Seroprevalence of Toxoplasma gondii, risk factors and knowledge about toxoplasmosis in undergraduate students from Lima, Peru.

Toxoplasma gondii is the causative agent of toxoplasmosis, a zoonotic disease of worldwide distribution. The aim of this study was to assess the seroprevalence of T. gondii in undergraduate students from Lima, Peru, and to identify the risk factors linked to the infection. For this, serum samples of 100 undergraduate students of the Faculty of Biological Sciences were tested for T. gondii antibodies with a commercially available ELISA. The seroprevalence of T. gondii in these subjects was 7 %. Only the age of students showed a statistical association with T. gondii seropositivity. The level of awareness regarding toxoplasmosis was also investigated. In the sample, 71 % of the students are aware of toxoplasmosis and 64 % that a parasite is the cause of the infection. Most know it is transmitted through undercooked meat (57 %), but are unaware of contaminated vegetables (40 %), organ transplants (17 %), blood transfusions (32 %), and soil contact (39 %). In the epidemiological context it will be valuable to verify toxoplasmosis awareness in other population groups and other regions in Peru.
