Book Description
​This book explores the many mechanisms by which the most prevalent Spirochetal pathogens persist in a healthy immune-competent host. Among them are the direct and indirect suppression of host immune signals, phase and antigenic variation, escaping recognition by host complement proteins, and seclusion into immune privileged sites. We also explore antibiotic therapy for control of infection, a baffling topic that lends itself to exalted interpretation.

Book Description
Lyme disease (Lyme borreliosis) is the most prevalent vector-borne illness in the United States and Europe and a growing threat to global health. In addition Lyme disease is considered a model system of emerging infectious diseases. The book Borrelia: Molecular Biology, Host Interaction and Pathogenesis published in 2010 was the first state-of-the-art reference work covering the myriad, interlaced facets of the enzootic disorders caused by pathogenic Borrelia. This current volume, by the same editors, builds on the previous work and contains a vast amount of new information, a wider scope, and increased coverage of genomics, genetics, evolutionary biology, vector biology, physiology, pathogenicity, immune response, and immune evasion. Written by renowned scientists who have made seminal contributions to the field, this book contains an expansive treatment of the options to track live spirochetes and evaluate gene expression in ticks and mice, provides insights into the workings of the flagellar motor, presents up-to-date research on the modulation of gene expression, and reviews recent studies on the Lyme disease spirochete's networks of regulatory pathways. The volume highlights and describes in detail the tremendous advances in understanding of the Borrelia genus at the molecular and cellular levels as well as the pathogenesis of Lyme disease and relapsing fever. This comprehensive volume is indispensable for anyone involved in Borrelia and Lyme disease research and is highly recommended for microbiologists, immunologists, and physicians with an interest in spirochetes, vector-borne illness, or emerging infectious diseases. The book is a recommended reference volume for all microbiology libraries.

Book Description
The interface between spirochetes and the immune response is of significant importance to their pathogenesis and persistence. Evasion from the immune system leads to infections that present as Leptospirosis, Syphilis, Lyme Disease and Relapsing Fever and may lead to putative persistence and latency. Understanding the mechanisms involved in immune evasion will shed light not only on the hostpathogen factors involved in the process but also on how resistance to infection leads to protection. Broad examples include spirochetal interaction with the immune system, spirochetal molecules involved in immune evasion and in immune activation, innate immune responses in the skin and other compartments, factors involved in spirochetal adhesion to the extracellular matrix, interaction of spirochetes with antigen presenting cells, in vitro, ex vivo or in vivo, spirochetal lipoproteins and immunity. Specific examples include innate immunity to pathogenic spirochetes (T. pallidum, B. burgdorferi and Leptospira spp.), invasion and pathogenesis by L. interrogans, subversion and suppression of B cell responses by B. burgdorferi, role of antibody in clearance versus persistence of relapsing fever Borreliae, evasion of the complement system by B. burgdorferi, immune suppression by Ixodes tick saliva for effective transmission, adhesins and enzymes involved in dissemination of T. pallidum, spirochetal variable surface proteins in immune evasion, intravital imaging of pathogenic spirochetes (Borreliae and Leptospira) in host tissues, spirochete-host surface interactions. Additional specific examples for B. burgdorferi include novel approaches to control infection within the vector and/or in mammal; tick innate immune defenses and interaction of Ixodes scapularis salivary immunomodulatory molecules with human immune cells, tick-innate immune defenses (from the perspective of the tick midgut), mouse models of infection and genetic basis for pathogenicity, diverse roles of outer surface protein C. Additional specific examples for Leptospirosis include animal models of acute, sub-lethal and persistent infection; neutrophils and innate immune response; Toll-like receptor mediated B cell responses; markers of endothelial cell activation for disease severity in human leptospirosis, corticosteroid treatment of advanced human leptospirosis, and urinary biomarkers of chronic Leptospirosis.

Book Description
This book provides a comprehensive discussion on the current information and evidence on the latest developments in the field of drugs resistance. Drug resistance is the reduction in effectiveness of a medication such as an antimicrobial or an antineoplastic in treating a disease or condition. This leads to negative outcomes at great risk of public health; therefore, increasing efforts are dedicated to the development of a new generation of medications that will help deal with this phenomenon. Decades of technological innovations in drug design have demonstrated the potential of resistance. Enormous information on various aspects of antibiotics resistance is available. However, literature on drug resistance specifically related to infectious and non-infectious diseases is rarely presented, particularly those focusing on the mechanisms, biochemistry, kinetics, dynamics, and management of drug resistance. Therefore, there is an immense need for a systematic compilation on the available information about this issue. All the chapters are logically selected and arranged to provide state-of-the-art information about all aspects of drugs resistance. After an introductory chapter, four chapters are dedicated to infectious microbial diseases, whereas two other chapters are complimenting this theme and focusing on drugs resistance in ear, nose and throat, and skin diseases. The recent advances in the understanding of drugs resistance in lung, neurological, kidney, heart, and liver diseases are also covered. Biochemistry of drugs resistance in cancer, HIV, ocular, reproductive, and diabetes diseases is also discussed. Finally, a chapter dedicated to the “management of drug resistance” has been included.

Book Description
Cambridge spy Guy Burgess was a supreme networker, with a contacts book that included everyone from statesmen to socialites, high-ranking government officials to the famous actors and literary figures of the day. He also set a gold standard for conflicts of interest, working variously, and often simultaneously, for the BBC, MI5, MI6, the War Office, the Ministry of Information and the KGB. Despite this, Burgess was never challenged or arrested by Britain's spy-catchers in a decade and a half of espionage; dirty, scruffy, sexually promiscuous, a 'slob', conspicuously drunk and constantly drawing attention to himself, his superiors were convinced he was far too much of a liability to have been recruited by Moscow. Now, with a major new release of hundreds of files into the National Archives, Stewart Purvis and Jeff Hulbert reveal just how this charming establishment insider was able to fool his many friends and acquaintances for so long, ruthlessly exploiting them to penetrate major British institutions without suspicion, all the while working for the KGB. Purvis and Hulbert also detail his final days in Moscow - so often a postscript in his story - as well as the moment the establishment finally turned on him, outmanoeuvring his attempts to return to England after he began to regret his decision to defect.

Book Description
Why Antibiotic Resistance? The use of antibiotics in human and veterinary medicine may have consequences beyond their intended applications. The “One Health” concept recognizes that the health of humans is connected to the health of animals and the environment. Progress in molecular genetics is facilitating the rapid evaluation of the essentiality of these targets on a genomic scale. In 2015, a group of researchers established the International Conference on Antibiotic Resistance (IC2AR).The primary objective of this meeting is to bring together scientists involved in antibiotic resistance prevention and control. The IC2AR conducted its inaugural world congress in January 2015 at Caparica (Portugal). Antimicrobial resistance presents a significant challenge to scientists in the field of infectious diseases. The full knowledge of how antibiotics resistance is evolving and being transmitted between hosts in different ecosystems is taking on great importance. Necessary action includes research to define the scope of the problem including its various sources. This eBook comprises a series of original research and review articles dealing with the epidemiology of resistance in animal and zoonotic pathogens, mobile elements containing resistance genes, the omics of antimicrobial resistance, emerging antimicrobial resistance mechanisms, control of resistant infections, establishing antimicrobial use and resistance surveillance systems, and alternatives strategies to overcome the problem of antimicrobial resistance worldwide. Gilberto Igrejas, José Luis Capelo and Patrícia Poeta Scientific Committee of IC2AR, February 20th, 2017
