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.

A set of nine A-4 color plates with 118 photomicrographs illustrating the appearance and diagnostic features of all the common intestinal helminths and protozoan parasites known to infect humans. Produced in a robust plasticized format, the plates can be used as either a guide for laboratory and field workers in endemic countries, or a teaching aid for students and trainees. The aim is to help the microscopist ascertain the presence of parasites in feces, whether they be minute protozoan cysts or large helminth eggs, and to identify them correctly. With this goal in mind, the bench aids include pertinent laboratory instructions as well as high-quality images. The photomicrographs illustrate diagnostic features of each of the parasites as they appear in different preparations and at different magnifications. Each photomicrograph is produced with a measuring bar and accompanied by a short explanatory legend, which draws attention to distinctive features that help confirm diagnosis. Helminth eggs are illustrated in the first 36 photomicrographs, which show the diagnostic stages of the most common helminthes, including nematodes, cestodes, schistosomes, and other trematodes. The remaining photomicrographs offer advice on the more difficult task of detecting and identifying intestinal protozoan trophozoites and cysts. Relevant laboratory techniques are described on the reverse side of the plates. Additional laboratory aids include dichotomous keys for the identification of amoebic trophozoites trophozoites of intestinal flagellates, and cysts of amoebae and flagellates.

Between 300-500 million people are infected with malaria each year, and more than one million, mainly children, die from the disease. These laboratory bench aids are aimed at health workers responsible for diagnosing malaria by microscopic examination of blood films, but will also be useful as teaching aids. The bench aids present photomicrographs, with explanatory text, that show many of the possible variations of malaria parasites.

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.

Developments such as the increasing globalisation of the food industry, new technologies and products, and changes in the susceptibility of populations to disease, have all highlighted the problem of emerging pathogens. Pathogens may be defined as emerging in a number of ways. They can be newly-discovered, linked for the first time to disease in humans or to a particular food. A pathogen may also be defined as emerging when significant new strains emerge from an existing pathogen, or if the incidence of a pathogen increases dramatically. This important book discusses some of the major emerging pathogens and how they can be identified, tracked and controlled so that they do not pose a risk to consumers.After an introductory chapter, Emerging foodborne pathogens is split into two parts. The first part deals with how pathogens evolve, surveillance methods in the USA and Europe, risk assessment techniques and the use of food safety objectives. The second part of the book looks at individual pathogens, their characteristics, methods of detection and methods of control. These include: Arcobacter; Campylobacter; Trematodes and helminths; emerging strains of E. coli; Hepatitis viruses; Prion diseases; Vibrios; Yersinia; Listeria; Helicobacter pylori; Enterobacteriaceae; Campylobacter; Mycobacterium paratuberculosis; and enterocci.Emerging foodborne pathogens is a standard reference for microbiologists and QA staff in the food industry, and food safety scientists working in governments and the research community. - Discusses identification issues - Looks at surveillance methods and the tracking of viruses - Looks at individual pathogens in detail
