This book was released on 2019-08-27 with total page 169 pages. Available in PDF, EPUB and Kindle. Book excerpt: The human body is constantly faced with microorganisms. Most of these bacteria, fungi, and viruses are harmless, many of them are beneficial, and a small fraction is pathogenic. For humans, infection with pathogenic microorganisms can be very serious or even fatal, ranging from mild transient or chronic infections to death. The first line of defence against pathogens is our innate immune system. Beside chemical and physical defence mechanisms of the innate immune system, phagocytic cells such as macrophages play a crucial role in the fight against pathogenic microorganisms. However, phagocytic cells and pathogens are in a constant evolutionary arms race, inventing new strategies to successfully kill pathogens and learning how to resist phagocytosis and intracellular killing, respectively. If pathogens are not obligatory adapted to the human body or other animals, they also have to face environmental phagocytes in the form of amoebae. Many aspects of phagocytosis and intracellular killing are surprisingly well conserved between amoebae and macrophages. Therefore, pathogens that have evolved with environmental amoebae as their “training grounds” can also be successful during infection of macrophages and other animal phagocytic cells. In this Research Topic, we provide the latest knowledge about the potential of using amoebae as host models to study the interaction with pathogens. The Research Topic covers the interaction of amoebae with bacteria, fungi, and viruses and also illustrates the similarities and differences between amoebae and macrophages. Investigation of evolutionary conserved pathways of amoebae and macrophages furthers our understanding of the biology of host-pathogen interactions and helps to develop new anti-infection therapies.

Download or read book Saprolegniosis written by and published by . This book was released on 2014 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: Saprolegnia is a fresh water fish parasite responsible for significant economic losses in the aquaculture industry worldwide. The disease caused by this organism is termed saprolegniosis, being characterized by a mycosis-like infection of gills and fish skin. Without sustainable treatments available for controlling or preventing saprolegniosis, it has become a significant problem especially for salmon farming, frequently affecting the fish after vaccination. Little is known regarding how the fish immune system responds to infection and such information is vital for developing future treatments and preventive measures to saprolegniosis. To study the immune response of Atlantic salmon to Saprolegnia, a detailed immune profile of experimentally infected presmolts was performed by analyzing the expression levels of several immunity-related genes. Infected fish exhibit a very strong inflammatory response while the majority of genes associate with the adaptive immunity were found to be down regulated. The mechanisms behind this response were then investigated: It was discovered that the cell wall of Saprolegnia can be recognized by fish immune cells, triggering an inflammatory response. A protease secreted by the parasite that has the ability to degrade fish antibodies was identified and, for the first time in an oomycete, the production of prostaglandin E2 was characterized, a molecule that was later shown to potentiate inflammatory responses while suppressing host adaptive immunity genes. Lastly two metabolic pathways of the oomycete were explored as novel targets for control, prostaglandin and sterol metabolism by the use of cyclooxygenase and CYP51 inhibitors, respectively.

Book excerpt: Focusing on pathobiology and protective strategies against protozoan and metazoan parasites of fish, this book reviews the latest research on important parasites: those that cause financial hardships to the aquaculture industry, have been introduced to new geographical regions through transportation of infected fish, are pathogenic to groups of finfish and detrimental to production, are highly adaptable and not host-specific with worldwide distributions, and that may serve as disease models for studies on other pathogens. It also highlights gaps in the knowledge to help direct future research.
Download or read book Fish Diseases and Disorders written by P. T. K. Woo and published by CABI. This book was released on 2006-06-23 with total page 803 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fish is the principal source of protein for people in many parts of the world, particularly in developing countries. While most fish are caught from nature, aquaculture or fish farming is now making a significant contribution to total fish production. More intensive conditions of aquaculture often result in a higher incidence of fish diseases and disorders. As in the first edition, the focus of this second edition is on protozoan and metazoan parasites that cause disease in fish. Significant changes to this second edition include the addition of 3 new chapters and 4 of the original chapters have new authors.

Includes research case studies to exhibit the importance of various integrated approaches to mucosal health Examines the latest scientific methods and technologies to maximize efficiencies for healthy fish production for farming Brings together the latest knowledge and research on mucosal barriers and mechanisms from world-wide experts in mucosal health Utilizes detailed diagrams and figures to enhance comprehension
Download or read book Marine Disease Ecology written by Donald C. Behringer and published by Oxford University Press. This book was released on 2020-01-30 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Whether through loss of habitat or cascading community effects, diseases can shape the very nature of the marine environment. Despite their significant impacts, studies of marine diseases have tended to lag behind their terrestrial equivalents, particularly with regards to their ecological effects. However, in recent decades global research focused on marine disease ecology has expanded at an accelerating rate. This is due in part to increases in disease emergence across many taxa, but can also be attributed to a broader realization that the parasites responsible for disease are themselves important members of marine communities. Understanding their ecological relationships with the environment and their hosts is critical to understanding, conserving, and managing natural and exploited populations, communities, and ecosystems. Courses on marine disease ecology are now starting to emerge and this first textbook in the field will be ideally placed to serve them. Marine Disease Ecology is suitable for graduate students and researchers in the fields of marine disease ecology, aquaculture, fisheries, veterinary science, evolution and conservation. It will also be of relevance and use to a broader interdisciplinary audience of government agencies, NGOs, and marine resource managers.
