UZCATEGUI NEGRON, M et al. Aislamiento de Nocardia asteroides de muestras de suelo de cinco estados de Venezuela . Rev. Soc. Ven. Microbiol. [online]. 2001, vol.21, n.1, pp.17-23. ISSN 1315-2556.

Forty-three soil samples from 25 places ("lugares") in Venezuela were cultivated using the paraffin bait technique for isolation of Nocardia sp. Samples were collected from Lara Sate (19 samples), Mérida State (13 samples), Amazonas State (7 samples), Falcón State (3 samples), and Apure State (1 sample). From the total isolatedstrains, 46.51% were identified as Nocardia asteroides, 16.28% were identified as Nocardia sp. Lara State shows the highest number of N. asteroides isolated (95%), this indicates that Lara State represents one of the most important natural soil reservoir of N. asteroides. The majority of actinomycetoma cases in Venezuela have been reported from this state, where N. asteroides is the second most common etiologic agent of actinomycetoma.
