Long-s doctrin holds that we are protected from fungi not just by layered immune defenses but ( e ) we are mammals*, with core temperatures higher than fungi prefer. The cooler outer surfaces of our bodies are at risk of minor assaults-think of athlete's foot*, yeast infections, ringworm*-but in people with healthy immune systems, invasive* infections have been ( f ). That may have left us overconfident. "We have an enormous (g) spot," says Arturo Casadevall, a physician and molecular microbiologist at the Johns Hopkins Bloomberg School of Public Health. "Walk into the street and ask people what are they afraid of, and they'll tell you they're afraid of bacteria, they're afraid of viruses, but they don't fear dying of fungi." Ironically, it is our successes that made us vulnerable*. Fungi exploit damaged immune systems, but before the mid-20th century people with impaired immunity didn't live very long. Since then, medicine has gotten very good at keeping such people (h), even though their immune systems are compromised by illness or cancer treatment or age. It has also developed an array of therapies that deliberately suppress immunity, to keep transplant recipients healthy and treat autoimmune* disorders such as lupus* and rheumatoid arthritis*. ( i ) vast numbers of people are living now who are especially vulnerable to fungi. Not all of our vulnerability is the fault of medicine preserving life so successfully. Other ( j ) actions have opened more doors between the fungal world and our own. We clear land for crops and settlement and perturb* what were stable balances between fungi and their hosts. We carry goods and animals across the world, and fungi hitchhike on them. We drench crops in fungicides* and enhance the resistance of organisms residing nearby. (s) ELSE
