About BGP

The Bacterial Genetics and Pathogenesis Group (BGP) at the University of Massachusetts Medical School is an interdisciplinary group of faculty interested in basic biological processes such as DNA repair, recombination and transcription in Escherichia coli  K-12 as well as the molecular basis of microbial pathogenesis. The pathogenic bacteria under investigation include enterohemorrhagic (EHEC) and enteropathogenic (EPEC) Escherichia coliPseudomonas aeruginosa, the plague bacillus Yersinia pestis,Haemophilus influenzae , Listeria monocytogenesMycobacterium tuberculosis and the Borrelia  species causing Lyme disease and Relapsing Fever.
