Isolation and characterization of rare actinomycetes from diverse animal samples.

We isolated 61 actinomycete strains from diverse animal-derived samples. Although Streptomyces predominates in soil environments, actinomycetes recovered from animal samples were primarily non-Streptomyces taxa, including rare genera such as Micromonospora sp. The antimicrobial activities of the isolated actinomycetes were evaluated, and several strains exhibited antibacterial and antifungal activities. These findings highlight animal-derived actinomycetes as promising sources of bioactive natural products.
