Abstract
The concentration of penicillin in cerebrospinal fluid and blood was measured after a single i.m. injection of 1.44 g penicillin G benzathine in 18 individuals (4 with neurosyphilis and 14 with neurological symptoms but not syphilis). Only one person had a treponemicidal concentration in the cerebrospinal fluid.
