From: A case of recurrent acute cholecystitis caused by Actinomyces odontolyticus, rare actinomycosis
Gram stain of bile revealed gram-positive rods without an elongated radial pattern (red arrow) and gram-positive cocci (black arrow). Later, we identified gram-positive rods as A. odontoliticus and gram-positive cocci as MRSA (magnification × 1000, 300 dpi) (This image was acquired and captured using an Olympus BX51 microscope (Olympus, Japan) and Olympus DP20-5 (Olympus, Japan))
