RESUMO
Se informa el hallazgo de cultivos puros de n. asteroides a partir de la colección purulenta obtenida por drenaje quirúrgico de un absceso en base pulmonar derecha, de 6 cm de diámetro, en una niña de 13 años de edad con desnutrición de segundo grado y antecedentes de tuberculosis. Lo prolongado de la evolución diagnóstica, el cuadro infeccioso inespecífico, y el probable deterioro inmunológico pudieron haber producido cierta demora en el diagnóstico y por lo tanto para el desenlace fatal

This is the first study initiated in Argentina to establish the presence of species of Nocardia from soil samples. These samples were gathered in different areas of Tucumán. Thirty three pathogenic strains of Nocardia were isolated by the paraffin bait method. Out of them, 28 were N. brasiliensis, 3 N. asteroides and 2 N. caviae. N. brasiliensis was widely distributed in the soil of the areas tested. It is proved that N. caviae, so rarely found in other regions of the world, occurs in Tucumán. A detailed study of the morphological and physiological characteristics for identification is discussed.

The analysis of 19 physiological properties of 28 strains of Nocardia brasiliensis isolated from soil reveal differences which could be of great value in distinguishing pathogenic from nonpathogenic strains.
