Development of an Improved Selective Agar Medium for

14 03 2003Although Y pestis can generally tolerate the levels of selective substances used in CIN agar only a portion of the plated bacteria grow to form colonies (1 23) It thus appears that the formulations of selective agents at the levels used in CIN and MacConkey agars cause a decrease in growth rate that results in a lower recovery of Y pestis
