“…Additional isolates from I. ricinus are necessary to describe the heterogeneity of spirochetes and the distribution of the various genospecies in southern Europe and North Africa. In sub-Saharan Africa, the existence of B. burgdorferi sensu lato remains unclear, but seems to be improbable because of the absence of ticks of the I. ricinus species complex (Mason et al 1994, Marjolet et al 1995. …”

Free-living adult Ixodes ricinus L. were collected in Amdoun, situated in the Kroumiry mountains in northwestern Tunisia (North Africa). Using direct ßuorescence antibody assay, the infection rate of Þeld-collected I. ricinus by Borrelia burgdorferi sensu lato was 30.5% (n ϭ 72). No difference in infection rate was observed between male and female ticks. Spirochetes that had been isolated from I. ricinus from Ain Drahim (Kroumiry Mountains) in 1988 were identiÞed as Borrelia lusitaniae (formerly genospecies PotiB2). This is the Þrst identiÞcation of a genospecies of Borrelia burgdorferi sensu lato from the continent of Africa.

“…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.…”

In the present study, we report the occurrence of borreliosis in patients from the Brazilian Amazonic region. Nineteen (7.2%) out of 270 dermatological patients with different skin diseases (no one with clinical Lyme disease), tested positive by ELISA for Borrelia burgdorferi. Serum samples from 15 out of the 19 ELISA-positive patients were further evaluated by Western blot. Presence of Borrelia burgdorferi specific IgG was confirmed in eight (53.3%) out of the 15 patients. All eight patients with ELISA and Western blot positive reactions were treated with doxycycline, according to the Centers for Disease Control and Prevention guidelines. One of them had clinical manifestations of colagenosis and was sent to the Department of Internal Medicine for further investigation. Data presented here suggested that borreliosis "lato sensu" is in the Brazilian Amazon region.

“…The spirochete Borrelia burgdorferi sensu lato, which is the etiologic agent of the disease, has only been isolated from patients, reservoir hosts or vector ticks in the Northern Hemisphere or, more precisely, from areas located north of the Tropic of Cancer (Dennis 1995). In the South, positive serologic tests, usually in the form of either the enzyme-linked immunosorbent assay (Elisa) or the indirect immunofluorescence assay (IFA), have been reported from Colombia (Muñoz et al 1995), Bolivia (Ciceroni et al 1994 (Need & Escamilla 1991) and Africa (Schafrank et al 1990, Marjolet et al 1995 but the spirochete that putatively elicited these antibody responses has not been isolated. Moreover, only cases from Brazil included a Western blot (Yoshinari et al 1997) that would comply with the criteria for positivity recently recommended by Dressler et al (1993) and supported by the Centers for Disease Control and Prevention (CDC).…”
