Bacterial Pathogenesis is nothing but the origin of a disease through bacteria, while virulence is, the ability of infectious agent to produce a disease and countermeasure is an action that counters infectious agents. Countermeasures for gram-negative and gram-positive bacterial infections involve biofilms. Colonies of bacteria live in a biofilm made up principally of capsule material. Antimicrobials in tandem with chemical compounds are good in combating biofilms. Molecular targets of bacterial virulence proteins important for developing plant disease are still unclear. Yet bacterial surface component plays an important role in the pathogenesis of infectious disease. The ability of the organism to cause disease despite host resistance mechanisms directly depends on the degree of virulence. Of late, the number of new antibacterial drugs has plummeted while the number of antibiotic-resistant infections has risen. As a result, there is every need to develop newer drugs to counter infectious diseases. This session discusses in detail about what measures need to be taken to develop newer drugs to counter bacterial pathogenesis of infectious diseases. The latest trends in research, the latest technologies available, the application of robotics and nanotechnology in developing countermeasures to counter pathogenesis of infectious diseases demands the attention Pathologists, Microbiologists, Bacteriologists, Parasitologists, Virologists, and immunologists etc.
