Final answer:
The potato-glycerol based medium selective and enrichment for Bordetella pertussis is the b. Regan-Lowe medium.
Step-by-step explanation:
The potato-glycerol based medium selective and enrichment for Bordetella pertussis, the pathogen responsible for pertussis (whooping cough), is known as b. Regan-Lowe medium. This medium contains charcoal, horse blood, and cephalexin or another antibiotic to select for Bordetella pertussis by inhibiting the growth of other bacteria.
While some other media like Bordet-Gengou agar could also be used for isolation of B. pertussis, the Regan-Lowe medium is specifically formulated to enhance the recovery of B. pertussis from nasopharyngeal specimens.
