Uchida: They exhibit three different phenotype. One is pathogenic and the second type is germative and the third type that is very highly invasive structure called hypha. That's a really bad type and it could cause fungal infections such as yeast infection and it could be pretty dramatically could lead to death in the immune-compromised patients who have been through chemotherapy or people who have AIDS.
Narrator: Uchida and her colleagues are using a high-powered microscope at the Lawrence Berkeley National Laboratory to see well inside the structure of these cells and found that a new type of synthetic antibiotic called peptoids can treat this drug-resistant, invasive form of Candida.
