À propos de cet e-book

Toxoplasmosis is caused by a one-celled protozoan parasite known as Toxoplasma gondii. In the United States, it is estimated that approximately 30% of cats, the primary carriers, have been infected by T. gondii. Most humans contract toxoplasmosis by eating cyst-contaminated raw or undercooked meat, vegetables, or milk products or when they come into contact with the T. gondii eggs from cat feaces while cleaning a cat's litterbox, gardening, or playing in a sandbox. Approx 1 in 4 (more than 60 million) people in the USA are infected with the parasite, and in the UK between 0.5 and 1% of individuals become infected each year. By the age of 50, 40% of people test positive for the parasite. The predilection of this parasite is for the central nervous system (CNS) causing behavioral and personality alterations as well as fatal necrotizing encephalitis, and is especially dangerous for HIV infected patients.

Though there have been tremendous strides in our understanding of the biology of Toxoplasma gondii in the last decade, there has been no systemic review of all of the information that has accumulated. Toxoplasma gondii provides the first comprehensive summary of literature on this organism by leading experts in the field who were responsible for organising the 7th International Congress on Toxoplasmosis in May 2003. It offeres systematic reviews of the biology of this pathogen as well as descriptions of the methods and resources used. Within the next year the T. gondii genome will be completed making this an indispensable research resource for biologists, physicians, parasitologists, and for all those contemplating experiments using T. gondii.

* Serves as a model for understanding invasion of host cells by parasites, immune response, motility, differentiation, phylogenetics, evolution and organelle acquisition
* Discusses the protocols related to genetic manipulation, cell biology and animal models while also providing reference material on available resources for working with this organism

À propos de l'auteur

Louis M. Weiss M.D., M.P.H is Professor of Medicine (Division of Infectious Diseases) and Professor of Pathology (Division of Parasitology and Tropical Medicine) of the Albert Einstein College of Medicine, Bronx, New York. Dr. Weiss received his M.D. and M.P.H degrees from the Johns Hopkins University in 1982. He then completed a residency in Internal Medicine at the University of Chicago and a fellowship in Infectious Diseases at the Albert Einstein College of Medicine. Following this fellowship, he joined the faculty at Einstein where he is currently a Professor of Pathology and Medicine. His laboratory group has an active research program on parasitic diseases with a research focus on Toxoplasma gondii, the Microsporidia and Trypanosoma cruzi. Dr. Weiss is the author of over 200 publications and the editor of 3 books on parasitology. He is a fellow of the American College of Physicians, Infectious Disease Society of America and the American Academy of Microbiology. Dr. Weiss is the Co-Director of the Einstein Global Health Center.

Dr. Kami Kim is a physician-scientist who joined the USF faculty in 2017 as a Professor of Internal Medicine (Infectious Diseases and International Medicine) and Professor of Global Health. Her laboratory focuses upon understanding the pathogenesis of toxoplasmosis and malaria, parasitic diseases of global significance. The Toxoplasma projects use a multidisciplinary systems biology approach to understand how the parasite senses and responds to changes in its host. Using a combination of epigenomics, genetics and proteomics, her group is studying how the parasite transitions from the pathogenic tachyzoite form to the persistent bradyzoite form. She is investigating the epigenetic and genetic factors that govern the host response to parasites. Dr. Kim is a fellow of the American Academy of Microbiology and the Infectious Disease Society of America as well as an elected member of the Association for American Physicians and the American Society for Clinical Investigation.
