[Usefulness of commercial culture media for gonococcal diagnosis in general practice. Comparative study of various test systems]

In comparative investigations under standardized conditions, the gonococcus culture systems distributed by Miles GmbH, Orion Diagnostica GmbH, and Röhm Pharma GmbH were examined with regard to their usefulness for cultural diagnosis of gonorrhea in general practice. It was shown that because of substantial imperfections Microcult GC (Miles) is not suitable for the diagnosis of gonorrhea. Since microorganisms were grown on Biocult (Orion) and Gono-Nährböden (Röhm) which may cause a false-positive diagnosis, as well as microorganisms that may cause a false-negative diagnosis, these products are only of limited value for the venerologist in practice.
