Bacterial Pathogenesis And Antibacterial Control

Bacterial pathogens have been becoming the main problem in hospital and community-acquired infections. It is hard to treat the strains that are resistant to antibiotics, due to the causing recurrent and untreatable infections. In recent years, the combination treatments and the novel technologies have been preferred to overcome the emergence of antibacterial resistance of pathogens. In this book, examples of pathogenesis by clinical cases, control by antibiotics and bioactive antimicrobials, control by novel technologies with the collection of up-to-date researches and reviews are presented. This book can be useful for researchers interested in antibacterials, bioactive compounds, and novel technologies.

Bacterial infections affect world health today as a leading cause of morbidity and mortality. This book presents in-depth methods and state-of-the-art protocols for investigating specific mechanisms of pathogenesis for a wide range of bacteria. Written by experts in the field, this invaluable collection includes protocols to study host-pathogen interactions, animal models of infection, and novel approaches to identifying therapeutic targets designed to control infections.

Pathogenic bacteria are the main problem in hospital- and community-acquired infections. As bacteria continue to develop more resistance to antibiotics, it is imperative to develop antibacterial treatment strategies. Written by experts from all over the world, this book examines pathogenic bacteria and their link to multidrug resistance. Over thirteen chapters, it presents examples of pathogenesis, virulence factors, and treatment strategies.

Humans coexist with millions of harmless microorganisms, but emerging diseases, resistance to antibiotics, and the threat of bioterrorism are forcing scientists to look for new ways to confront the microbes that do pose a danger. This report identifies innovative approaches to the development of antimicrobial drugs and vaccines based on a greater understanding of how the human immune system interacts with both good and bad microbes. The report concludes that the development of a single superdrug to fight all infectious agents is unrealistic.

"Although most forms of bacteria are harmless, pathogenic bacteria can cause disease and as such these microorganisms warrant scientific attention. Chapter One describes the virulence problem caused by extracellular polymeric substances and antibacterial compounds capable of inhibiting their production, biofilm formation, and bacterial pathogenicity. Chapter Two provides an overview of biophysical techniques that can validate targets of phytochemicals with anti-virulence properties that can help elucidate their mode of action. Chapter Three discusses terpenes' anti-virulence modes of action, inhibition of biofilm, disruption of the cell wall and bacterial membrane, intercellular leakage, interruption of nucleic acids transcription, and interference with the quorum sensing signaling process. Chapter Four investigates the anti-pathogenic potential of essential oil from the plant asafoetida obtained through microwave-assisted extraction method. Finally, Chapter Five deals with the effect of audible sound waves on bacteria"--
