Parasitism is a tight association between species in which one organism, the parasite, lives on or inside the host, causing it harm, and is structurally adapted to this way of life. Until the twenty-first century, parasitism was studied by parasitologists, rather than ecologists or evolutionary biologists. Today, parasitism is a major element of evolutionary ecology, as nearly all free-living animals are hosts to at least one parasite species. Since it is in the parasite's evolutionary interest for its host to flourish, long-term coevolution can lead to a stable relationship bordering on mutualism. According to Lynn Margulis, when resources are scarce, natural selection, moves relationships from parasitism to mutualism, as it was brilliantly illustrated in Margulis' endosymbiosis theory, where eukaryotic mitochondria and chloroplasts descended from formerly free-living prokaryotes. Boundary between mutualism, symbiosis, and pathological parasitism is a thin red line that frequently overlapping without a theory enough clear to explain this thigh relationship between the parasite and its host.
Campylobacter is the major cause of food-borne bacterial diarrheal illnesses worldwide. Many wild and domestic animals carry the organism in their intestines. Intestinal colonization results in the transmission of Campylobacteriosis to healthy animals, and epidemiological studies imply that contaminated animal products contribute to Campylobacteriosis. Interventions in animal production offer the best chance of minimizing illness risk. In addition, implementing enhanced hygiene standards and decontamination can reduce the prevalence of Campylobacter contamination in animal meat. This book investigates Campylobacter’s significance as a food-borne pathogen and summarizes recent breakthroughs in isolation, identification, the involvement of immune responses and microbiota, as well as novel control strategies.
Gut health and specifically the gut microbiome-host interaction is currently a major research topic across the life sciences. In the case of animal sciences research into animal production and health, the gut has been a continuous area of interest. Production parameters such as growth and feed efficiency are entirely dependent on optimum gut health. In addition, the gut is a major immune organ and one of the first lines of defense in animal disease. Recent changes in animal production management and feed regulations, both regulatory and consumer driven, have placed added emphasis on finding ways to optimize gut health in novel and effective ways. In this volume we bring together original res...
In the intricate world of microbiology, few names evoke as much intrigue and concern as Enterococcus. Once considered a benign inhabitant of the human gut, this resilient bacterium has emerged as a formidable pathogen, capable of outwitting some of our most advanced medical defenses. Enterococcus - Unveiling the Emergence of a Potent Pathogen is a compelling exploration into the rise of this tenacious microorganism and the chapters of this book dig into the complex biology, adaptive mechanisms, and the significant clinical implications of Enterococcus. Through meticulous research and captivating narratives, this book sheds light on how Enterococcus has evolved, its role in hospital-acquired ...
Tomorrow in the Battle Think on Me is a gripping and moving meditation on the hold that the dead have over the living, by Javier Marías, whose highly-anticipated new novel The Infatuations is published in 2013. Víctor, a ghostwriter, is just about to have an affair with Marta, a married woman, when - in the bedroom, half-undressed - she drops dead in his arms. He panics and slips away. But Marta's family are all too aware that she was not alone when she died, and Deán, the widowed husband, is determined to find out who was sharing her bed that night. Víctor, accustomed to a life of pretending, finds that he cannot live in the shadows forever.
The gut-brain axis has gained considerable attention from different branches of the scientific community in recent years. In this book, scientists from different disciplines present current scientific knowledge on the topic. The interaction between the prokaryote and eukaryote cells stimulates the evolutionary processes, and results in various systemic illnesses such as neuropsychiatric disorders and may help the continuity of health. Nature has provided us with healthy food that builds our pharmacy. This natural pharmacy store may help the body's healing processes through its effects on gut microbiota and the immune system. This book aims to provide the reader with detailed analyses of the current scientific knowledge on the gut-brain axis and its relation with health and disease. We hope that the reader benefits from the presented material.
