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. I...

Burkholderia cepacia is a recognised cause of respiratory failure in patients with cystic fibrosis. The value of routine use of selective enrichment broth to increase the yield of B cepacia from cystic fibrosis sputa was investigated. Two hundred sputa from 86 adult and paediatric patients were cultured onto B cepacia selective agar and also in enrichment broth. The enrichment broths were subcu...
