[Chlamydia and sexually transmitted germs. Description and bacteriological diagnosis].

In this article, the author emphasizes the articular complications of genital infections caused by gonococci, mycoplasma and Chlamydia. He describes the laboratory techniques used to isolate, identify on appropriate media and, if need be, assay the serum or joint antibodies for each of these micro-organisms. If it is difficult to determine the aetiology of a particular case of joint pain, one should keep in mind the possibility that an old or recent genital infection may be responsible.
