Hektoen enteric agar is a selective as well as differential media for the isolation and differentiation of enteric pathogens from clinical specimens. The presence of the bile salts and dyes inhibits most gram-positive organisms allowing only gram-negative rods to grow on HE agar.

Hektoen enteric agar (HEK, HE or HEA) is a selective and differential agar [1] primarily used to recover Salmonella and Shigella from patient specimens. HEA contains indicators of lactose fermentation and hydrogen sulfide production; as well as inhibitors to prevent the growth of Gram-positive bacteria.

Jan 4, 2022 · Hektoen Enteric Agar is a selective and differential medium designed to isolate and differentiate members of the species Salmonella and Shigella from other Enterobacteriaceae. The medium was introduced in 1968 by Sylvia King and William I. Metzger.

Sep 20, 2023 · Hektoen Enteric Agar (HE Agar) is a selective and differential agar medium used to isolate and identify Enterobacteriaceae, particularly Salmonella and Shigella. It is a widely used medium in clinical and environmental microbiology.

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.

Remel Hektoen Enteric (HE) Agar is a solid medium recommended for use in qualitative procedures for selective and differential isolation of gram-negative enteric pathogens.

Hektoen Enteric (HE) Agar is a moderately selective differential medium used for the isolation and culture of gram-negative enteric microorganisms, particularly for the isolation of Shigella and Salmonella species from fecal (mixed flora) samples.

Hektoen enteric (HE) agar was developed in 1968 by Sylvia King and William I. Metzger in an effort to increase the recovery of Salmonella and Shigella species over the previously formulated Salmonella-Shigella (SS) Agar.

May 16, 2024 · Hektoen Enteric Agar (HE agar) is a selective and differential medium used in clinical microbiology labs to aid in the recovery and identification of Salmonella and Shigella species from clinical specimens, particularly fecal samples.

Hektoen Enteric Agar is a differential selective medium used for the isolation of Shigella and Salmonella species from enteric pathological specimens. Hektoen Enteric Agar was formulated by Kind and Metzger and meets the requirements of the American Public Health Association (APHA).
