 (ăk-tĭn′ō-mī′sēt, ăk′tə-nō-)
Any of various spore-forming, chiefly filamentous bacteria of the order Actinomycetales that are abundant in soil. Some species produce natural antibiotics, and some are human pathogens.


(Microbiology) any bacterium of the group Actinomycetes, usually filamentous in form
[C20: from actino- + -mycete]
