Summary. Pulmonary infection due to Nocardia sp. was investigated in 600 patients of various bron‐chopulmonary disorders by direct microscopy of sputum samples and cultures on appropriate media. Pathogenic Nocardia species were isolated from 25 patients, giving 4.1% incidence of infection. The species of Nocardia represented were N. asteroides (21 isolates), N. otitidis‐caviarum and N. brasilien‐sis (2 isolates each). Paraffin baiting technique proved to be more efficaceous than culturing on glucose nutrient agar. Zusammenfassung. Von 600 Patienten mit ver‐schiedenen bronchopulmonalen Krankheiten wur‐den Sputumproben direktmikroskopisch und kul‐turell auf Nocardia untersucht. Pathogene Nocar‐dia ‐Arten wurden von 25 Patienten (4,1 %) isoliert. Die isolierten Arten waren: N. asteroides (21 Isolate), N. otitidis‐caviarum und N. brasiliensis (je 2 Isolate). Die Paraffinköder‐Technik erwies sich als wirksamer als die Kultur auf Glucose‐Agar.
