Hea contains indicators of lactose fermentation and hydrogen sulfide production; Selective isolation of salmonella and shigella. Hektoen enteric agar (hea) was developed in 1967 by king and metzger of the hektoen institute in order to improve the isolation of shigella and salmonella organisms when compared with other media frequently utilized at that time.1,2 this medium is considered to be moderately selective, and is particularly useful in the isolation of shigella.
