Streptomyces cacaoi, Gram-positive, branched, filamentous bacillus forms without fragmentation, are saprophytic soil organisms rarely known to cause invasive infections other than mycetoma. Here we describe a case of chronic suppurative otitis media caused by Streptomyces cacaoi in a patient with hyperlipidemia in China. A 62-year-old female patient with hyperlipidemia suffered chronic suppurative otitis media caused by Streptomyces cacaoi. She had a favorable outcome with a 4-week course of ofloxacin ear drops. Streptomyces cacaoi is rarely reported to cause human infection. The introduction of molecular techniques improves the ability to identify rare species such as Streptomyces considerably. We report the case improve our ability to identify this pathogen and expand the range of known bacterial causes of human infection.
