[Treponema pallidum subspecies pallidum -- the causative agent of neurosyphilis].

Neurosyphilis is defined as infection of central nervous system by Treponema pallidum subspecies pallidum. Neurosyphilis can develop at any stage after initial infec-tion and is reflected in laboratory results. The pathogenesis of neurosyphilis is similar to that of classical form of syphilis. Individuals with persistent abnormalities in the cerebrospinal fluid are at risk of the development of clinical manifestations. Proper understanding of particular forms of neurosyphilis for differential diagnosis is important to determine potential risk of the development of progressive disease in neurology.
