Question

Why is it that although Nocardia spp. grow well on most common nonselective laboratory media, many are missed when the cultures are read

Answer 1

These organisms require 3 to 6 days to grow.

Step-by-step explanation:

Nocardia are a group of actinomycetes. Some of the species of the nocardia are pathogenic to the humans. There are more than 70 species of nocardia in the world.

Some of the Nocardia spp. grow on the most common non laboratory media but many of them are missed out when the cultures are read because these organisms requires at least 3 days to 6 days to grow.
