In the last quarter century, advances in mass spectrometry (MS) have been at the forefront of efforts to map complex biological systems including the human metabolome, proteome, and microbiome. All of these developments have allowed MS to become a well-established molecular level technology for microorganism characterization. MS has demonstrated its considerable advantage as a rapid, accurate, and cost-effective method for microorganism identification, compared to conventional phenotypic techniques. In the last several years, applications of MS for microorganism characterization in research, clinical microbiology, counter-bioterrorism, food safety, and environmental monitoring have been documented in thousands of publications. Regulatory bodies in Europe, the US, and elsewhere have approved MS-based assays for infectious disease diagnostics. As of mid-2015, more than 3300 commercial MS systems for microorganism identification have been deployed worldwide in hospitals and clinical labs. While previous work has covered broader approaches in using MS to characterize microorganisms at the species level or above, this book focuses on strain-level and subtyping applications. In twelve individual chapters, innovators, leaders and practitioners in the field from around the world have contributed to a comprehensive overview of current and next-generation approaches for MS-based microbial characterization at the subspecies and strain levels. Chapters include up-to-date reference lists as well as web-links to databases, recommended software, and other useful tools. The emergence of new, antibiotic-resistant strains of human or animal pathogens is of extraordinary concern not only to the scientific and medical communities, but to the general public as well. Developments of novel MS-based assays for rapid identification of strains of antibiotic-resistant microorganisms are reviewed in the book as well. Microbiologists, bioanalytical scientists, infectious disease specialists, clinical laboratory and public health practitioners as well as researchers in universities, hospitals, government labs, and the pharmaceutical and biotechnology industries will find this book to be a timely and valuable resource.

Written by specialists in the different fields, this book presents new perspectives and insights into strategies and weapons to fight microbial infections. It also reviews the "state of the art" of alternative treatment approaches and new therapeutic agents to deal with infections caused by multidrug-resistant microorganisms. In an era of accumulated resistance to current antibiotics, it is vital that this is undertaken without further delay. Aspects discussed include the control of RNA synthesis, the use of bacteriocins or enzybiotics (bacteriophages or purified lysins), the specific control of pathogenic clostridia, the design of new drugs affecting DNA synthesis in bacteria, the use of fecal-matter transplant strategies, the specific control of quorum sensing responses in bacteria, the use of new peptides as antibiotics and new ways to control bacteria that cause cancer, such as Helicobacter pylori cancers.

Parasites threaten the health of animals and humans alike. Especially in times of increasing globalization and global warming, parasites can enlarge their "kingdom" by spreading. At the same time many of the existing medical products have become ineffective. As these products have been used for many decades, parasites have developed resistances, so that they have progressed in their fight for survival. Therefore it is obvious that humans must develop new methods to face these dangers. Thus parasitological knowledge increases daily and must be formulated to be accessible for as many parasitologists (veterinarians, physicians, biologists) as possible. Therefore it is necessary that reviews reflecting the present status of the progress in many fields of research be published. Therefore this book, published on the occasion of the 50th anniversary of the German Society of Parasitology, compiles 18 reviews on recent "hot topics," including a new vaccine against malarial parasites; severe diseases with poor chances of treatment (cryptosporidiosis, coccidiosis, theileriosis); vectors (mosquitoes, ticks) and their transmission activities; and fish parasites, including molecular insights into the sex of parasites with a focus on the survival abilities that made them so dangerous. These chapters provide detailed information for researchers, as well as for teachers and students in parasitology.

Flagella-dependent motility is widespread throughout prokaryotes and is advantageous when nutrients are limited as a mechanism to migrate to more favorable environments and to compete with other micro-organisms. Flagella systems can also play an important role in additional processes, such as adhesion to substrates, biofilm formation, and host invasion in pathogenic bacteria. A variety of different classes of pili are found in prokaryotes and these structures also possess a diverse array of functions. Pili are essential for host colonization, virulence, and pathogenesis for many bacteria and, in the case of type IV pili, can also be employed for motility across solid surfaces. This book brings together some of the top scientists in the field and describes the current knowledge and latest research on prokaryotic pili and flagella. The emphasis is on the molecular biology, genetics, structure, assembly, and function of these structures. Topics include: biogenesis, structure, and function of various pili in Gram-negative and Gram-positive organisms * flagellar gene expression, structure, and assembly * the flagella motor * posttranslational modifications of flagella systems * lateral flagella systems * the origin and evolution of flagella * applications of flagella as a surface display and expression system * the flagella and pili of Archaea.

This book is devoted to alkaliphiles, their microbiology, biotechnological applications and adaptive mechanisms. Alkaliphiles are extremophilic organisms that are adapted to thrive in alkaline environments. Over the years, a wide variety of alkaliphiles belonging to domain Bacteria, Archaea and Eukarya have been isolated and studied. These organisms use various adaptive mechanisms to thrive in 'extreme' alkaline environments, and some of these adaptive mechanisms are of immense importance to a range of biotechnological applications. In this book, readers will learn about the adaptive strategies of alkaliphiles in colonizing alkaline habitats, with a main focus on: (1) the production of enzymes that are active and stable in the high pH environment, and (2) the production of acids that decrease the pH of their immediate surrounding environment. Enzymes that are operationally stable at high pH (also known as alkaline active enzymes) are desirable in several applications such as detergent formulating and leather tanning processes, and they are among the major selling enzymes and the most important industrial enzymes. The growing demand in many existing and emerging biotechnological applications led to the discovery, characterization, engineering and evaluation of diverse types of alkaline active enzymes. In addition to the use of these fascinating enzymes in biotechnological applications, readers will discover the mechanisms of action and stability of these enzymes at extreme pH. Studies have shown that some alkaliphiles decrease the severity of the high pH of their media by producing substantial amount of organic acids, which could be of great interest in various applications presented in this book. In addition to enzymes and organic acids, other products of biotechnological importance such as carotenoids, bioactive substances, and chelators have also attracted researchers' attention. Whole-cells of alkaliphiles have been used as food and feed, and are also useful in environmental applications such as in waste treatment and construction.

In the pursuit of technological advancement in the field of biotechnology and pharmaceutical industries to counteract health issues, bacterial infections remain a major cause of morbidity and mortality. The ability of bacterial pathogens to form biofilms further agglomerates the situation by showing resistance to conventional antibiotics. To overcome this serious issue, bioactive metabolites and other natural products were exploited to combat bacterial infections and biofilm-related health consequences. Natural products exhibited promising results in vitro, however; their efficacy in in vivo conditions remain obscured due to their low-solubility, bioavailability, and biocompatibility issues. In this scenario, nanotechnological interventions provide a multifaceted platform for targeted delivery of bioactive compounds by slow and sustained release of drug-like compounds. The unique physico-chemical properties, biocompatibility and eco-friendly nature of bioinspired nanostructures has revolutionized the field of biology to eradicate microbial infections and biofilm-related complications. The green-nanotechnology based metal and metal oxide nanoparticles and polymeric nanoparticles have been regularly employed for antimicrobial and antibiofilm applications without causing damage to host tissues. The implications of these nanoparticles toward achieving sustainability in agriculture by providing systemic resistance against a variety of phytopathogens therefore plays crucial role in growth and crop productivity. Also the advent of smart and hybrid nanomaterials such as metal-based polymer nanocomposites, lipid-based nanomaterials and liposomes have the inherent potential to eradicate bacterial biofilm-related infections in an efficient manner. The recent development of carbon-based nanomaterials such as carbon nanotubes (CNTs) and silica based nanomaterials such as mesoporous silica nanoparticles (MSNs) also exploit a target of dreadful healthcare conditions such as cancer, immunomodulatory diseases, and microbial infections, as well as biofilm-related issues owing to their stability profile, biocompatibility, and unique physio-chemical properties. Recently novel physical approaches such as photothermal therapy (PTT) and antimicrobial photodynamic therapy (aPDT) also revolutionized conventional strategies and are engaged in eradicating microbial biofilm-related infections and related health consequences. These promising advancements in the development of novel strategies to treat microbial infections and biofilm-related multidrug resistance (MDR) phenomenon may provide new avenues and aid to conventional antimicrobial therapeutics.
