Abstract: To our knowledge, this report describes the first case of Actinomyces turicensis lung abscess in the English-language literature. A female patient presented complaining of a cough for 3 weeks. She was found to have a pulmonary abscess, and her culture demonstrated Actinomyces turicensis. This organism usually colonizes the genitourinary tract and skin, therefore, isolation of this bacterium from the lung suggests that the oropharynx may be an emerging site of colonization. Clinical suspicion of Actinomyces infection needs to be communicated to the laboratory to optimize detection techniques, including growth media and duration of incubation, as correct diagnosis is crucial for appropriate antibiotic treatment.
