Staphylococcus aureus is a common inhabitant of the human body with which we co-exist. However, this species can also cause disease in humans when an appropriate opportunity arises, such as a cut or some other breakdown in our body’s defenses. S. aureus is able to initiate infections due, in part, to the diverse group of toxins that they secrete. The exotoxins produced by S. aureus can cause direct damage, thwart our own body’s defenses, or trigger massive amounts of cytokines that lead to indirect damage within the human body. In this book are 12 research articles that deal with different aspects of staphylococcal exotoxins. Some of the work gives an overview about how the toxins contribute to the disease process. Other articles discuss different aspects of several exotoxins, and two articles are centered on countermeasures against S. aureus infections. Overall, this book will give the reader a good overview of how staphylococcal exotoxins contribute to initiating and sustaining infections in humans.
The ability to form biofilms is a universal attribute of bacteria. Bacteria are able to grow on almost every surface, forming these architecturally complex communities. In biofilms, the cells grow in multicellular aggregates, encased in an extracellular matrix produced by the bacteria themselves. They impact humans in many ways, and can form in natural, medical and industrial settings. For example, the formation of biofilms on medical devices such as catheters or implants often results in difficult-to-treat chronic infections. This book focuses on emerging concepts in bacterial biofilm research, such as the different mechanisms of biofilm formation in Gram negative and Gram positive bacteria, and the burden of biofilm associated infections. It also highlights the various anti-biofilm strategies that can be translated to curb biofilm-associated infections and the escalation of antimicrobial resistance determinants.
Carrying on the high standards of the much praised first edition (Durum and Muegge, Cytokine Knockouts, 1998), Giamila Fantuzzi and a panel of experts have generated completely new chapters to reflect the use of many novel mouse strains and the hundreds of recent studies on cytokine physiology. Comprehensive reviews of the numerous often-surprising results obtained using cytokine knockout mice are provided, along with much important information about cytokine biology and physiology. For those not familiar with cytokine research, the authors present a critical discussion of the advantages and disadvantages of using cytokine knockout mice in various fields of research.
This volume contains a concise review on tranplantation aimed primarily at establishing and developing new knowledge, both in the basic and in the clinical aspects of transplantation. Progress in Transplantation is the summary of a three year project focused mainly on the five fields: rejection, reperfusion injury, traft-versus-hot disease, gene therapy and new approaches to transplantion.
