    Five anaerobic media were compared in a model blood culture system for their ability to recover small inocula of Gram-negative non-sporing anaerobes. Dehydrated cooked meat medium was the least effective; USP thioglycollate medium was the most effective isolation medium and is recommended for routine use. Freshly prepared cooked meat medium has the advantage of allowing prolonged survival of strains.
