The experimental pathogenicity in Swiss mice of various strains of Nocardia isolated in soil of Tucumán (Argentina).

The isolation of Nocardia pathogenic for man in soil of Tucumán revealed the convenience of undertaking a study of their virulence, to evaluate any potential danger it may imply. Thirty three strains were studied: 28 N. brasiliensis, 3 N. asteroides and 2 N. caviae by inoculating albino Swiss mice into the footpads and intraperitoneally. The results obtained revealed the existence of Nocardia of variable aggresiveness in the soil of Tucumán.

Acid and alkali as aids in differentiation of pathogenic Nocardia and for their isolation from clinical specimens.

The tolerance of Nocardia brasiliensis, Nocardia asteroides and Nocardia caviae to different concentrations of acids and alkalis was studied in this work. The purpose was to determine their use: (a) in the differentiation of species; (b) for decontamination of clinical materials during the isolation of pathogenic Nocardia. The results showed (1) that both 2 M NH3 and 0.05 M H2SO4 solutions are useful for differentiating species. They can also be used as a complementary method for identification. (2) That both 1 M NH3 and 0.05 M H2SO4 solutions were useful for decontamination of clinical materials during the isolation of pathogenic Nocardia.

Localized cutaneous nocardiosis in Japan. A new case.

We report a case of localized cutaneous nocardiosis due to Nocardia asteroides, appearing on the anterior surface of the right forearm of a 29-year-old woman. Examination of the skin revealed a firm subcutaneous nodule measuring 32 x 20 mm and accompanied with a small ulcer. The histology of the lesion showed granulomatous changes interspersed with large numbers of polymorphonuclear leukocytes. On Gram staining, a few bacillary bodies were found scattered through the lesion, but no grains were detected. The classification of the clinical types of cutaneous nocardiosis is discussed, and the Japanese literature on localized cutaneous nocardiosis is examined.

Nocardia asteroides primary cerebral abscess and secondary meningitis.

A rare case of primary cerebral abscess due to Nocardia asteroides, and its surgical removal, are described. Postoperative meningitis caused by the same fungi was succesfully cured with sulphadiazine and cycloserine. The nocardial disease, its neurological complications, and therapy are reviewed.
