摘要: To investigate whether ticks of the genus Ixodes are infected by Borrelia burgdorferi complex, 490 unfed ricinus were collected flagging in three different areas Tunisia 1998. DNAs extracted from 81 adults, 60 nymphs and 38 larvae analysed after genic amplification noncoding spacer between two copies rrl–rrf genes B. sl. The prevalence was found to be 34, 33.3 2.6%, respectively. All (n = 61) but one identified as belonging genotypes lusitaniae analysis restriction fragment length polymorphism products. In addition, 290 14 7 used inoculate BSK-H medium isolate spirochetes. Fifteen strains isolated adult humid Tunisia, whereas only obtained larvae. Isolates (15/16) garinii (1/16). These results provide new evidence for existence Lyme borreliosis North Africa.
