Plant microbe interaction is a complex relationship that can have various beneficial impacts on both the communities. An urgent need of today's world is to get high crop yields in an ecofriendly manner. Utilization of beneficial and multifaceted plant growth promoting (PGP) microorganisms can solve the problem of getting enhanced yields without disturbing the ecosystem thus leading to sustainability. For this to achieve understanding of the intricate details of how the beneficial microbes form associations with the host plant and sustain that for millions of years must be known. A holistic approach is required wherein the diversity of microbes associated with plant and the network of mechanisms by which they benefit the host must be studied and utilized. 'Plant Microbe Symbiosis - Fundamentals and Advances' provides a comprehensive understanding of positive interactions that occur between plant and microorganisms and their utilization in the fields.

This volume reviews the current understanding of the taxonomy, disease syndromes, genetics, biology, and pathogenic factors of Histophilus somni, as well as the host immune response to this pathogen. H. somni is one of the most important bacterial pathogens in cattle and other ruminants, and its virulence factors are highly conserved with Haemophilus influenzae and other members of the Pasteurellaceae. H. somni has been recognized as a major cause of thrombotic meningoencephalitis, respiratory disease syndromes, myocarditis, reproductive disease syndromes, polyarthritis, mastitis, ocular disease, and septicemia. The only known habitats of H. somni are the mucosal surfaces of ruminants, making this bacterium an opportunistic pathogen. Although it is capable of causing inflammation at systemic sites and is toxic to epithelial and phagocytic cells, the bacterium's wide array of virulence factors act primarily as a defense against, or to escape recognition from, host innate and adaptive immunity.

Bacteriocins are a heterogeneous group of peptides or proteins with antimicrobial activity synthesised ribosomally and released extracellularly by bacteria belonging to nearly all taxonomic groups. These are classified according to their genetic, structural and biochemical characteristics. Use of bacteriocinogenic cultures to improve the safety of food products would represent an attractive alternative to the use of chemical preservatives, based on the long history of safe use of naturally occurring bacteriocin producing food-grade bacteria. Chapter One in this book discusses the effects of bacteriocin production in situ by bacteria in food products and evidence for the probiotic properties of bacteriocin producers are collected in order to identify processes in which the application of bacteriocinogenic cultures can be effectively implemented. Chapter Two examines the importance of the use of bacteriocins in food preservation and also their potential use in human health. Chapter Three discusses a broad range of bacteriocin applications focusing not only on food biopreservation but also on biofilm control. Chapter Four reviews the recent applications of bacteriocin-producing PC in meats and meat products throughout the world. Chapter Five evaluates the effect of mild pressure treatments in the survival of Pediococcus acidilactici HA-6111-2 and on its bacteriocin production capacity.

This book introduces Planctomycetes bacteria and deals in detail with their unusual structure, physiology, genomics and evolutionary significance. It is a definitive summary of recent knowledge of this important distinctive group of bacteria, microorganisms which challenge our very concept of the bacterium. Planctomycetes, and their relatives within the PVC superphylum of domain Bacteria, including verrucomicrobia and chlamydia, challenge our classical concept of the bacterium and its modes of life and provide new experimental models for exploring evolutionary cell biology and the full diversity of how living cells can be organized internally. Unique among bacteria, they include species possessing cells with intracellular membrane-bounded compartments and a peptidoglycan-less cell wall, and bacteria such as the anammox organisms performing unique anaerobic ammonium oxidation significant for global nitrogen cycle.

Microbial infection is increasingly seen as a problem as we begin to run out of antibiotics. Understanding how microbes cause disease is essential. In recent years it has begun to emerge that bacteria, fungi, protozoa and viruses can use their cell stress proteins to cause infection. This volume brings together the world's leading experts in the study of the microbial and human cell stress proteins that are involved in enabling microorganisms to infect humans and cause serious disease.

Magnetotactic bacteria (MTB) synthesize intracellular nano-sized minerals of magnetite and/or greigite magnetosomes for magnetic orientation. They play important roles in global iron cycling and sedimentary magnetism, and have a broad range of potential applications in both biotechnological and biomedical fields. However, because the majority of MTB in nature remain unculturable, our understanding of these specific bacteria remains fairly limited. This thesis describes the development of a novel approach for effectively collecting, purifying and characterizing uncultivated magnetotactic bacteria. The diversity, genomic information and rock magnetic properties of various uncultivated MTB are investigated and characterized using a combination of biological and geophysical methods. The results will lead to a better understanding of the biogeography and biomineralization mechanisms of MTB in nature, and improve our knowledge of the contributions of MTB to biogeochemical cycles of elements and sedimentary magnetism.

This detailed book contains chapters using unbiased approaches such as chemical and transposon mutagenesis, as well as a protocol for allelic exchange, to make targeted mutants in Staphylococcus, as generating mutants of this bacteria can be accomplished in many ways, depending on the intended changes. Using these methods, the authors have been successful at making mutants that span individual single-nucleotide changes in the chromosome to whole genome mutant libraries. The latter strategy provides a useful tool for high-throughput screening, while single nucleotide changes are an elegant way of teasing apart the importance of single nucleotides in gene expression or to create specific amino acid substitutions to examine protein function. Written for the Methods in Molecular Biology series, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Practical and authoritative, The Genetic Manipulation of Staphylococci: Methods and Protocols serves as a vital resource and guide to scientists in the Staphylococcus community as they pursue their studies on these bacteria.

Streptococci are Gram-positive bacteria that cause a wide spectrum of diseases, such as pharyngitis, necrotizing fasciitis and streptococcal toxic shock syndrome, as well as rheumatic fever and rheumatic heart disease as sequelae. Antibiotics alone have not been able to control the disease and in spite of many efforts an effective vaccine is not yet available. A prerequisite for novel and successful strategies for combating these bacteria is a complete understanding of the highly complex pathogenic mechanisms involved, which are analyzed in this volume. In ten chapters, prominent authors cover various aspects including streptococcal diseases and global burden, epidemiology, adaptation and transmission, and molecular mechanisms of different diseases, as well as sequelae, vaccine development and clinical management. This book will serve as a valuable reference work for scientists, students, clinicians and public health workers and provide new approaches to meeting the challenge of streptococcal diseases.
