Final answer:
Leptospira culture media are specific types of media used to culture and grow the bacteria Leptospira. TCBS (Thiosulfate Citrate Bile Salts) is a selective and differential medium commonly used for the growth of Vibrio spp., including some species of Leptospira. The correct option is b.
Step-by-step explanation:
Leptospira culture media are specific types of media used to culture and grow the bacteria Leptospira.
One of the options listed, TCBS (Thiosulfate Citrate Bile Salts), is commonly used as a selective and differential medium for the growth of Vibrio spp., including some species of Leptospira. It contains bile salts and other compounds that inhibit the growth of many bacteria, making it selective for Vibrio spp.
It also contains thiosulfate and citrate, which allows for the differentiation of fermenters and non-fermenters based on their ability to utilize these compounds. The correct option is b.
