Nocardia species typically exhibit distinctive
Nocardia species typically exhibit distinctive colony morphology on blood agar. Here are the common features:
Appearance: Nocardia colonies can vary in appearance but are often described as having a chalky, matte, or velvety surface. They might appear dry and crumbly.
Color: Colonies are usually white to yellow or orange, but the color can vary depending on the species and the medium used.
Texture: The colonies are often adherent to the agar and may exhibit aerial hyphae, giving a fuzzy appearance.
Size: Colonies may grow slowly and take several days to become visible. They can range from small to large, depending on the incubation period.
Shape: Colonies are typically round and may have irregular edges.
