The Third International Conference on Haemophilus, Actinobacillus, and Pasteurella (HAP94) was held in July and August at the Edinburgh Conference Centre, Heriot-Watt University, Riccarton Campus, Edinburgh, Scotland, UK. Previous conferences in 1981, Copenhagen, and 1989, Guelph, had indicated widespread interest in this group of pathogenic bacteria and the timing of the Edinburgh conference was prompted by the major advances in our knowledge of the HAP group that had occurred in the five years since the Guelph meeting. These organisms are considered as a group because of their close relationship in an evolutionary sense and because of the similarities in the types of diseases that they preduce. The main objectives of the meeting were to review and discuss current knowledge and present experimental findings relating to the fundamental, applied, clinical, and therapeutic aspects of disease research involving the HAP group of organisms. HAP 94 was attended by 160 delegates from around the world and included many of the foremost researchers studying HAP organisms. The conference was structured around 16 talks from invited speakers who covered key areas of HAP research including taxonomy, mechanisms of pathogenesis, animal disease models, virulence factors, molecular biology, immunolgy, antigen analyses, and experimental and commercial vaccine development. The talks provided a review of the current state of research in each field and allowed each speaker to focus on his or her personal research interests.

This book focuses on the multitude of functions bacterial membrane vesicles perform in bacterial ecology and pathogenesis as well as in emerging medical and biotechnological applications. Both Gram-negative and Gram-positive bacteria produce membrane-bound nanostructures, known as membrane vesicles, which have a range of functions that include serving as delivery vehicles, providing a means of communication over both spatial and temporal scales, and contributing to bacterial survival and evolution. Topics covered in this book range from the biogenesis and composition of bacterial membrane vesicles to their abundance and biological roles in microbial ecosystems, such as marine environments. In the individual chapters, the involvement of bacterial membrane vesicles in host-pathogen interactions, promoting virulence and in facilitating the establishment of infection is explained. In addition, current knowledge regarding membrane vesicles produced by commensal bacteria and their role in the maturation of the host immune system, as well as the therapeutic potential of bacterial membrane vesicles as delivery systems and innovative nanotechnology-based therapeutics are discussed. This work appeals to a wide readership of students and researchers interested in microbial ecology, mechanism underlying pathogenesis and new avenues in applied microbiology and nanotechnology.

Magnetotactic bacteria (MTB) synthesize intracellular nano-sized minerals of magnetite and/or greigite magnetosomes for magnetic orientation. They play important roles in global iron cycling and sedimentary magnetism, and have a broad range of potential applications in both biotechnological and biomedical fields. However, because the majority of MTB in nature remain unculturable, our understanding of these specific bacteria remains fairly limited. This thesis describes the development of a novel approach for effectively collecting, purifying and characterizing uncultivated magnetotactic bacteria. The diversity, genomic information and rock magnetic properties of various uncultivated MTB are investigated and characterized using a combination of biological and geophysical methods. The results will lead to a better understanding of the biogeography and biomineralization mechanisms of MTB in nature, and improve our knowledge of the contributions of MTB to biogeochemical cycles of elements and sedimentary magnetism.

One of the most exciting developments in the field of bacterial pathogenesis in recent years is the discovery that many pathogens utilize complex nanomachines to deliver bacterially encoded effector proteins into eukaryotic and prokaryotic target cells to modulate a variety of cellular functions for the pathogen's benefit. These protein-delivery machines include the type III secretion system (T3SS), which is widespread in nature and encoded not only by bacteria pathogenic to vertebrates or plants, but also by bacteria that are symbiotic to plants or insects. Because they are essential virulence factors for many important human pathogens, these systems are emerging as a prime target for the development of new-generation, anti-infective drugs. This book reviews our current understanding of these intriguing injection machines as well as of the closely related T3SS that serves in flagella assembly. Individual chapters focus on regulation, assembly, structure, and function of the type III secretion machine and on the evolution of the secreted effector proteins. Given its scope, this book will appeal to a broad readership, including researchers and teachers in the fields of infectious diseases, host pathogen interactions, plant and animal pathogenesis, and symbiosis.

During the last decade, research on Pseudomonas syringae pathovars and related pathogens has progressed rapidly, opening up many new avenues. The application of molecular genetics has provided new insights into determinants of pathogenicity and virulence. Progress has also been made in elucidating the chemical structures and modes of action of phytotoxins from Pseudomonas syringae; by establishing novel strategies for disease control; in biotechnological applications; by studying the resistant reaction of the plant with a combined biochemical and genetic approach; and in the development of new detection and identification methodologies as tools in epidemiological studies. With such rapid advances it becomes more and more difficult to keep abreast of the developments and concepts within disciplines, all involving research on pathovars of P. syringae. In an attempt to provide a balanced overview, recent developments in these rapidly expanding fields have been critically reviewed at the beginning of each chapter by internationally renowned experts. Our comprehensive coverage has been made possible because all the contributors to this volume presented their latest findings at the `5th International Conference on Pseudomonas syringae Pathovars and Related Pathogens' in Berlin, September 3-8, 1995. In this way, it was possible to bring together contributions from a wide range of fields including phytopathology, genetics, bacteriology, plant breeding, plant protection, and taxonomy. This book is not intended simply as a record of the proceedings of the Berlin Conference, but as an extension of recent findings and hypotheses put forward at the meeting. All papers published in this volume have been reviewed by the Editors.

Drug-resistant bacteria ― known as superbugs ― are one of the biggest medical threats of our time. Here, a doctor, researcher, and ethics professor tells the exhilarating story of his race to beat them and save countless lives.

When doctor Matt McCarthy first meets Jackson, a mechanic from Queens, it is in the ER, where he has come for treatment for an infected gunshot wound. Usually, antibiotics would be prescribed, but Jackson’s infection is one of a growing number of superbugs, bacteria that have built up resistance to known drugs. He only has one option, and if that doesn’t work he may lose his leg or even his life.

On the same day, McCarthy and his mentor Tom Walsh begin work on a groundbreaking clinical trial for a new antibiotic they believe will eradicate certain kinds of superbugs and demonstrate to Big Pharma that investment in these drugs can save millions of lives and prove financially viable. But there are seemingly endless hoops to jump through before they can begin administering the drug to patients, and for people like Jackson time is in short supply.

Superbugs is a compelling tale of medical ingenuity. From the muddy trenches of the First World War, where Alexander Fleming searched for a cure for soldiers with infected wounds, to breakthroughs in antibiotics and antifungals today that could revolutionise how infections are treated, McCarthy takes the reader on a roller-coaster ride through the history ― and future ― of medicine. Along the way, we meet patients like Remy, a teenage girl with a dangerous and rare infection; Donny, a retired firefighter with a compromised immune system; and Bill, the author’s own father-in-law, who contracts a deadly staph infection. And we learn about the ethics of medical research: why potentially life-saving treatments are often delayed for years to protect patients from exploitation.

Can McCarthy get his trial approved and underway in time to save the lives of his countless patients infected with deadly bacteria, who have otherwise lost all hope?

The aim of this book is to provide readers with a wide overview of the main healthcare-associated infections caused by bacteria and fungi able to grow as biofilm.

For the eighth time the yersiniologists all over the world gathered together when the International Symposium on Yersinia was organized by University of Turku and Turku Microbiology Society in Turku, Finland. Over 250 delegates from 28 countries attended the Symposium. The Symposium logo (Picture 4, next page) presents a bacteriophage attached to the surface of the bacterium. One can easily imagine that most of the aspects covered in this Symposium are included in the logo: the bacteriophage genome encodes for structural proteins, adhesins and effector proteins that interact with the host cell in most intricate ways to carry out their mission. Life of the bacteriophage depends on the tightly regulated interplay between the phage and the host proteins. This all is also true between Yersinia and the different hosts and environments it encounters during its life cycle. This Symposium Proceedings volume is based on the oral and poster presentations given during the Symposium. The volume has been divided into six parts covering topics such as genomics, surface structures, bacteriophages, molecular and cellular pathogenesis, molecular epidemiology and diagnostics, gene regulation, clinical aspects and vaccines. These topics reflect righteously the present trends in the bacteriology research.
