The discovery of
Toxoplasma gondii
independently by Nicolle and Manceaux (1908) and Splendore (1908) was
to open a “Pandora’s Box” that has led research on this parasite into a number of scientific disciplines. In the 100
years since its discovery, the mystery surrounding
T. gondii and its inter-relationship with humans has continued
to provide a stimulating source of material in many areas of research, resulting in the publication of almost 20,000
papers and a number of books. This flood of diverse information shows no sign of abating, with an average of 10
papers per week appearing in PubMed. Herein, it is impossible to do more than provide a very superficial comment
on what has become a massive body of scientific information.
T. gondii has many unique features and seems to be the
“exception to almost every rule” thus acting as a focus for research in disciplines from epidemiology to immunology
to human behaviour to cell biology to human disease. In this review a number of the historical advances will be
mentioned and combined with a description of the basic biology of the parasite.
