria need each other, and we need them. It's fascinating. Always remember, 90% of the cells you carry on you aren't human cells.
