Blastocystosis and other intestinal infections by eukaryotic parasites of Gallus gallus domesticus in localities of southern Chile
Descripción del Articulo
The purpose of this investigation was to determine the presence and prevalence of blastocystosis, a zoonosis caused by Blastocystis sp in free-range hens in homes of different localities in southern Chile, simultaneously verify human infection in at least one locality, and identify other infections...

The purpose of this investigation was to determine the presence and prevalence of blastocystosis, a zoonosis caused by Blastocystis sp in free-range hens in homes of different localities in southern Chile, simultaneously verify human infection in at least one locality, and identify other infections by intestinal parasites in birds. Fresh fecal samples from hens and humans were collected and preserved in PAF fixative and processed by the PAFS method combined with a flotation phase with zinc sulfate solution. Blastocystis sp was detected in half of the homes and the average prevalence was 14.2% in the total of localities being greater in the rural area and in the locality of Teupa (p<0.05). The prevalence in humans was higher than in hens in the town of Ñancul (p<0.05), where the parasite was present in both hosts in 4 of 7 households. The prevalence of infection by Entamoeba gallinarum and the presence of Toxocara spp eggs was similar between localities, but the prevalences of Eimeria spp, Capillariidae gen. spp and Heterakis gallinarum / Ascaridia galli showed differences between localities (p<0.05). Only in Valdivia were observed samples with eggs of Trichostrongylidae gen. spp. The presence of blastocystosis in chicken was detected for the first time in Chile, suggesting its potential transmission to humans. The presence of Toxocara spp eggs in bird faeces suggests that they could act as environmental dispersers. El propósito de esta investigación fue determinar la presencia y prevalencia de blastocystosis, zoonosis causada por Blastocystis sp, en gallinas criadas libremente en domicilios de localidades del sur de Chile. Las muestras de heces frescas de aves y humanos fueron colectadas con el fijador PAF y procesadas mediante el método del PAFS combinado con una fase de flotación con solución de sulfato de zinc. En la mitad de los domicilios se detectó Blastocystis sp en las aves con una prevalencia promedio de 14.2%, siendo mayor en la zona rural y en la localidad de Teupa (p<0.05). La prevalencia en humanos fue mayor que en las gallinas de la localidad de Ñancul (p<0.05), donde el parásito estuvo presente en ambos hospederos en 4 de 7 domicilios. La prevalencia de infección por Entamoeba gallinarum y presencia de huevos de Toxocara spp fue similar entre localidades, pero las prevalencias de Eimeria spp, Capillariidae gen. spp y Heterakis gallinarum / Ascaridia galli mostraron diferencias entre localidades (p<0.05). Solo en Valdivia se registraron muestras con huevos de Trichostrongylidae gen. spp. La presencia de blastocystosis en gallinas se detecta por primera vez en Chile sugiriéndose su potencial trasmisión hacia los humanos. La presencia de huevos de Toxocara spp en las heces de las aves sugiere que estas podrían actuar como dispersores ambientales. |
