Modified transport and growth medium for the cultivation of Neisseria gonorrhoeae.

Transgrow medium was developed by Martin and Lester (1971) as a combined transport and culture medium for N. gonorrhoeae and N. meningitidis. It has since become widely used in the United States, where it is considered to be an important aid in the diagnosis of gonorrhoea in patients attending clinics which are remote from a laboratory. Certain of the ingredients of Transgrow are difficult to obtain in the United Kingdom and are expensive. The object of this study was to produce and evaluate a modified Transgrow medium using easily available ingredients, achieving the criteria of acceptability laid down by the U.S. Department of Health.
