Molecular typing of treponema pallidum clinical strains from Lisbon, Portugal.
A molecular system was used to subtype Portuguese Treponema pallidum clinical strains isolated from both skin lesions and blood. The study with this system constitutes the first typing study in a European country. Three T. pallidum subtypes were found: subtypes 14a (50%), 14d (45.2%), and 14f (4.8%). Further studies are needed to better characterize the isolates involved in syphilis outbreaks.
