Book Description
Francisella tularensis, the causative agent of tularemia, is a paradigm among human pathogens. This Gram-negative bacterium has an intracellular lifestyle, which probably reflects an adaptation to its natural animal and protozoa reservoirs. This is one of the most infectious agents in humans and animals; only a few bacteria are needed to induce a severe infection in both types of hosts. The clinical presentation and severity of human tularemia varies according to the portal of entry of bacteria, the bacterial inoculum, the virulence of the infecting strain, and the immune response of the host. Although most infections occur after direct inoculation of bacteria through the skin (through skin wounds or bites of arthropods), pneumonia due to inhalation of infected aerosols is the most feared of the clinical forms of the disease, particularly in the context of biological threat. Two subspecies are responsible for tularemia (subsp. tularensis and subsp. holarctica), and several clades have been described for each, which might be associated with changes in disease severity in humans. Tularemia is also more severe in people with an impaired immune response. No safe vaccine is currently available for prophylaxis of tularemia in humans. On the other hand, control of proliferation of F. tularensis in wildlife is not feasible. Thus, only the anti-infective agents are used for treatment and prophylaxis of human tularemia. The standard options include aminoglycosides (gentamicin), tetracyclines (eg, doxycycline) and fluoroquinolones (eg, ciprofloxacin). The selection of acquired resistance to these antibiotics in F. tularensis, especially in the context of a biological threat, may quickly limit the therapeutic options. New prophylactic and therapeutic alternatives must be developed rapidly. The present Research Topic focuses on potential new strategies for treatment of tularemia, including the development and evaluation of new compounds having proper antibacterial activity, reducing the virulence of F. tularensis or enhancing the immune host response.

Book Description
Tularaemia is a bacterial zoonotic disease of the northern hemisphere. The bacterium (Francisella tularensis) is highly virulent for humans and a range of animals such as rodents hares and rabbits. Humans can infect themselves by direct contact with infected animals by arthropod bites by ingestion of contaminated water or food or by inhalation of infective aerosols. There is no human-to-human transmission. In addition to its natural occurrence F. tularensis evokes great concern as a potential bioterrorism agent. F. tularensis subspecies tularensis is one of the most infectious pathogens known in human medicine. In order to avoid laboratory-associated infection safety measures are needed and consequently clinical laboratories do not generally accept specimens for culture. However since clinical management of cases depends on early recognition there is an urgent need for diagnostic services. This first edition of WHO Guidelines on tularaemia provides background information on the disease describes the current best practices for its diagnosis and treatments in humans suggests measures to be taken in case of epidemics and provides guidance on how to handle F. tularensis in the laboratory. The target audience includes clinicians laboratory personnel public health workers veterinarians and any other person with an interest in zoonoses.

Book Description
Anti-infective agents are a distinct class of pharmacologically important molecules that have served mankind in different capacities to combat life-threatening pathological conditions. They include antibacterial, antifungal, antiviral, antituberculosis, antimalarial, and urinary anti-infective agents. However, evolutionary changes, adaptations, and the development of new strains of pathogenic microorganisms have reduced the therapeutic efficacy of existing drugs, thus, limiting their clinical utility over the years. Frontiers in Anti-Infective Agents Volume 6 is a collection of notable research efforts, successful anti-infective drug development programs, and a comprehensive overview of successful and unsuccessful clinical trials conducted in this domain. This volume continues from the last one with interesting reviews on 1) “Reverse Vaccinology” for vaccination design using computational data to identify vaccine targets, 2) leptospirosis, 3) phage therapy for bacterial infections, 4) quorum sensing inhibitors from natural products, and 5) nitrogen and oxygen-based heterocyclic compounds that can act as anti-infective agents. The volume, therefore, covers a range of frontier topics on anti-infective research and development. This compilation is a timely reference for postgraduate scholars and researchers seeking updates in specific areas of anti-infective drug development. Allied healthcare professionals (clinical and public healthcare professionals) can also benefit from the information presented within.

Book Description
If terrorists released Bacillus anthracis over a large city, hundreds of thousands of people could be at risk of the deadly disease anthrax-caused by the B. anthracis spores-unless they had rapid access to antibiotic medical countermeasures (MCM). Although plans for rapidly delivering MCM to a large number of people following an anthrax attack have been greatly enhanced during the last decade, many public health authorities and policy experts fear that the nation's current systems and plans are insufficient to respond to the most challenging scenarios, such as a very large-scale anthrax attack. The U.S. Department of Health and Human Services' Office of the Assistant Secretary for Preparedness and Response commissioned the Institute of Medicine to examine the potential uses, benefits, and disadvantages of strategies for repositioning antibiotics. This involves storing antibiotics close to or in the possession of the people who would need rapid access to them should an attack occur. Prepositioning Antibiotics for Anthrax reviews the scientific evidence on the time window in which antibiotics successfully prevent anthrax and the implications for decision making about prepositioning, describes potential prepositioning strategies, and develops a framework to assist state, local, and tribal public health authorities in determining whether prepositioning strategies would be beneficial for their communities. However, based on an analysis of the likely health benefits, health risks, and relative costs of the different prepositioning strategies, the book also develops findings and recommendations to provide jurisdictions with some practical insights as to the circumstances in which different prepositioning strategies may be beneficial. Finally, the book identifies federal- and national-level actions that would facilitate the evaluation and development of prepositioning strategies. Recognizing that communities across the nation have differing needs and capabilities, the findings presented in this report are intended to assist public health officials in considering the benefits, costs, and trade-offs involved in developing alternative prepositioning strategies appropriate to their particular communities.

Book Description
This volume provides an excellent survey of the chemistry, microbiology, pharmacology and clinical use of the oral cephalosporins in general and the newer agents in particular. The cephalosporins have long provided satisfactory treatment for many disorders without causing serious side effects; and over the past fifty years forms with different antimicrobial, pharmacologic and toxicologic properties have been developed. Despite the broad spectrum of their activity against a large variety of gram-positive and gram-negative bacteria, the third-generation oral cephalosporins including the prodrug esters do not work against Pseudomonas aeruginosa, methicillin-resistant staphylococci, enterococci or Bacteroides species. Many, however, are suitable for treating infections of the respiratory and urinary tracts and of the skin and its structure, as well as certain sexually-transmitted diseases. Authors consider other possible uses, against multi-resistant Enterobacteriaceae for instance, but also point out the limitations of the oral cephalosporins. For those working in the fields of infectious disease, bacteriology, chemotherapy, pharmaceutics and pharmacokinetics, this book is a valuable source of authoritative information.
