The emergence of infectious disease rarely ends in the complete extinction of host species. Frequently, the level of virulence in a severe disease system shifts such that hosts and pathogens can persist in a shared environment. However, the mechanistic underpinnings of these transitions are not well understood. The lethal fungal disease known as amphibian chytridiomyocosis provides a compelling system to investigate such shifts in infectious disease dynamics. The pathogen that causes chytridiomycosis, Batrachochytrium dendrobatids (commonly called "Bd"), is renown for its ability spread rapidly into amphibian communities and cause extremely high levels of mortality in many different host species. However, some host species have survived initial...Read More

The Fall 2016 Biology Seminar Series continues with Sharon Stranford’s talk: The MAIDS model system: IL-10 and the role of immunosuppression in susceptibility to immunodeficiency
Sharon Stranford studies factors that influence the development of acquired immune deficiency. She and the undergraduate students who work in her research lab employ a mouse model of AIDS (MAIDS) in which some strains of mice develop immune deficiency following exposure to Murine Leukemia Virus (MuLV). This allows them to compare the early immune response patterns of MAIDS-susceptible and MAIDS-resistant mice for clues to immune pathways that bias towards resolution versus immunodeficiency. This is done using a combination of techniques, including comparative gene expression, flow cytometric analysis, enzyme-linked immunosorbant assays (ELISAs) and fluorescence microscopy.
