HE agar can be used for the primary plating of fecal specimens. It may also be used to subculture the overnight growth from enrichment broths (such as gram-negative broth or selenite broth) inoculated with fecal specimens suspected of containing low numbers of Salmonella. Direct inoculation of colonies from agar plates may produce sufficient growth of organisms that would otherwise be inhibited in a more dilute inoculum from diarrheal feces or broth culture.
