Abstract
Toxoplasma gondii is a protozoan discovered more than a century ago. It is a parasite of great epidemiologic importance which can cause from neurologic complications in the product to fetal death in pregnant women, abortion and encephalitis in patients with AIDS, thus becoming a public health problem in Colombia. In this review of the available evidence, it was concluded that the forms in which the parasite infects human beings are very varied, including the forms known long time ago such as contaminated food, contact with feline feces, as well as other not so well known ways like transfusions, organ transplants, waterborne, and mechanic way, ooquist inhalation and sexual transmission, involving animal species different from felines in the parasite lifecycle, such as dogs and insects. Likewise, the importance of anthropic and environmental factors such as modulators of the transmission dynamics and lifecycle of the parasite are highlighted. This review, provides solid bases for alerting the public health systems about the need to adopt hygienic and sanitary measures to avoid the diffusion of this pathology among high risk populations.
