Unit I: 
Normal micro flora and factors responsible for pathogenesis

Classification of medically important micro organisms; Normal microbial flora of human body; role of the resident flora.

Entry of pathogens into the host; colonization and mechanism of bacterial adhesion establishment, spreading, tissue damage and anti-phagocytic factors; factors predisposing to infections, types of toxins and their structure; mode of action.
