- DHL Agar (Desoxycholate Hydrogen Sulfide de Lactose Agar) allows optimal growth of Shigella and Salmonella which do not grow well on SS Agar.

- It is also used for the isolation of pathogenic coli.

1. Preparation

Add 63.3 g of dry medium to 1 L of distilled water, mix well and heat to dissolve.

- Distribute 20 mL per Petri dish and leave to solidify before use.

2. Identification

Incubate at 37 °C for 20 hours. Avoid inoculating too much sample, approximately the same amount of sample used
for MacConkey Agar is recommended.

- Lactose, saccharose non-fermenting organisms form colorless transparent colonies relatively larger than those on SS Agar. Lactose, saccharose fermenting organisms form red opaque colonies. So, differentiation between the two organisms is simple.

- Organisms producing hydrogen sulfi de are liable to form black colonies.

2. Remark
