Streptomyces of Actinomycetes Infection
Streptomyces are characterised by the stability of their filaments and by the formation of spores on the aerial mycelia and by the formation of spores on the aerial mycelia that project above the surface of the culture medium. With increasing appreciation of the distinction between norcardiae and streptomycetes, it has been realised that both cause actinomycotic abscesses. Because streptomycetes are ubiquitous in soil, infection is attributed to contamination of scratches and penetrating wounds. Mycetomas caused by streptomycetes are indistinguishable clinically from other actinomycetes.
