| Abstract: | Histomoniasis was diagnosed in a commercial turkey flock. All morbidity and mortality occurred in one house. Birds exhibited lesions characteristic for histomoniasis, and the diagnosis was confirmed by histopathologic examination. Affected turkeys were infected with moderate levels of Ascaridia dissimilis but not Heterakis gallinarum. Compression smears of hepatic tissues showed typical histotrophic phase Histomonas meleagridis, whereas cecal smears exhibited large numbers of Trichomonas gallinarum. A challenge experiment was conducted in which turkey poults were placed on contaminated litter. Although histomoniasis was not reproduced in the experiment, the birds did become infected with low numbers of A. dissimilis. /// Se diagnosticó histomoniasis en una parvada de pavos comerciales. Toda la mortalidad y la morbilidad ocurrió en un solo galpón. Las aves mostraron lesiones características de histomoniasis y el diagnóstico se confirmó mediante examen histopatológico. Los pavos afectados fueron infectados con niveles moderados de Ascaridia dissimilis pero no con Heterakis gallinarum. Las impresiones de tejidos hepáticos mostraron la fase histotrópica típica de Histomona meleagridis mientras que los frotis cecales mostraron un gran número de de Trichomonas gallinarum. Se realizó un experimento de desafío en el cual se alojaron pavitos sobre cama contaminada. Aunque no se reprodujo la histomoniasis en este experimento, las aves fueron infectaron con números pequeños de A. dissimilis. |
