Book Description
A comprehensive overview of recent advances, from current basic research and epidemiology, to novel therapeutic strategies and clinical management. Here, the leading scientists who have made major advances in the field provide up-to-date reviews and describe their current knowledge and concepts. As such, this is the first volume to summarize the implications of the meningococcus genome-sequencing project, emphasizing the novel strategies in vaccine development. Following a look at the history, the authors go on to treat the epidemiology of meningococcal disease, as well as the genetics, structure and function of virulence factors. Further chapters cover cross-talk between meningococci and host cells, genomics and immunobiology. The result is a standard handbook for all scientists working in the field. While aimed at advanced specialists in basic research, epidemiologists, public health workers, vaccine developers and clinicians, the book is equally appropriate as introductory reading for graduates embarking on their career in this field.

Book Description
Principles of Bacterial Pathogenesis presents a molecular perspective on a select group of bacterial pathogens by having the leaders of the field present their perspective in a clear and authoritative manner. Each chapter contains a comprehensive review devoted to a single pathogen. Several chapters include work from authors outside the pathogenesis field, providing general perspectives on the evolution, regulation, and secretion of virulence and determinants. Explains the basic principles of bacterial pathogenesis Covers diverse aspects integrating regulation, cellular microbiology and evolution of microbial disease of humans Discusses current strategies for the identification of virulence determinants and the methods used by microbes to deliver virulence factors Presents authoritative treatises of the major disease microorganisms

Book Description
The human pathogens Neisseria meningitidis and Neisseria gonorrhoeae are exquisitely adapted to life within the human mucosa, their only natural niche. N. meningitidis is the causative agent of rapidly transmissible meningitis and septic shock. Vaccines developed to control this pathogen can be rendered ineffective by the pathogen's ability to undergo antigenic variation. In contrast, there are no current vaccination prospects for N. gonorrhoeae, the causative agent of sexually transmitted gonorrhoea. Historically, infections caused by N. gonorrhoeae were treated with antibiotics. However, the recent advent of new strains with resistance to all known antibiotics is causing such treatment regimes to fail, necessitating the need for new and more effective control strategies. In this book, leading Neisseria authorities review the most important research on pathogenic Neisseria to provide a timely overview of the field. The topics covered include: the link between pathogenesis and important metabolic pathways * vaccine development * antibiotic resistance * transcriptomics of regulatory networks * regulatory small RNAs * interactions with neutrophils * advances in humanized mouse models. An essential guide for research scientists, advanced students, clinicians, and other professionals working with Neisseria, the book is a recommended text for all microbiology libraries.

Book Description
This dissertation describes detailed characterization of the gonococcal genetic island (GGI) and its encoded type IV secretion system (T4SS) as well as peptidoglycan fragment release by Neisseria meningitidis (meningococcus). The GGI was first found in N. gonorrhoeae (gonococcus). We screened 126 N. meningitidis isolates and found that 20% of strains carry the GGI. We identified five distinct GGI types in meningococci, two of which have similar T4SS-encoding regions to gonococci. Unlike the gonococcal T4SS, the meningococcal T4SS was not found to secrete DNA. The meningococcal GGI also has no effect on adherence, invasion, or iron uptake for intracellular survival, in cervical epithelial cells. Despite genetic similarities between the GGI in N. gonorrhoeae and N. meningitidis, the function of the GGI in meningococci remains unclear. Previous work showed that purified meningococcal peptidoglycan activates NF-[kappa]B through Nod1. We hypothesized that meningococci release peptidoglycan fragments during growth that induce an inflammatory response through Nod1. We observed meningococcal release of peptidoglycan dimers, monomers, free disaccharide, and two free peptide fragments. Recycling of peptidoglycan monomers was highly efficient (96%), which is more efficient than recycling in gonococci. Comparison of peptidoglycan fragment release by N. meningitidis and N. gonorrhoeae revealed that meningococci release less of the pro-inflammatory monomer and release additional, smaller dimer and monomer fragments. These data suggest that meningococci alter peptidoglycan fragment release by increasing recycling efficiency and degrading peptidoglycan fragments further. The variations in fragment release between the pathogenic Neisseria results in significantly less Nod1-dependent NF-[kappa]B activation by meningococcal supernatants. Decreasing inflammatory peptidoglycan release may be advantageous for N. meningitidis to maintain colonization of its human host. Meningococci were found to release two different free peptide fragments from the cell wall, and required the proteins AmiC and NlpD for this process. AmiC is an amidase that cleaves the bond between N-acetylmuramic acid and L-alanine and is required for cell separation. The putative endopeptidase NlpD was also required for cell separation. Mutation of amiC or nlpD had different effects on the release of peptidoglycan fragments. It is not clear whether NlpD enhances activity of AmiC, or if NlpD itself is capable of peptidoglycan degradation.

Book Description
Medical Microbiology Illustrated presents a detailed description of epidemiology, and the biology of micro-organisms. It discusses the pathogenicity and virulence of microbial agents. It addresses the intrinsic susceptibility or immunity to antimicrobial agents. Some of the topics covered in the book are the types of gram-positive cocci; diverse group of aerobic gram-positive bacilli; classification and clinical importance of erysipelothrix rhusiopathiae; pathogenesis of mycobacterial infection; classification of parasitic infections which manifest with fever; collection of blood for culture and control of substances hazardous to health. The classification and clinical importance of neisseriaceae is fully covered. The definition and pathogenicity of haemophilus are discussed in detail. The text describes in depth the classification and clinical importance of spiral bacteria. The isolation and identification of fungi are completely presented. A chapter is devoted to the laboratory and serological diagnosis of systemic fungal infections. The book can provide useful information to microbiologists, physicians, laboratory scientists, students, and researchers.
