Book Description
The use of model antigens such as haptens and ovalbumin has provided enormous insights into how immune responses develop, particularly to vaccine antigens. Furthermore, these studies are overwhelmingly performed in animals housed in clean facilities and are not known to have experienced overt clinical signs caused by infectious agents. Therefore, this is unlikely to reflect the impact more complex host-pathogen interactions can have on the host, nor the diversity in how immunity is regulated. Humans develop immune responses in the context of the periodic exposure to multiple pathogens and vaccines over a life-time. These are likely to have a long-lasting effect on who and what we are and how we respond to further antigen challenge. Therefore, studies on how infection influences immune homeostasis and how the development of responses to a pathogen reflects what is known on immune regulation will be informative on how we can translate findings from our standard models into treatments usable in humans.
One organism allows us to do just this. Bacteria of the genus Salmonella are devastating human pathogens. Nevertheless, many aspects of the diseases they cause can be successfully modelled in murine systems so that the infection is either resolving or non-resolving. This has the advantage of allowing the long-term impact of infection on immune function to be assessed. We propose to welcome key workers to write about their research that examine the consequence of Salmonella infection on the host and the elements of the bacterium that contribute to this.

Book Description
This key work in the field draws on a broad spectrum of molecular biologic, biochemical, and immunogenetic approaches in combination with human and murine in vitro cell culture and in vivo model systems to address questions in mucosal immunity. Humans produce more immunoglobulin A (IgA) than all other antibody isotypes combined. This book is designed to serve as a concise reference of the present knowledge of the biology of IgA.

Book Description
An examination of persistent bacterial infections in the light of ecological and evolutionary principles. - Focuses on the principles of parasitism and commensalism and our ability to distinguish the two states. - Explores the ways in which persistent infections differ from acute, self-limiting bacterial infections and how both differ from the nonpathogenic commensal state. - Addresses coevolution, host adaptation, natural selection, and other fundamental biological principles. - Serves as a resource for investigators and advanced students in the field of bacterial pathogenesis.

Book Description
Every aspect of immune function and host defense is dependent upon a proper supply and balance of nutrients. Severe malnutrition can cause significant alteration in immune response, but even subclinical deficits may be associated with an impaired immune response, and an increased risk of infection. Infectious diseases have accounted for more off-duty days during major wars than combat wounds or nonbattle injuries. Combined stressors may reduce the normal ability of soldiers to resist pathogens, increase their susceptibility to biological warfare agents, and reduce the effectiveness of vaccines intended to protect them. There is also a concern with the inappropriate use of dietary supplements. This book, one of a series, examines the impact of various types of stressors and the role of specific dietary nutrients in maintaining immune function of military personnel in the field. It reviews the impact of compromised nutrition status on immune function; the interaction of health, exercise, and stress (both physical and psychological) in immune function; and the role of nutritional supplements and newer biotechnology methods reported to enhance immune function. The first part of the book contains the committee's workshop summary and evaluation of ongoing research by Army scientists on immune status in special forces troops, responses to the Army's questions, conclusions, and recommendations. The rest of the book contains papers contributed by workshop speakers, grouped under such broad topics as an introduction to what is known about immune function, the assessment of immune function, the effect of nutrition, and the relation between the many and varied stresses encountered by military personnel and their effect on health.

Book Description
Salmonella infections of man and animals continue to be a distressing health problem worldwide. Far from disappearing, the incidence of typhoid fever in developing countries may be far higher than we had imagined. Salmonella food poisoning has increased to one of the major causes of gastroenteritis in the developed world, in itself also an indication that animal salmonellosis is still a major cause for concern. The situation requires a concerted multidisciplinary research effort in order to generate the new information and technology needed to assist in the control of these diseases. This concept was the driving force behind the NATO Advanced Research Workshop on "Biology of Salmonella" held at Portorosa, Messina, Italy, May 11-15, 1992. With additional support from the University of Messina, Medeva Group Research (UK) and the Swiss Serum and Vaccine Research Institute, the meeting brought together epidemiologists, microbiologists, molecular biologists, immunologists and clinicians. All the participants were actively working on different but related aspects of Salmonella and salmonellosis, with most of the leading laboratories worldwide being represented. The workshop provided an excellent opportunity for interdisciplinary consultation; it is not often that the topic of Salmonella and salmonellosis is covered to such breadth and depth in one extended meeting. Keynote addresses by invited speakers were interspersed with offered papers, many by younger members of the scientific community, and this volume presents the collated manuscripts of the lectures and extended summaries of the offered papers.

Book Description
This book describes modern biophysical techniques that enable us to understand and examine dynamic processes of infection at the molecular level. Cutting-edge research articles, laboratory protocols, case studies and up-to-date reviews cover topics such as single-molecule observation of DNA replication repair pathways in E. coli; evolution of drug resistance in bacteria; restriction enzymes as barriers to horizontal gene transfer in Staphylococcus aureus; infectious and bacterial pathogen biofilms; killing infectious pathogens through DNA damage; bacterial surfaces in host-pathogen interactions; bacterial gene regulation by riboswitches; transcription regulation in enterobacterial pathogens; the bacterial flagellar motor; initial surface colonization by bacteria; Salmonella Typhi host restrictions; as well as monitoring proton motive force in bacteria; microbial pathogens using digital holography; mathematical modelling of microbial pathogen motility; neutron reflectivity in studying bacterial membranes; force spectroscopy in studying infection and 4D multi-photon imaging to investigate immune responses. The focus is on the development and application of complex techniques and protocols at the interface of life sciences and physics, which increase the physiological relevance of biophysical investigations.
