Smear and culture diagnosis in gonorrhoea.

The subject of the diagnosis of gonorrhoea may be considered under three main headings apart from clinical diagnosis. The first is how far smear diagnosis is reliable and what are its limitations; the second is whether culture methods are superior to or at least adjuvant to direct microscopical observations and, if so, what the best methods may be; and the last to what extent reactions based on immunity supplement the above methods.
