Prevalence of Borrelia burgdorferi sensu lato genospecies in Ixodes ricinus ticks in Europe : a metaanalysis

摘要: In Europe, Borrelia burgdorferi genospecies causing Lyme borreliosis are mainly transmitted by the tick Ixodes ricinus. Since its discovery, B. has been subject of many epidemiological studies to determine prevalence and distribution different in ticks. current study we systematically reviewed literature on I. ricinus ticks infected with sensu lato. A total 1,186 abstracts English published from 1984 2003 were identified a PubMed keyword search compiled article references. multistep filter process was used select relevant articles; 110 articles 24 countries contained data rates infection Europe (112,579 ticks), 44 21 included species-specific analyses (3,273 positive ticks). These evaluate overall rate genospecies, regional distributions within changes over time, as well influence detection methods rate. While significantly higher adults (18.6%) than nymphs (10.1%), no effect method, gender, or collection period (1986 1993 versus 1994 2002) found. The highest found central Europe. afzelii garinii most common species, but seems vary regions frequent coinfection species for valaisiana.
