American Trypanosomiasis

American trypanosomiasis, or Chagas disease, is caused by the protozoan parasite, Trypanosoma cruzi. Sixteen to eighteen million people are currently infected with this organism, and 45,000 deaths are attributed to the disease each year. Infection with T.

REPORT


World Class Parasites VOLUME 7

Volumes in the World Class Parasites book series are written for researchers, students and scholars who enjoy reading about excellent research on problems of global significance. Each volume focuses on a parasite, or group of parasites, that has a major impact on human health, or agricultural productivity, and against which we have no satisfactory defense . The volumes are intended to supplement more formal texts that cover taxonomy, life cycles, morphology, vector distribution, symptoms and treatment. They integrate vector, pathogen and host biology and celebrate the diversity of approach that comprises modern parasitological research.
