Past Bug Club
Spring 2012 Fall 2011 Spring 2011 Fall 2010

The Bug Club is a journal club within the Department of Microbiology and Immunology organized for the discussion of bacteriology related topics. The club format provides an informal setting for interested students and faculty to discuss and to critically evaluate papers from the current literature. Bug Club discussions may deal with any aspect of bacteriology. Historically, these have included a broad range of topics including bacterial physiology, metabolism, genetics, molecular biology, antibiotic resistance, or pathogenesis.
