case_images: (A) Gram stain of Chimaeribacter arupi. The scale bar in the lower left corner corresponds to 10 microm. Gram-negative very pleomorphic rods are observable. (B) Depicted are Chimaeribacter arupi colonies grown on Columbia agar supplemented with sheep blood grown overnight at 36 C. Bacterial colonies are relatively large, mucoid, gray in color with a light yellowish tinge.

case_images: In the Gram stain Chimaeribacter arupi grown at 22 C or 35 C under aerobic atmospheric conditions presents as Gram-negative pleomorphic, non-spore-forming rods with a single cell length of 0.9 microm to 4.6 microm and a width ranging from 0.4 microm to 1.0 microm ( Figure 1A ). With longer incubation time, the colonies become slightly yellowish, show weak hemolysis, and appear mucoid ( Figure 1B ).
