[Demonstration of pathogens in lymphogranuloma inguinale. An electron microscopy study]

A case of lymphogranulomatosis inguinalis is reported, in which the definite diagnosis was made by the electronmicroscopical demonstration of Chlamydia lymphogranulomatosis in the lymphnode. The value of this diagnostical method is discussed in regard to verifying the diagnosis and in comparison with other methods. The lifecycle of the Chlamydia lymphogranulomatosis could be demonstrated electronmicroscopically. Its exceptional position in microbiological classification is discussed.
