The bacterium Salmonella enterica is a serious bacterial pathogen and causative agent of salmonellosis infections on a worldwide scale. Many clinical isolates of S. entericaS. enterica. Following this, the strengths and limitations of the available molecular tools for effective epidemiological assessment of foodborne salmonellae are collected and critically discussed. Such integration would allow accurate identification of both infection source and transmission route that would lead to implementation of effective control measures. Additionally, the role of Salmonella enterica as a possible therapeutic alternative in the fight against cancer. Although Salmonella enterica tumor selectivity remains unclear, pre-clinical and clinical trials have shown its localization in solid, semi-solid and metastatic tumours. The final chapter reviews some mechanisms and recent trends in the spread of multidrug resistant Salmonella enterica. serovar in Nigeria. Antibiotic use both in animal and human medicine and environmental factors, all have a role in the emergence, persistence and spread of resistance.

Antiseptics and disinfectants are extensively used at home, in occupied buildings, recreational areas, industries (the water industry, food processing industry and pharmaceutical industry, among others), hospitals and other healthcare settings for a variety of topical and hard-surface applications. They play a critical role in controlling the spread of environmentally transmitted pathogens in healthcare and food-processing environments, as well as at home. A wide variety of active chemical agents are found in these products, many of which have been used for hundreds of years for antisepsis, disinfection, and preservation. Although its main purpose is to control human exposure to microorganisms through preventive action, its use should also be carefully controlled in order to prevent healthcare problems that may consequently emerge due to their toxicity. The problems regarding the use of disinfectants are not new, although unquestionably tangible and pertinent, due to its broad application in the referred economical activities, as well as due to the development and emerging of new compounds with this activity. This book aims to address the various scenarios regarding the use of disinfectants. Accordingly, through its eleven chapters it is possible to become aware of the wide range of disinfectant applications, as well as the concerning advantages and limitations of its use. This book is divided into two main sections. The first section, after an overview regarding the use of disinfectants in society, addresses questions related to its toxicology and health repercussions along with microbiological mechanisms. In the second section, a far-reaching exploration of the application of disinfectants in a set of specifically selected economic activities, alongside issues concerning their environmental impact and regulatory matters is addressed. This section also includes two case studies on novel disinfection methods.

This current book provides an overview of current research on bacteriophages. Chapter One discusses bacteriophages of pathogenic vibrios, identification and differentiation. Chapter Two reviews recent literature about the application of phages for the biocontrol of microorganisms in meat and meat products, with a particular emphasis on chicken, beef and pork in order to shed light on the efficacy of such strategy for the prevention and/or eradication of spoilage and pathogenic microorganisms in foods and food processing environments. Chapter Three studies the synthesis of the divalent cation requirements for efficient adsorption of bacteriophage onto bacterial cells. Chapter Four focuses on the isolation and evaluation of the lytic spectrum of bacteriophages active against food-borne bacteria. Chapter Five presents data about the history and present-day of using bacteriophage preparations in treatment and prevention of various infectious diseases, in particular of suppurative-inflammatory diseases of the respiratory organs. Chapter Six reviews phagebiotics in treatment and prophylaxis of healthcare-associated infections.

Microbial biofilms are populations of microorganisms that are found on solid-liquid interface and are typically surrounded by a matrix of extracellular polymeric substances (EPS). The aggregates of cells not firmly attached to a surface are sometimes termed flocs and have the same characteristics as biofilms. Bacteria in the biofilms produce an extracellular matrix and this contributes to ~90% of the biofilm biomass. They are found in all environments such as marine, freshwater, industrial surfaces, domestic appliances exposed to tap water and wastewater, dental surfaces, medical implants etc. This book discusses the characterization, applications and recent advances in the study of biofilms.

The book will provide an overview of the advancement of fundamental knowledge and applications of antimicrobial peptides in biomedical, agricultural, veterinary, food, and cosmetic products. Antimicrobial peptides stand as potentially great alternatives to current antibiotics, and most research in this newly-created area has been published in journals and other periodicals. It is the editors' opinion that it is timely to sum up the most important achievements in the field and provide the scientific community in a reference book. The goals of this project include illustrating the achievements made so far, debating the state of the art, and drawing new perspectives.

A comprehensive manual of phytobacteriology, this work is heavily illustrated with over 200 colour photographs and line illustrations. It begins by outlining the history and science of bacteriology and gives an overview of the diversity and versatility of complex bacteria. It then explains the characterization, identification and naming of complex bacteria, and explores how bacteria can cause disease and how plants react to such disease. The book also discusses the economic importance of bacterial diseases as well as strategies for their control and the reduction of crop losses. It concludes with 50 examples of plant pathogenic bacteria and the diseases that they cause.

Bacteria belonging to the genus Klebsiella have a dual role in human pathophysiology. Some of the strains are potent opportunistic pathogens capable of causing severe illnesses, whereas a majority of the klebsiellas belong to our normal flora, particularly in our alimentary tract. In this book, the authors present current research in the study of the epidemiology, pathogenesis and clinical outcomes of klebsiella infections. Topics discussed include interactions of klebsiella sp. with other intestinal flora; C-9154 derivatives with potent in vitro biological activity against klebsiella pneumoniae; treatment strategies for infections caused by carbapenem resistance and pandrug resistant klebsiella isolates; clinical characteristics of klebsiella pneumoniae pneumonia in alcoholic patients and virulence factors of the isolates; klebsiella pneumoniae endogenous endophthalmitis; klebsiella pneumoniae liver abscess; virulence mechanisms of the klebsiella; and multi-drug resistant klebsiella pneumoniae and K. oxytoca strains in Russian hospitals.

Bacteriophages (phages) are the viruses of bacteria and biofilms that represent a frequent niche for bacteria, where they are embedded in extensive extracellular polymeric substances (EPS) and can be structured into complex microcolonies. As a consequence of the resulting spatial structure and heterogeneity, phage-bacterial interactions within biofilms can be more complicated than those between phages and planktonic bacteria. This book presents and discusses research which provides a better understanding of the biology of phages interacting with biofilms.

This book presents topical research in the study of E. coli infections, including urinary tract infections caused by E. coli; aptamer-based detection and therapeutics to prevent and treat E. coli infections; Lactoferrin as a novel natural host defence protein; enterotoxigenic escherichia coli colonisation factors and the prevention of E. coli using organic acids.

Agrobacterium is a plant pathogen which causes the "crown-gall" disease, a neoplastic growth that results from the transfer of a well-defined DNA segment ("transferred DNA," or "T-DNA") from the bacterial Ti (tumor-inducing) plasmid to the host cell, its integration into the host genome, and the expression of oncogenes contained on the T-DNA. The molecular machinery, needed for T-DNA generation and transport into the host cell and encoded by a series of chromosomal (chv) and Ti-plasmid virulence (vir) genes, has been the subject of numerous studies over the past several decades. Today, Agrobacterium is the tool of choice for plant genetic engineering with an ever expanding host range that includes many commercially important crops, flowers, and tree species. Furthermore, its recent application for the genetic transformation of non-plant species, from yeast to cultivated mushrooms and even to human cells, promises this bacterium a unique place in the future of biotechnological applications.

The book is a comprehensive volume describing Agrobacterium's biology, interactions with host species, and uses for genetic engineering.
