“…Two members of the B. burgdorferi complex, B. garinii and B. afzelii, circulate in this zone with approximately equal frequencies (Postic et al 1997, Alekseev et al 1998, Dubinina and Alekseev 1999.…”

Abstract. A total of 7210 unfed adult Ixodes persulcatus Schulze, 1930 and I. ricinus (L., 1758) ticks were collected from the vegetation by flagging in 35 study sites located in the zone of their sympatry (mainly in Leningrad region, Russia). Borrelia infection in ticks was estimated by the dark-field microscopic analysis of gut contents in standard vital preparations at a magnification of ×600. No correlation was revealed between the series of parameters characterising the abundance of each tick species (τ = -0.13) and between the series of these parameters and the prevalence of Borrelia in each vector. It is concluded that in the broad zone of I. persulcatus and I. ricinus sympatry, the presence and proportion of one vector in the ecosystem does not have any significant effect on the extensity of infection and on the epizootic and epidemic significance of the other vector. Each tick species has its independent (of the other species) and relatively original functional role in the focal ecosystem.

“…In this area, the I. persulcatus tick is the only vector transmitting these infections to humans (1,2,9,10). Only two Borrelia species (B. garinii and B. afzelii) circulate in this area, but the frequency of B. garinii in ticks, rodents, and patients is substantially higher (11). Each year, unfed adult ticks were collected from vegetation in several areas where people are exposed to ticks.…”

“…Borrelia burgdorferi sensu lato is now known to include at least 5 genospecies associated with I. ricinus: Borrelia burgdorferi sensu stricto, Borrelia garinii, Borrelia afzelii, Borrelia valaisiana (formerly genospecies VS116), and Borrelia lusitaniae (formerly genospecies PotiB2) (Baranton et al 1992;Canica et al 1993;Postic et al 1994Postic et al , 1997Le Flè che et al 1997;Wang et al 1997). The geographical distribution of I. ricinus covers southern Scandinavia, the British Isles, Central Europe, France, Spain, Portugal, Italy, the Balkans, East Europe, northern Iran, and North Africa Rodhain 1977, Stanek et al 1988).…”

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.
