Abstract
The abilities of Transgrow (TG), Thayer-Martin (TM) and New York City (NYC) solid media to maintain viability of 12 strains of Neisseria meningitidis under various controlled conditions were assessed. The effects of charcoal impregnation of swabs, temperature and the presence of CO2 were determined with holding for up to 21 days. Recovery from those samples held at 35C was in almost all instances greater than at 22 or 4C. A strong requirement for CO2 was demonstrated, especially at lower temperatures. No positive effect could be attributed to the use of charcoal-impregnated swabs. NYC and TM media were found to be the best overall, with the former permitting recovery from more than 75% of all samples held on slants after holding for 20 days at 4C in the presence of 5% CO2.
