Abstract
Two simplified media for isolating Neisseria gonorrhoeae are described. They differ from the modified Thayer-Martin medium in the enrichment and antibiotics used for preparation. The enrichment for one, enrichment 4 medium, contains only four ingredients, and amphotericin B is used instead of nystatin. This medium is comparable to the modified Thayer-Martin medium for isolating N.gonorrhoeae. It is convenient to prepare and is only one-third the cost of Thayer Martin medium. It is a suitable alternative to the modified Thayer-Martin. The enrichment 5 medium is a hemoglobin-free version of enrichment 4 medium. It is somewhat more selective for contaminants but is also more inhibitory for N. gonorrhoeae.
