Novel Approaches to the Control of Helminth Parasites of Livestock


Book Description

The International Conference of Novel Approaches to The Control of Helminth Parasites of Livestock (NA) meetings has aimed to stimulate links between scientists and extension specialists and from developed, emerging and developing countries. The objective is to unite researchers that are starting to realize that helminth control could not be sustainable by the sole use of synthetic anthelmintics. Now, and although helminth infection of livestock remains a major worldwide issue for animal health, a number of alternative strategies have been proposed to alleviate their economic impact and to improve animal welfare. In 2016, the NA Conference was held in Belem, PA, Brazil with the support of the Brazilian College of Veterinary Parasitology, CBPV. The current monograph includes 15 manuscripts of the discussion papers submitted at the 8th NA Conference. These include, target treatment and Famacha method, interaction of feeding behavior and parasite infections, mapping resistant population by molecular and fecal techniques, ethnoveterinary and the use of plants, fungi and bacteria to control helminths, vaccines, new compounds, and the use of artificial intelligence to estimate parasite incidence.







Modelling Parasite Transmission and Control


Book Description

It is clear that many fascinating problems still remain to be addressed in parasite transmission modelling, from better understanding of transmission processes and natural history of infection to investigating the impact of ecological and spatial scales, climate change, host immunity and social behaviour, parasite-host evolutionary dynamics and parasite community ecology on parasite transmission. This book captures some of the advances made in recent years and provides indications of ways forward for addressing these questions by shedding light on developments in conceptual frameworks and modelling tools as well as the emergence of new data forms for aiding model construction, testing and analysis. Another important advance has been the parallel development of robust computationally-intensive statistical methods to allow model testing and parameterization by aiding the fitting of models to complex data. This is an exciting area of work, which we believe will broaden the scope of mathematical modelling in investigating parasite transmission processes. In particular, we expect this advance will now allow modellers to begin the successful development and analysis of mechanistically-rich models of parasite transmission that will facilitate better integration of the variety of mechanisms increasingly recognized as important in simultaneously affecting transmission, including abiotic processes, trophic and evolutionary interactions, movement in space, and behaviour and even physiology of the individual. We foresee a continuing bright future for using mathematical modelling to clarify parasite transmission dynamics and address problems related to effective parasite control. Ultimately, through this improved application of models to research and management, we expect that parasite control would be an achievable goal bringing benefits to a vast number of our fellow human beings.




Investing to Overcome the Global Impact of Neglected Tropical Diseases


Book Description

"The presence, or absence, of neglected tropical diseases (NTDs) can be seen as a proxy for poverty and for the success of interventions aimed at reducing poverty. Today, coverage of the public-health interventions recommended by the World Health Organization (WHO) against NTDs may be interpreted as a proxy for universal health coverage and shared prosperity - in short, a proxy for coverage against neglect. As the world's focus shifts from development to sustainable development, from poverty eradication to shared prosperity, and from disease-specific goals to universal health coverage, control of NTDs will assume an important role towards the target of achieving universal health coverage, including individual financial risk protection. Success in overcoming NTDs is a "litmus test" for universal health coverage against NTDs in endemic countries. The first WHO report on NTDs (2010) set the scene by presenting the evidence for how these interventions had produced results. The second report (2013) assessed the progress made in deploying them and detailed the obstacles to their implementation. This third report analyses for the first time the investments needed to achieve the scale up of implementation required to achieve the targets of the WHO Roadmap on NTDs and universal coverage against NTDs. INVESTING TO OVERCOME THE GLOBAL IMPACT OF NEGLECTED TROPICAL DISEASES presents an investment strategy for NTDs and analyses the specific investment case for prevention, control, elimination and eradication of 12 of the 17 NTDs. Such an analysis is justified following the adoption by the Sixty-sixth World Health Assembly in 2013 of resolution WHA6612 on neglected tropical diseases, which called for sufficient and predictable funding to achieve the Roadmap's targets and sustain control efforts. The report cautions, however, that it is wise investment and not investment alone that will yield success. The report registers progress and challenges and signals those that lie ahead. Climate change is expected to increase the spread of several vector-borne NTDs, notably dengue, transmission of which is directly influenced by temperature, rainfall, relative humidity and climate variability primarily through their effects on the vector. Investments in vector-borne diseases will avoid the potentially catastrophic expenditures associated with their control. The presence of NTDs will thereby signal an early warning system for climate-sensitive diseases. The ultimate goal is to deliver enhanced and equitable interventions to the most marginalized populations in the context of a changing public-health and investment landscape to ensure that all peoples affected by NTDs have an opportunity to lead healthier and wealthier lives."--Publisher's description.




Bench aids for the diagnosis of intestinal parasites


Book Description

This second edition of Bench aids for the diagnosis of intestinal parasites is intended both as a practical tool for the diagnosis of intestinal parasitic infections for laboratory and field workers and as a teaching aid for students and trainees. The plates are arranged on two sides: the recto with microphotographs for the identification of eggs larvae trophozoites cysts and oocysts occurring in faeces and the verso dedicated to the different copromicroscopical methods (procedures) and main staining techniques used in parasitology. Special attention has been devoted to all graphical and pictorial contents. The decision to include the outline of an Ascaris lumbricoides egg in its relative size next to each parasitic structure fulfils the intention of visualizing the actual dimensions that the eye needs to be looking for when examining the specimens with a microscope. For each image the size of the parasite and a short description are provided to assist in the microscopical identification. Two summary plates one for helminths and the other for protozoa are also included to provide a visual overview of the different presentations of parasitic elements. The bench aids have been produced in a weatherproof plastic-sealed format that is robust and easy to use at the bench. They are recommended for use by all health workers engaged in the routine diagnosis of intestinal parasitic infections.




Helminth Control in School-Age Children


Book Description

More than 2000 million people worldwide are affected by schistosomiasis and soil-transmitted helminth (STH) infections and 155 000 deaths are reported each year. These infections are diseases associated with poverty, and in school-age populations in developing countries, intestinal helminth infections rank first among the causes of all communicable and noncommunicable diseases. This book describes a cost-effective approach to the control of these infections, based on the use of periodic parasitological surveys of school population samples. It is intended as a guide for health education managers responsible for implementing community-based programmes.




Disease Control Priorities, Third Edition (Volume 6)


Book Description

Infectious diseases are the leading cause of death globally, particularly among children and young adults. The spread of new pathogens and the threat of antimicrobial resistance pose particular challenges in combating these diseases. Major Infectious Diseases identifies feasible, cost-effective packages of interventions and strategies across delivery platforms to prevent and treat HIV/AIDS, other sexually transmitted infections, tuberculosis, malaria, adult febrile illness, viral hepatitis, and neglected tropical diseases. The volume emphasizes the need to effectively address emerging antimicrobial resistance, strengthen health systems, and increase access to care. The attainable goals are to reduce incidence, develop innovative approaches, and optimize existing tools in resource-constrained settings.
