This Research Topic is dedicated to our current understanding of the molecular pathogenesis of Neisseria gonorrhoeae. Topics in this issue include the following: human infection models for testing gonococcal virulence, animal models that mimic lower female genital tract infection, and an ex vivo system derived from the human female lower genital tract. Vaccine development efforts, and the impact of gonococcal infection on the host's immune response are also described. Also part of this issue are reviews of the molecular aspects of several important virulence factors, including: biofilm formation, neutrophil resistance, innate immune factor resistance, iron acquisition, and type 4 secretion systems.
This important book provides research scientists, advanced students, clinicians, and other professionals with a comprehensive update on the current understanding of the molecular mechanisms of pathogenesis in Neisseria. Neisseria gonorrhoeae and Nesseria meningitidis are Gram-negative diplococci. N. gonorrhoeae is the causative agent of gonorrhoeae and is transmitted via sexual contact. N. meningitidis is transmitted via respiratory droplets leading to colonization of the nasopharynx and can cause meningitis and septicemia. The book describes the latest, up-to-date research, theory, and clinical significance of molecular mechanisms in meningococcal disease. Leading authorities have contributed chapters on topics such as gene expression, genomics, biofilms, denitrification, adhesion strategies, and mechanisms of cellular invasion. A section on the host response to neisserial infection covers inate immunity, complement, apoptosis, and acquired immunity, while a section devoted to clinical correlation deals with vaccine development, epidemiology, and antibiotic resistance. The book is highly recommended for microbiologists, epidemiologists, and clinicians involved with Neisseria research or meningococcal disease, and it is a recommended text for all microbiology libraries.
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.
Gonorrhea is a sexually transmitted infection caused by the obligate human pathogen“Neisseria gonorrhoeae”. This Gram-negative diplococcus is highly infective due to its virulence factors: pili, Por proteins, Opa proteins, Rmp proteins, lipooligosaccharides and IgA protease. Despite existing guidelines for its treatment, the incidence of the disease follows an increasing trend worldwide. This is mainly due to the appearance of antibiotic-resistant strains, inefficient diagnostic methods and poor sexual education. Without an effective vaccine available, the key priorities for the control of the disease include sexual education, contact notification, epidemiological surveillance, diagnosis and effective antibiotic treatment. This Special Issue focuses on some of these important issuesm such as the molecular mechanisms of the disease, diagnostic tests and different treatment strategies used to combat gonorrhea.
The molecular age has brought about dramatic changes in medical microbiology, and great leaps in our understanding of the mechanisms of infectious disease. Molecular Medical Microbiology is the first book to synthesise the many new developments in both molecular and clinical research in a single comprehensive resource. This timely and authoritative three-volume work is an invaluable reference source of medical bacteriology. Comprising more than 100 chapters, organized into 17 major sections, the scope of this impressive work is wide-ranging. Written by experts in the field, chapters include cutting-edge information, and clinical overviews for each major bacterial group, in addition to the latest updates on vaccine development, molecular technology and diagnostic technology. Topics covered include bacterial structure, cell function, and genetics; mechanisms of pathogenesis and prevention; antibacterial agents; and infections ranging from gastrointestinal to urinary tract, centrtal nervous system, respiratory tract, and more. - The first comprehensive and accessible reference on molecular medical microbiology - Full color presentation througout - In-depth discussion of individual pathogenic bacteria in a system-oriented approach - Includes a clinical overview for each major bacterial group - Presents the latest information on vaccine development, molecular technology, and diagnostic technology - More than 100 chapters covering all major groups of bacteria - Written by an international panel of authors who are experts in their respective disciplines
Bacteria form a fundamental branch of life. They are the oldest forms of life as we know it, and they are still the most prolific living organisms. They inhabit every part of the Earth's surface, its ocean depths, and even terrains such as boiling hot springs. They are most familiar as agents of disease, but benign bacteria are critical to the recycling of elements and all ecology, as well as to human health. In this Very Short Introduction, Sebastian Amyes explores the nature of bacteria, their origin and evolution, bacteria in the environment, and bacteria and disease. In looking at our efforts to manage co-evolving bacteria, he also considers the challenges of resistance to antibiotics. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.
