A method of detecting the presence of Neisseria gonorrhoeae in a sample. The method involves detecting a first target sequence taken from the NGO1642 gene and/or a second target sequence taken from the NGO1012 gene. The method may involve a step of amplifying the target sequence, and may involve hybridising the target sequence to a nucleic acid probe and identifying hybridisation. The method may involve simultaneous detection of other target sequences, e.g. from other pathogens.
