The intestinal protozoan Giardia was first described over 300 years ago in 1681 by Leeuwenhoek, from his own stools. In his description of Giardia, he noted the size, movement, and morphology of the organism, and associated its presence with the diarrheic nature of his stools and his dietary habits. This truly remarkable account contains the first description of Giardia in morphologic, pathogenic, and epidemiologic terms. Our knowledge of the organisms in the genus Giardia has advanced tremendously in the past two decades. With the advent of new tech nologies, including techniques in electron microscopy, biochemistry, immunochemistry, tissue culture, and physiology, a tidal wave of information has appeared on the organization and function of this parasitic protozoan and its interaction with its host. The purpose of this book is to celebrate the tricentennial discovery of Giardia by Leeuwenhoek by presenting the above-mentioned advances in our knowledge of Giardia and giardiasis. In the first section of this book, the dominant theme is the biology of the organism and the correlation of structure-function relationships.

Giardia and Giardiasis, Volume 106 in Advances in Parasitology series includes in the first part aspects of molecular and cellular biology of Giardia and the role of particular molecules or molecular groups in essential functions and/or trafficking in the parasite. These approaches are with the aim to explore how this parasite adapts to an ever-changing environment both within and outside of the host animal. Subsequently a comprehensive description of virulence factors secreted by Giardia, are reviewed on their cytotoxic mechanisms and roles in the pathophysiology of giardiasis, and also a description on the potential of these secreted molecules as targets for drugs is included. In the context of the immuno-pathogenesis of giardiasis a review on the data and information on innate and adaptive immunity to Giardia, is included as well as a discussion on how improved knowledge of immunity is advancing our understanding of the pathogenesis and clinical outcomes of giardiasis. The final part of this volume includes a review of the epidemiology of giardiasis in a veterinary context using molecular tools together with a discussion of the current status of the species and assemblages of Giardia, and issues surrounding the assignment of host specificity and the zoonotic potential using current molecular markers. Informs and updates on all the latest developments in the field of parasitology Includes medical studies of parasites of major influence Features reviews of more traditional areas, such as zoology, taxonomy, and life history, which help to shape current thinking and applications

Giardia duodenalis (synonyms G. lamblia or G. intestinalis), the only species belonging to the genus Giardia found in humans, is a pathogenic protozoan with a worldwide distribution having a more relevant prevalence in warm climate and in children. G. duodinalis is a water-borne flagellated parasite that causes giardiasis in humans. In addition, giardiasis affects domestic and wild mammals “e.g., cats, dogs, cattle, deer, and beavers” (Thompson, 2000). Host-to-host transference of Giardia cysts takes place via the fecal-oral route. This allows the protozoan to infect the next generation of hosts through a diverse range of mechanisms: person to person, animal to human or by contact with contaminated water and food. Outbreaks commonly occur in areas with inadequate water treatment, especially developing countries, where infection rates can be higher than 50% of the total population. It is well documented that in developing countries, infections are associated with poor sanitary conditions, poor water quality and overcrowding. Giardia is one of the leading protozoan causes of gastrointestinal illness worldwide and has joined the ranks of the WHO Neglected Diseases Initiative. Giardiasis constitutes an important public health problem in Egyptian children. Contamination of the Nile River with fecal materials including viruses and pathogenic protozoa still represents an environmental health hazard in Egypt, especially in rural areas. The clinical features of giardiasis range from acute or chronic diarrhea, abdominal pain, nausea, flatulence, vomiting, weight loss, to absence of symptoms and signs. In the diagnosis of Giardia, stool examination is the traditional, safest and easiest method. Microscopy of Giardia cysts and trophozoites is more straightforward, and there is little risk of confusion with other parasites. Moreover, only “ghost” cysts with an empty appearance are sometimes not recognized as Giardia parasites. However, the sensitivity of microscopy is quite low due to the intermittent excretion of Giardia cysts, the microscopical examination of a single stool specimen has a low sensitivity and may therefore miss up to 50% of Giardia infections. And thus, it is recommended that at least three samples be examined in order to rule out giardiasis which is time consuming and delay the diagnosis.

Also, its sensitivity depends on the burden of infection, the freshness of the specimen and the experience level of the microscopist. Stains are used to improve detection of specific organisms.

This book focuses on the developments of giardiasis during the last decade, taking into account factors which have contributed to this, including the introduction of anti-Giardia agents and the development of culture methods for Giardia. Now recognized as one of the 10 major parasites of humans, Giardia is found world-wide and although transmitted fecal-orally, the precise means of transmission varies. The diverse views held in different parts of the world regarding the treatment of Giardia-infected individuals are reconciled in this book to provide an up-to-date, comprehensive and single-source reference, compiled by experts foremost in their field. The ultimate aim of the book is to considerably help promote research in this area, and thereby decrease the extensive impact of giardiasis. The scope of potential readers is broad: including the researcher, teacher, clinician and public health administrator alike.
