Salmonella enterica serovar Enteritidis (S. Enteritidis) is one of the most common serovars associated with poultry and poultry product contamination in the USA. We previously identified fifteen mutant strains of S. Enteritidis phage type 4 (PT4) with significantly reduced invasiveness in human intestinal epithelial cells (Caco-2), chicken macrophages (HD-11) and chicken hepatocellular epithelial cells (LMH). These included S. Enteritidis mutants with transposon insertions in newly identified S. Enteritidis-specific genes (pegD and SEN1393), and genes or genomic islands common to most other Salmonella serovars (SEN0803, SEN0034, KsgA, SEN2278 and SEN3503 ) along with eight genes previously known to contribute to enteric infection (hilA, pipA, fliH, fljB, csgB, spvR, and rfbMN). We hypothesized that S. Enteritidis employs both common Salmonella enterica colonization factors and S. Enteritidis-specific traits to establish infection in chickens. Four S. Enteritidis mutants (SEN0034::Tn5, fliH::Tn5, SEN1393::Tn5 and spvR::Tn5) were indistinguishable from the isogenic wild-type strain when orally inoculated in one-day-old chickens whereas two mutants (CsgB::Tn5 and PegD::Tn5) were defective for intestinal colonization (P

The second edition of Microbiology of Waterborne Diseases describes the diseases associated with water, their causative agents and the ways in which they gain access to water systems. The book is divided into sections covering bacteria, protozoa, and viruses. Other sections detail methods for detecting and identifying waterborne microorganisms, and the ways in which they are removed from water, including chlorine, ozone, and ultraviolet disinfection. The second edition of this handbook has been updated with information on biofilms and antimicrobial resistance. The impact of global warming and climate change phenomena on waterborne illnesses are also discussed. This book serves as an indispensable reference for public health microbiologists, water utility scientists, research water pollution microbiologists environmental health officers, consultants in communicable disease control and microbial water pollution students. Focuses on the microorganisms of most significance to public health, including E. coli, cryptosporidium, and enterovirus Highlights the basic microbiology, clinical features, survival in the environment, and gives a risk assessment for each pathogen Contains new material on antimicrobial resistance and biofilms Covers drinking water and both marine and freshwater recreational bathing waters

Foodborne illnesses continue to be a major public health concern. All members of a particular bacterial genera (e.g., Salmonella, Campylobacter) or species (e.g., Listeria monocytogenes, Cronobacter sakazakii) are often treated by public health and regulatory agencies as being equally pathogenic; however, this is not necessarily true and is an overly conservative approach to ensuring the safety of foods. Even within species, virulence factors vary to the point that some isolates may be highly virulent, whereas others may rarely, if ever, cause disease in humans. Hence, many food safety scientists have concluded that a more appropriate characterization of bacterial isolates for public health purposes could be by virotyping, i.e., typing food-associated bacteria on the basis of their virulence factors. The book is divided into two sections. Section I, “Foodborne Pathogens and Virulence Factors,” hones in on specific virulence factors of foodborne pathogens and the role they play in regulatory requirements, recalls, and foodborne illness. The oft-held paradigm that all pathogenic strains are equally virulent is untrue. Thus, we will examine variability in virulence between strains such as Listeria, Salmonella, Campylobacter, Cronobacter, etc. This section also examines known factors capable of inducing greater virulence in foodborne pathogens. Section II, “Foodborne Pathogens, Host Susceptibility, and Infectious Dose” , covers the ability of a pathogen to invade a human host based on numerous extraneous factors relative to the host and the environment. Some of these factors include host age, immune status, genetic makeup, infectious dose, food composition and probiotics. Readers of this book will come away with a better understanding of foodborne bacterial pathogen virulence factors and pathogenicity, and host factors that predict the severity of disease in humans.

At last, here is a graduate-level textbook that focuses on the very latest information on the molecular and cellular mechanism of several major foodborne bacterial pathogens. For the first time in the field, this book makes the link between foodborne illness and immunology. It also covers virulence genes and their regulation in the host or the food environment, pathogenicity testing models, clinical symptoms and prevention and control strategies. Unlike other textbooks this one also covers the host/parasite interaction to a level where readers have a real appreciation of the disease mechanism. It is imperative that we acquire a better understanding of foodborne pathogens. And this is what this brilliant and timely contribution to the subject offers.

This comprehensive study of poultry meat safety offers readers the most up-to-date information on food safety concerns in poultry meat production. Chapters address recent topics of interest such as organic poultry production, antimicrobial resistant pathogens in poultry, antibiotic usage in poultry production, and pre- and post- harvest approaches to improving poultry meat safety. The last couple of decades have observed a significant increase in poultry meat production in the US. However, poultry meat is a potential source of foodborne pathogens such as Salmonella, Campylobacter spp. and pathogenic Escherichia coli (APEC linked to human infections), leading to economic losses to the poultry industry and impacting public health. Advances in knowledge in microbiology, molecular biology, immunology and “omics” fields have intensified efforts to improve the microbiological safety of poultry by targeting virulence mechanisms of the pathogens, developing vaccines and improving gut health in chickens. Moreover, due to the emergence of multidrug resistance in poultry-borne pathogens, and growth of organic poultry production, there exists significant interest for developing natural strategies for controlling pathogens in chickens. This edited volume provides insight into these strategies and covers other material of interest to food microbiologists, public health personnel, and poultry scientists. Readers of various backgrounds will appreciate its incorporation of recent developments not covered in other publications on the subject.

Over the last few years, bacterial adhesion has become a more and more important and active scientific area, but the field lacks communication and scientific exchange between medical and microbiology researchers who work with the relevant biological systems, and biochemists, structural biologists and physicists, who know and understand the physical methods best suited to investigate the phenomenon at the molecular level. The field consequently would benefit from a cross-disciplinary conference enabling such communication. This book tries to bridge the gap between the disciplines.
