The aim of this study was to identify aerobic actinomycetes strains belonging to genera and species rarely encountered in infections. Clinical specimens (sputum, gastric fluid and abscess pus) are collected from patients with symptoms of tuberculosis, pneumopathy, septicemy or having abscess, hospitalized in different services of infectious diseases in Constantine University Hospital Center, East of Algeria. A total of 49 strains of aerobic actinomycetes were isolated; among which 40 ones belong toStreptomyces, Nocardia and Actinomadura genera; however, nine strains are members of other actinomycetes genera, characterized in this study. Phenotypic, chemotaxonomic proprieties and sequencing 16S rRNA gene established identification of these isolates to:Nonomuraea roseolaKribbella sp., Micromonospora aurantiacaNocardiopsissynnemataformans and Saccharothrix longispora. Identified isolates belonged to genera and species rarely encountered in clinical specimens; their role in pathology must be defined.


Key words: Uncommon aerobic actinomycetes, clinical specimens, polyphasic taxonomy.
