  Se describen algunas patologías halladas en una faena de 158ñandúes. Al 40% de las aves se le efectúan hisopados intesti-nales y de vesícula biliar, enviándolos al Área de Patología yProducción Avícola, Facultad de Veterinaria, Uruguay (FV).Los hisopos son transportados en medios de pre-enriqueci-miento, procediéndose según la rutina para enterobacterias. Esaislada una cepa de Salmonella newport. Se seleccionaron seishígados, remitiendo los mismos al Laboratorio de Tuberculo-sis de la DILAVE “Miguel C. Rubino”. Los materiales fueroninoculados, previa descontaminación, en medios selectivos.Se efectúa tinción de Ziehl-Neelsen, pruebas culturales y bio-químicas e identificación por el método de Runyon. Tres ma-teriales presentan lesiones granulomatosas; cinco son bacilos-copía positiva (Bacilos Ácido Alcohol Resistentes), y se aís-lan cuatro Mycobacterium avium y un M. intracellulare. AlLaboratorio de Parasitología (FV) son enviados 17 tractos di-gestivos, sometiendo el contenido a sucesivas sedimentacio-nes, hallándose: Deletrocephalus dimidiatus, Monoecocestussp. y un cestodo aún no identificado. En las plumas es halladoel piojo Struthiolipeurus.. Se enfatiza la importancia quetiene en salud pública la presencia de Mycobacterium y Salmo-nella. Por otra parte los parásitos enumerados plantean la ne-cesidad de su control.

  The result of pathologic findings in 158 ñandúes slaughteredunder official supervision is presented. Swabs from 40 % ofthe birds were obtained from intestinal tracts and gall bladders.Salmonella newport was isolated from them. Six livers wereselected, three of them with granulomatous lesions. They weresent to the Tuberculosis Laboratory in the DILAVE “Miguel CRubino”. The samples were decontaminated and inoculated inselective media. A sample from each of the growing colonieswas stained with Ziehl-Neelsen and biochemical and culturaltests were done for identification with the Runyon method. Inthree samples of them granulomatous lesions were present. Infive of them Mycobacterium were observed through Acid-fastpositive smears. Four samples were positive to Mycobacteriumavium and in one of them M. intracellulare was isolated too.From 17 complete intestinal tracks sent to the ParasitologyDepartment (FV) the following helminthes were found:Deletrocephalus dimidiatus, Monoecocestus sp. and anunidentified cestoda. From feathers a louse identified asStruthiolipeurus sp. was found . Because of the importance ofthe bacteriological findings for public health, special care mustbe taken in the future during the rearing period and duringslaughter to avoid risks. Also, the recorded parasites rise thenecessity of their control during rearing.
