A: Gram staining of the isolates from aerobic blood cultures (× 1000 magnification). Numerous long, slightly curved, thin, non-branching, and gram-positive rods were confirmed. B: The development of flat, huge, rough, dry, and white- to light-cream-colored colonies was confirmed. C: The antibiotic disk diffusion susceptibility assay showed susceptibility to vancomycin, macrolides, and quinolones but resistance to amoxicillin and clindamycin. Diffusion results for isolates were based on the M24 Clinical and Laboratory Standards Institute (CLSI) document
