“…It is also known that Borrelia burgdorferi sensu lato has only been isolated from patients, reservoir hosts, or vector ticks in the Northern hemisphere. In the Southern hemisphere, although positive serologic tests, usually in the form of either ELISA or indirect immunofluorescence assay (IFA), have been reported from Colombia, 10,18 Bolivia, 23 Argentina, 24 Peru, 25 and Africa 26,27 ; however, the spirochete that putatively elicited these antibody responses has not been isolated. In Colombia, serum samples from patients with dermatologic signs, chronic neurologic, and arthritic manifestations, from individuals without clinical signs associated with Lyme borreliosis, were analyzed by Western blot to evaluate the presence of specific IgG antibodies to B. Burgdorferi.…”
