Bile salts are commonly used in selective media for fecal samples to inhibit the growth of gram-positive bacteria while allowing for the growth of gram-negative bacteria, including potential intestinal pathogens. NaCl and peptone are commonly found in general media, while sheep red blood cells and thioglycollic acid are not typically used in selective media for fecal specimens.
