Download or read book The New Microbiology written by Pascale Cossart and published by John Wiley & Sons. This book was released on 2020-07-10 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microbiology has undergone radical changes over the past few decades, ushering in an exciting new era in science. In The New Microbiology, Pascale Cossart tells a splendid story about the revolution in microbiology, especially in bacteriology. This story has wide-ranging implications for human health and medicine, agriculture, environmental science, and our understanding of evolution. The revolution results from the powerful tools of molecular and cellular biology, genomics, and bioinformatics, which have yielded amazing discoveries, from entire genome sequences to video of bacteria invading host cells. This book is for both scientists and especially nonscientists who would like to learn more about the extraordinary world of bacteria. Dr. Cossart's overview of the field of microbiology research, from infectious disease history to the ongoing scientific revolution resulting from CRISPR technologies, is presented in four parts. New concepts in microbiology introduces the world of bacteria and some recent discoveries about how they live, such as the role of regulatory RNAs including riboswitches, the CRISPR defense system, and resistance to antibiotics. Sociomicrobiology: the social lives of bacteria helps us see the new paradigm by which scientists view bacteria as highly social creatures that communicate in many ways, for example in the assemblies that reside in our intestine or in the environment. The biology of infections reviews some of history's worst epidemics and describes current and emerging infectious diseases, the organisms that cause them, and how they produce an infection. Bacteria as tools introduces us to molecules derived from microbes that scientists have harnessed in the service of research and medicine, including the CRISPR/Cas9 genome-editing technology. The New Microbiology takes us on a journey through a remarkable revolution in science that is occurring here and now.

Download or read book Advances in microbial food safety written by J. Chen and published by Elsevier Inc. Chapters. This book was released on 2013-07-31 with total page 31 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent advances regarding the human foodborne pathogen Listeria monocytogenes are discussed with specific emphasis on epidemiology, ecology and virulence. Recent routine surveillance and outbreak investigation studies indicate a shift in L. monocytogenes serotypes linked to listeriosis in some countries. There is growing evidence to show that L. monocytogenes isolates can be divided beyond the serotype level into at least two epidemiologically and genetically distinct subpopulations differentiated by biologically meaningful markers, including strains responsible for the majority of listeriosis cases and strains carrying virulence attenuating mutations in the key virulence gene inlA, which codes for internalin A.

Download or read book Characterization of Novel Virulence Factors of Listeria Monocytogenes and Their Roles in Pathogenesis written by Ting Zhang and published by . This book was released on 2013 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: The pathogenicity of food-borne intracellular bacterium Listeria monocytogenes is greatly associated with its abilities to invade non-phagocytic cells, counteract the host innate immune system, resist bactericidal antibiotic-mediated killing, and breaking the physical barriers. In the last 30 years of research on L monocytogenes, several virulence factors, such as Listeriolysin O (LLO), InlA, InlB, ActA, PI-PLC, and PC-PLC have already been characterized as important players that help this bacterium to achieve the key stage of infection. There are approximately 3,000 open reading frames in Listeria's genome; however, only few virulence factors are functionally characterized. Thus, it is important to identify new virulence factors and understand how new virulence factors in Listeria help this opportunistic pathogen to counteract the host innate immune system, resist antibiotic-mediated killing, colonize vital organs, and finally successfully develop life-threatening listeriosis. In this study, in-frame deletion mutagenesis was used to generate the deletion mutants of novel listerial virulence factors and a series of biochemical, in vitro and in vivo experiments were conducted to characterize the roles of these virulence factors during the infection process. In the first part of this study, an A̲lkD̲-l̲ike p̲rotein (Adlp, LmoF2365_0220) was identified and the protein is associated with oxidant tolerance and aminoglycoside antibiotic resistance. In the second part of this study, a new internalin-like protein (LmoH7858_0369) was shown to be involved in invasion of Hep-G2 cells and organ colonization in mice. The third part of this study showed that listeriolysin O (LLO) mediates cytotoxicity on brain endothelial cells, suggesting that LLO may contribute to the invasion of the central nervous system by L monocytogenes. In summary, we identified and characterized two novel virulence factors, Adlp and LmoH7858_0369 that contributed to bacterial infection and revealed a new invasion mechanism of CNS cells that is mediated by LLO. Results from these studies provide a better understanding on the pathogenicity of L monocytogenes and can be used as therapeutical targets or vaccine candidates.

Download or read book Molecular Mechanisms of Bacterial Infection via the Gut written by Chihiro Sasakawa and published by Springer Science & Business Media. This book was released on 2009-10-08 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our gut is colonized by numerous bacteria throughout our life, and the gut epithelium is constantly exposed to foreign microbes and dietary antigens. Thus, the gut epithelium acts as a barrier against microbial invaders and is equipped with various innate defense systems. Resident commensal and foreign invading bacteria interact intimately with the gut epithelium and can impact host cellular and innate immune responses. From the perspective of many pathogenic bacteria, the gut epithelium serves as an infectious foothold and port of entry for disseminate into deeper tissues. In some instances when the intestinal defense activity and host immune system become compromised, even commensal and opportunistic pathogenic bacteria can cross the barrier and initiate local and systematic infectious diseases. Conversely, some highly pathogenic bacteria, such as those highlighted in this book, are able to colonize or invade the intestinal epithelium despite the gut barrier function is intact. Therefore, the relationship between the defensive activity of the intestinal epithelium against microbes and the pathogenesis of infective microbes becomes the basis for maintaining a healthy life. The authors offer an overview of the current topics related to major gastric and enteric pathogens, while highlighting their highly evolved host (human)-adapted infectious processes. Clearly, an in-depth study of bacterial infectious strategies, as well as the host cellular and immune responses, presented in each chapter of this book will provide further insight into the critical roles of the host innate and adaptive immune systems and their importance in determining the severity or completely preventing infectious diseases. Furthermore, under the continuous threat of emerging and re-emerging infectious diseases, the topic of gut-bacteria molecular interactions will provide various clues and ideas for the development of new therapeutic strategies.
