As far as I know it is indeed theoretically possible to catch chlamydia when having contact to infected toilet seats. But for this to happen “fresh” infected secretes in high doses must be present. Chlamydia bacteria do not survive for long outside of a body.
Therefore an infection on this way is very unlikely and such a case hasn’t been reported.
For women an infection with chlamydia is especially dangerous since typical symptoms are often lacking. But leaving it untreated can pose significant hazards such as cancer and loss of fertility.
So, get yourself checked regularly.

Danke, ich habe die Bedeutung schon herausgefunden. ;)
Ich fand bloß die Anzeigen daraufhin sehr witzig.
Übrigens: im Duden existiert kein expliziter Eintrag für “Gschmarri”.
