Seroprevalence of Trypanosoma evansi in dromedaries (Camelus dromedarius) from the Canary Islands (Spain) using an antibody Ab-ELISA

Abstract

After the description in Grand Canary Island of a case of dromedary trypanosomosis caused by Trypanosoma evansi in 1998, an indirect enzyme immunoassay for the detection of specific anti-T. evansi IgG (Ab-ELISA) was used to assess the seroprevalence of this disease on the Canary islands, Seroprevalence was 9.0% in the four studied islands (Gran Canaria, Tenerife, Lanzarote and Fuerteventura), varying from 10.0 to 7.5% by island (not significantly different). Prevalence using Ab-ELISA was higher than that observed when a parasitological method (microscopic observation of blood smears) was used (1.3%). (C) 2000 Elsevier Science B.V. All rights reserved.
