We have all heard about how the body contains more microorganisms than it does cells. The vast majority of these are friendly bacteria that help our body in its processes. However, less than 1% are bad bacteria that cause illness. For these, we use antibiotics to stomp them into submission (i.e., kill them). But since bacteria replicate so quickly, they often develop a genetic change that helps them avoid or fight off an antibiotic's effects.
So, microbiologists and immunologists have to constantly be on the look out for potential new drugs to fight off illness caused by bad microorganisms.
Check out this video where Professor Naowarat (Ann) Cheeptham, at Thompson Rivers University, talks about her research of exploring caves in the search for new species of "good" bacteria and fungi to produce new antibiotics. Who says scientists only stay in their labs? Go science!
