Microbes are everywhere – and they aren't all friendly. Jerry Malayer , Oklahoma State University There are about 1,400 known human pathogens – viruses, bacteria, fungi, protozoa and helminths that can cause a person's injury or death. But in a world with a trillion individual species of microorganisms , where scientists have counted only one-thousandth of one percent , how likely is it researchers have discovered and characterized everything that might threaten people? Not very likely at all. And there's a lot to be gained from knowing these microscopic enemies better. So even though in day-to-day life it makes sense to avoid these dangerous microorganisms, scientists like me are motivated to study them up close and personal to learn how they work. Of course, we want to do it in as safe a way as possible. I've worked in biocontainment laboratories and have published scientific articles on both bacteria and viruses, including influenza and the SARS-CoV-2 coronavirus . Here at Oklahoma State University, 10 research groups are currently studying pathogens in biosecure labs. They're identifying genetic variations of viruses and bacteria, studying how they operate within cells of their hosts. Some are untangling how the host immune system responds to… Read full this story
