The rise in the incidence of infections is caused by multi drug resistant (MDR) bacteria, it is essential to elucidate the basic mechanism of antibiotic resistance to discover effective methods for diagnosis and treatment of infections. The use of pathogen-specific probes offers a faster alternative for pathogen detection and could improve the diagnosis of infection. High resolution melting analysis techniques are useful for the detection of multi drug resistant pathogens. Rational Structural Based Drug Design is a common method to identify a lead compound and take it forward for further developments. This book provides information about recent strategies involved in the diagnosis and treatment of infections caused by MDR bacteria. The volume covers the use of molecular probes for the quantification of pathogenic bacteria, along with other techniques mentioned above. Chapters also cover the use of identification of novel drug targets from the Lipid A biosynthesis and also from quorum sensing mediated biofilm formation in MDR bacteria. Chapters also cover herbal alternatives for the treatment of MDR bacteria like the use of Cassia aungustifolia in treatment of various diseases. The reference is suitable for biomedical students, cellular and molecular biologists.
