Trypanosoma Vivax En Colombia: Interpretation De Resultados De Campo

Summary

The use of the indirect fluorescent antibody test and complementary blood smear examinations in Colombia has shown thatTrypanosoma vivax infections of cattle may be considered to be distributed throughout the tropical and subtropical areas of the country. However within this distribution the prevalence showed wide variations between herds and localised epidemic situations could occur at the herd and village level. The examination of sequential serum samples from 2 localities has given additional information on incidence and on transmission patterns.

Résumé

En utilisant l'épreuve de recherche des anticorps fluorescents complétée par l'examen d'étalement de sang, en Colombie, il a été montré que l'infection du bétail parTrypanosoma vivax peut-être considérée comme généralement répandue dans toutes les régions à caractère tropical et subtropical du pays. Cependant à l'intèrieur même de cette extension il existe de larges variations entre les troupeaux et des épidémies à caractére local peuvent exister au niveau des troupeaux et des villages. L'examen de séries d'échantillons de sérums en provenance de deux localités a donné des informations complémentaires sur l'incidence de la maladie et les formes de sa transmission.

Resumen

Mediante la técnica indirecta de anticuerpos fluorescentes y el examen complementario de frotis sanguíneos se demostró, que elTrypanosoma vivax se encuentra distribuido en las áreas subtropicales y tropicales de Colombia. No obstante, dentro de esta distribución, la prevalencia es variada dentro de hatos, pudiendo ocurrir brotes epidémicos localizados. El análisis de muestras serológicas de 2 localidades efectuadas a intervalos diferentes, han arrojado información adicional sobre la incidencia y modo de transmisión.
