This manual has been developed to provide those who are involved in the diagnosis of parasitic diseases with a resource that encompasses the basic technology required for detection of parasites and identification of their diagnostic stages in feces, blood, other body fluids, and tissues. In addition to the technical procedures described, a summary of the morphologic charateristics that are used in the identification of protozoa and helminths is provided as well as line drawings, original color representations of the stages of the human malarial parasites, and photomicrographs of the diagnostic stages of many parasites.
Diagnostic Medical Parasitology covers all aspects of human medical parasitology and provides detailed, comprehensive, relevant diagnostic methods in one volume. The new edition incorporates newly recognized parasites, discusses new and improved diagnostic methods, and covers relevant regulatory requirements and has expanded sections detailing artifact material and histological diagnosis, supplemented with color images throughout the text.

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.
In the 21st century the field of diagnostic medical parasitology continues to see dramatic changes, including newly recognized pathogens and the changing endemicity and classification of familiar organisms; neglected tropical diseases and the impact of global climate change; and new methodologies and risk management issues. This classic clinical laboratory parasitology reference, now in its third edition, has been extensively revised and updated in a new full-color format. Still organized to provide maximum help to the user, particularly from the bench perspective, every section has been expanded with new images and discussion. Specimen collection, preservation, and testing options are thoroughly discussed, from the routine ova and parasite examination to blood films, fecal immunoassays, and the newer molecular test panels. Specific test procedures, laboratory methods and reagents, and algorithms are provided. The ever-helpful "FAQ" section of commonly asked questions now offers expanded information on stool specimen fixatives and testing, thorough coverage of new techniques, and advice on reporting and commenting on results. The heart of the Guide, covering identification of individual pathogens, has been expanded with more discussion and comparison of organisms and dozens of new color images. An entirely new section has been added that uses extensive figures and new tables to illustrate common problems with differentiating organisms from one another and from possible microscopic artifacts. The final section has been reorganized to include identification keys and dozens of tables summarizing organism characteristics to assist the bench microbiologist with routine diagnostic testing methods.
Over 1,200 total pages .... Parasitic infection can greatly interfere with a soldier's ability to complete his mission. The presence of parasites in a soldier's system can not only interfere with his ability to function, but also can make him susceptible to certain diseases. Since soldiers may serve in most areas of the world, you must be able to identify parasites that are found in the various parts of the globe. In your job as a medical laboratory specialist, you will perform a variety of test procedures on samples taken from humans. Some of these samples will include feces and tissue scrapings used in the diagnosis and treatment of parasitic infection. Therefore, you must be knowledgeable in several areas of parasitology. The knowledge you will need is reflected in the two subcourses you are about to study. Subcourses Parasitology I and Parasitology II address areas of particular importance in parasitology. The whole purpose of clinical laboratory procedures is to provide the clinician doing diagnostic work with specific information needed to round out his picture of the disorders he has observed in the patient. Clinical bacteriology can contribute its part by supplying data about the microscopic life involved and the susceptibility of such life to particular drugs. To identify bacterial growth, you must take certain steps that will enable you, through a process of elimination, to choose the microscopic form that fits the findings you have obtained. Steps that are often essential include: 1. Observing the type of growth when first isolated on culture media. 2 Making a microscopic examination on stained material from an isolated culture of that colony. 3. Performing various tests to obtain a list of the characteristics of the organism. 4. Making a complete identification of the organism. This subcourse was developed to prepare and sustain your mathematical skills as a Medical Laboratory Specialist. The emphasis is upon computations related to solutions and their concentrations. If you feel that you need a more basic review of mathematics before taking this subcourse, you should request Subcourse Basic Mathematics, which covers addition, subtraction, multiplication, and division of whole numbers; decimals, and fractions; and conversions to and from the metric system. In the process of achieving and maintaining proficiency in your military occupational specialty (MOS), you will be learning concepts and performing tasks that are based on important chemical principles. As you become more proficient with these principles, you may reach the point where you will not need to give them much conscious thought. Meanwhile, however, you should study this subcourse to gain a working knowledge of the fundamental principles of chemistry. Subcourse Clinical Chemistry I, provides you with a background in the laboratory basics of clinical chemistry. Laboratory safety; collection, preservation, and shipment of specimens; measurement of weights and volumes; introduction to quality control; and introduction to organic chemistry are presented in this subcourse.
