The research activities in this department are as follows; classification, identification, serotyping and molecular typing of pathogenic bacteria described below for the diagnosis and investigation of community- and hospital- acquired bacterial infections. Molecular analysis of virulence of such bacteria has been intensively made, which outcomes are applied to the development of new methods for early diagnosis, and effective treatment and prevention.

Research on molecular genetics of enteric pathogenic bacteria such as enterohemorrhagic Escherichia coli and Campylobacter spp.
Development of molecular epidemiological methods for outbreak investigations of enteric pathogenic bacteria.
Research on molecular interaction of enteric pathogenic bacteria with host cells.
LABORATORY OF ENTERIC INFECTION II
Classification, identification, serotyping and etiology of family of Vibrionaceae and Shigella.
