Book Description
Staphylococcus spp. and Streptococcus spp. have not only got pathogenic isolates, but also non-pathogenic isolates. Staphylococcus spp. and Streptococcus spp. that are Gram positive cocci are the main pathogens in several infections. Virulence factors such as usual and unusual surface proteins encoded by resistance genes are the main causes of pathogenesis. Multidrug-resistant pathogens that are the main causes of morbidity and mortality worldwide have the ability to synthesize a number of destructive enzymes encoded by resistance genes such as ?-lactamases. Resistant pathogens such as methicillin-resistant Staphylococcus aureus (MRSA), Streptococcus pneumoniae, Group A, and Group B Streptococcus have emerged throughout the world. To eliminate these resistant pathogens that cause untreatable, acute, and chronic infections, different new antimicrobials must be developed and used. The goal of this book is to provide the latest information about the above topics.

Book Description
This plan addresses the need to improve our ability to identify infectious disease threats and respond to them effectively by improving the public health infrastructure at the local, state and federal levels. The goals of the plan are surveillance (detect, promptly investigate, and monitor emerging pathogens, the diseases they cause, and the factors influencing their emergence); applied research (integrate laboratory science and epidemiology to optimize public health practice); prevention and control (enhance communication of public health information about emerging diseases and ensure prompt implementation of prevention strategies); and infrastructure (strengthen local, state, and federal public health infrastructures to support surveillance and implement prevention and control programs).

Book Description
Members of the genus Staphylococcus and Streptococcus are the causative agnets of many human and animal diseases. Over the past decade the complete sequencing of many staphylococcal and streptococcal genomes has promoted a significant advance in our knowledge of these important pathogens. The pathogenicity of these bacteria is due to the expression of a large variety of virulence factors. Such determinants, which are cell wall-associated and secreted proteins, include adhesins that confer to the pathogen the ability to attach to extracellular matrix/plasma and host cell surfaces, proteins that contribute to host cell invasion and intracellular survival and soluble factors that decrease phagocytosis and modulate the immune response. Furthermore, these Gram-positive cocci in many natural environments (heart valve, lung, oral cavity, throat) and infections on implanted devices live in matrix-encased groups known as biofilms. Biofilms are specialized bacterial communities with high order organization analogous to that of a tissue in multicellular organism that adhere to abiotic or biological substrata and produce an exopolymeric matrix composed of polysaccarides, proteins, DNA or combination thereof. Bacteria within a biofilm persist in adverse conditions, show resistance to killing by antibiotics and to host immune defences and are difficult to eradicate and treat clinically. Therefore, understanding the mechanisms of biofilm development will allow us to effectively combat staphylococcal/streptococcal biofilm-based infections. This Research Topic will focus on the molecular components involved in biofilm formation by staphylococci and streptococci, the role they play in the development, maturation and dispersal of biofilm and on the regulatory aspects of such complex processes. The implication for the pathogenesis of infective diseases and potential therapeutic strategies against biofilm-based infections will be also discussed. The articles will highlight both the recent advances and future challenges inherent in this rapidly evolving area.

Book Description
This comprehensive volume provides a platform from which both major and minor infectious diseases related issues are addressed in-depth among this highly susceptible population. The book begins with an overview of infections in various modalities. This is followed by chapters on clinical disorders, etiologic agents, therapeutics, and infection prevention. Chapters include easy-to-follow figures and tables, radiologic images, and pictorial demonstrations of various disease states to familiarize and reacquaint the transplant clinicians and surgeons in practice and training, and those belonging to subspecialties providing supportive care for these patients. Discussions to enumerate the noninfectious causes that mimic infectious diseases; clinical relevance and effective utility of existing and emerging diagnostic tools are presented throughout the book. Authored by leaders in their fields, this book is the go-to reference for management of patients undergoing hematopoietic and solid organ transplantation.

Book Description
Throughout the biological world, bacteria thrive predominantly in surface-attached, matrix-enclosed, multicellular communities or biofilms, as opposed to isolated planktonic cells. This choice of lifestyle is not trivial, as it involves major shifts in the use of genetic information and cellular energy, and has profound consequences for bacterial physiology and survival. Growth within a biofilm can thwart immune function and antibiotic therapy and thereby complicate the treatment of infectious diseases, especially chronic and foreign device-associated infections. Modern studies of many important biofilms have advanced well beyond the descriptive stage, and have begun to provide molecular details of the structural, biochemical, and genetic processes that drive biofilm formation and its dispersion. There is much diversity in the details of biofilm development among various species, but there are also commonalities. In most species, environmental and nutritional conditions greatly influence biofilm development. Similar kinds of adhesive molecules often promote biofilm formation in diverse species. Signaling and regulatory processes that drive biofilm development are often conserved, especially among related bacteria. Knowledge of such processes holds great promise for efforts to control biofilm growth and combat biofilm-associated infections. This volume focuses on the biology of biofilms that affect human disease, although it is by no means comprehensive. It opens with chapters that provide the reader with current perspectives on biofilm development, physiology, environmental, and regulatory effects, the role of quorum sensing, and resistance/phenotypic persistence to antimicrobial agents during biofilm growth.

Book Description
Staphylococcus was first recognized as a human pathogen in 1880 and was named for its grape cluster-like appearance. In 1884, Staphylococcus aureus was identified and named for its vibrant golden color, which was later found to be the result of golden toxin production. Here, experts examine in-depth patterns of S. aureus colonization and exposures in humans, mammals, and birds that have led to the development of various clinical diseases. The mode of transmission of S. aureus and different methods for its detection in different samples are defined. Conventional antibiotic options to treat this aggressive, multifaceted, and readily adaptable pathogen are becoming limited. Alternative, novel chemotherapeutics to target S. aureus are discussed in the pages within, including herbal medicines, bee products, and modes of delivery.
