Resumen
[ES]El principal objetivo de este estudio ha sido la búsqueda e identificación de
hemoparásitos en sangre de ave, mediante la realización y estudio de frotis
sanguíneos, además se ha calculado el índice de parasitemia de los individuos
parasitados y se ha establecido la frecuencia relativa de aparición de macrogametos
y microgametos de las especies de Hemosporidios presentes en las muestras
sanguíneas; se ha llevado a cabo una técnica de procesamiento de imágenes con el
fin de realizar recuentos automáticos de eritrocitos. Se han estudiado muestras
sanguíneas de 93 palomas bravías (Columba livia Gmelin, 1789) de 5 lugares
diferentes de la provincia de Jaén (Jamilena, Martos, Torredelcampo,
Torredonjimeno y Villardompardo), de las cuales sólo el 27,96% de las palomas han
presentado hemoparásitos del género Haemoproteus, que desde el punto de vista
morfológico se puede asignar a la especie Haemoproteus columbae (Kruse, 1890).
Los individuos parasitados (n=26) presentan diferentes niveles de parasitemia.
[EN]The main goal of this study has been the detection and characterization of hemoparasites in the blood domestic pigeons (Columba livia Gmelin, 1789) meanwhile the study of blood smears stained with Giemsa stain. We determined the rate of infection in sampled population and calculated the parasitemia rate of parasitized individuals. In the same way, we established the relative frequency of appearance of macrogametes and microgametes of the species of Haemosporidia present in the blood samples. Analytical process has been carried out by a technical image processing for the purpose of to perform the automatic counting of erythrocytes. It has been studied blood samples from 93 domestic pigeons catched in 5 different localities in the province of Jaen (Jamilena, Martos, Torredelcampo, Torredonjimeno and Villardompardo). Only 27.96% of pigeons have blood parasites from genus Haemoproteus, wich from the morphological point of view can be assigned to the species Haemoproteus columbae (Kruse, 1890). The parasitized individuals (n = 26) show different levels of parasitemia.
