BY4005 Advances in Molecular Pathogenesis Syllabus – Anna University PG Syllabus Regulation 2021

COURSE OBJECTIVES:

1 To know about the host pathogen interaction and identifying virulence factors involved in viral
pathogenesis
2 To educate about vaccine development and functional genomic approaches in treatment of
fungal pathogenesis
3 To provide depth knowledge in clinical significance in bacterial pathogenesis treatments
4 To understand about the microbial toxins and modern molecular pathogenesis
5 To control pathogens by modern approaches.

UNIT I VIRAL PATHOGENESIS
Various pathogen types and modes of entry – Viral dissemination in the host – Viral virulence – Injury induced by virus – Host susceptibility of viral disease – Pattern of infection – Acute infection – Persistant infection – Latent infection – Slow infection – Methods for the study of pathogenesis – Foot and mouth disease virus, Pestiviruses, Arteriviruses, Blue tongue virus and Animal herpesviruses

UNIT II FUNGAL PATHOGENESIS

Innate humoral immunity to fungi – Acquired cellular immunity – Mucosal immunity – Intracellular pathogenesis of Histoplasma capsulatum – Facultative intracellular pathogen of Cryptococcus neoformans – Fungal interaction with leukocytes – Fungal vaccine development – Host defence against chronic disseminated Candidiasis – Study fungal virulence by using Genomics – Functional genomic approaches to fungal pathogenesis.

UNIT III BACTERIAL PATHOGENESIS

Epidemology and Clinical disease – Clinical course and basic immunology – In vitro models of Salmonella virulence – Antibiotic resistant Salmonella – Salmonella based vaccines – Shigella cellular models of infection – Influenza virus – Pathogenic Escherichia coli – Vibrio cholerae – Streptococcal disease – Haemophilus influenzae infection.

UNIT IV MANIPULATION OF HOST CELLS AND IMMUNE FUNCTION BY VIRAL PROTEINS

Clinical importance of understanding host defence – Interference with cytokine and Chemokine function – impairment of host mediated killing of infected cells – inhibition of apoptosis – Immunological structure of proteins – Class I and II MHC mediated antigen – Evasion from natural killer cells.

UNIT V MOLECULAR APPROACHES TO CONTROL

Classical approaches based on serotyping – Modern diagnosis based on highly conserved virulence factors, immune and DNA based techniques – New therapeutic strategies based on recent findings on molecular pathogenesis – Viral Vaccines – Immune modulators – New vaccine technology.
