The diagnosis of oropharyngeal gonorrhoea.

Epidemiology There is general agreement that oropharyngeal infection occurs most frequently in homosexual men, followed by women and heterosexual men. The table gives comparative prevalences from four studies of patients with gonorrhoea. Weisner et al4 found the oropharyngeal isolation rate of neisseria species from his population was: N meningitidis 17.2%; N gonorrhoeae 5.6% and N lactamica 1 9%. Young and Bain5 noted that, of gram-negative diplococci cultured, 74.2% were N meningitidis, 20.3% N gonorrhoeae and 3.7% N lactamica.
