Actinomyces species are filamentous, branching, gram-positive, pleomorphic non-spore-forming, non-acid-fast anaerobic or microaerophilic bacilli. On Gram stain, Actinomyces cannot be distinguished from Nocardia.7 However, Nocardia grow aerobically and stains with acid-fast technique and Actinomyces does...

Gram stain of the excised sample reveals gram variable filamentous rods. Therefore, it should be distinguished from Nocardia and Streptomyces. On an anaerobic culture, Actinomyces meyeri forms creamy-white, moist, confluent colonies on chocolate agar. However, cultures are negative in more than 50%...
. Sinus tracts to the abdominal wall or perianal region can occur. Pelvic actinomycosis was classically associated with intrauterine devices, but has become rare in recent years. Diagnosis is usually made by demonstration of gram-positive filamentous organisms and sulfur granules on histopathology. ...
Clinical specimens were submitted to local microbiology laboratories during 2013-2014 in Alberta, Canada. Samples were initially examined microscopically after Gram staining and cultured aerobically and, if deemed appropriate, anaerobically on typical culture media including sheep blood agar, brain heart in...

The low values of digital DNA-DNA hybridization (10%) were C 16:0 , C 18:1 蠅9 c , and C 18:1 蠅9 c DMA. Based on these data, we propose that strain CtC72 T be classified as a novel species, Actinomyces ruminis sp. nov., under the genus Actinomyces . The type strain is ...
This review focuses on the clinical presentation, cytomorphology and staining characteristics that can be useful in identifying and distinguishing between Nocardia and Actinomyces infections, as well as their mimickers.McHugh Kelsey E.Sturgis Charles D.Procop Gary W.Rhoads Daniel D....
Actinomyces has long filaments that occasionally branch and have a beaded appearance on Wright stain (i.e., variable staining intensity along the filaments) (see Figure 16-8 and Figure 16-11). Actinomyces and Nocardia are pleomorphic organisms that may seem to be a mixed bacterial infection ...
