Bacteriology Research 

The bacteriology research faculty of the Department of Pathobiological Sciences investigates a wide variety of bacterial species and their hosts.  Research projects include the following bacteria: Anaplasma species, Brucella species, Ehrlichia species, Mycobacterium species, Rickettsia species, Bartonella henselae, Borrelia burgdorferi, Edwardsiella ictaluri, Flavobacterium columnare, Helicobacter hepaticus, Klebsiella pneumoniae, Legionella pneumophila, Photobacterium damselae, Streptococcus pneumoniae, Staphylococcus aureus, and E. coli O157:H7. Molecular mechanisms are used by the group to identify virulence factors, pathogenicity islands, diagnostic tools and vaccine candidates to aid in the eventual control, clearance, or eradication of these bacterial pathogens.
