| genetic and phenotypic characterization of borrelia burgdorferi strains isolated from ixodes ricinus ticks in the province of bolzano, italy. | lyme disease is caused by three borrelial species, b. burgdorferi sensu stricto, b. garinii and borrelia group vs461. in a restricted biotope of the bolzano province, in the caldaro community, five clones of two borrelial variants were isolated from ixodes ricinus ticks. a preliminary serological study showed that the two variants cross-reacted with b. burgdorferi b31 and b. garinii n34 strains, respectively. the isolates were genomically related with strains b31 and n34, respectively, sharing a ... | 1995 | 7603344 |
| classification tree methods for analysis of mesoscale distribution of ixodes ricinus (acari:ixodidae) in trentino, italian alps. | cases of lyme disease and tick-borne encephalitis were recognized recently in the province of trento, italian alps. assessment of areas of potential risk for these tick-borne diseases is carried out by a model based on classification and regression trees (cart), using both discrete and continuous variables. data on ixodes ricinus (l.) occurrence resulted from extensive sampling carried out by standard methods in 99 sites over an area of approximately 2,700 km2 in the province of trento. a series ... | 1996 | 8961635 |
| antigenic and genomic analysis of a borrelia burgdorferi sensu stricto strain isolated from ixodes ricinus ticks in alto adige-south tyrol, italy. | a borrelia burgdorferi sensu lato strain isolated from ixodes ricinus ticks in alto adige-south tyrol (northern italy) was analyzed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (sds-page) of whole cell proteins, western immunoblotting analysis (wba) with polyclonal and monoclonal antibodies, and pulsed-field gel electrophoresis (pfge). the isolate named bz6 was identified as belonging to the genospecies b. burgdorferi sensu stricto on the basis of its protein profile and its reac ... | 1998 | 9744686 |
| lyme disease in italy, 1983-1996. | this paper is a brief review of the epidemiology of lyme disease in italy. the first case of the illness was identified by crovato in liguria in 1983. in the following years, many other cases have been reported from all italian regions with the exception of valle d'aosta, basilicata and calabria. the exact number of cases in our country is not known because lyme disease was not a notifiable disease until 1990, but on the basis of literature data, at least 1324 cases have been observed in the fou ... | 1998 | 9812324 |
| tick-borne encephalitis virus in northern italy: molecular analysis, relationships with density and seasonal dynamics of ixodes ricinus. | ixodes ricinus ticks were collected from dragging vegetation and from shot roe deer in the province of trento and belluno in northern italy. ticks were pooled for analyses and from 1060 pools of ticks collected in the province of belluno and 12390 tick samples collected in trentino, four proved positive by immunofluorescence microscopy using a tick-borne encephalitis (tbe)-specific antiserum. the identity of the virus isolates was determined by rt-pcr cycle sequencing and they were all found to ... | 2001 | 11583449 |
| geographical information systems and bootstrap aggregation (bagging) of tree-based classifiers for lyme disease risk prediction in trentino, italian alps. | the risk of exposure to lyme disease in the province of trento, italian alps, was predicted through the analysis of the distribution of ixodes ricinus (l.) nymphs infected with borrelia burgdorferi s.l. with a model based on bootstrap aggregation (bagging) of tree-based classifiers within a geographical information system (gis). data on l ricinus density assessed by dragging the vegetation in 438 sites during 1996 were cross-correlated with the digital cartography of a gis, which included the va ... | 2002 | 12061445 |
| [ixodes ricinus, transmitted diseases and reservoirs]. | the tick ixodes ricinus has been recorded in most italian regions especially in thermo-mesophilous woods and shrubby habitats where the relative humidity allow the tick to complete its 3 year developmental cycle, as predicted for the european climatic ranges. this tick acts both as vector and reservoir for a series of wildlife zoonotic pathogens, especially the agents of lyme diseases, tick borne encephalitis and human granulocytic ehrlichiosis, which are emerging in most of europe. to assess th ... | 2004 | 15305699 |
| seroprevalence study of tick-borne encephalitis, borrelia burgdorferi, dengue and toscana virus in turin province. | tick borne encephalitis virus (tbev) is present in some european countries and it is transmitted by a tick bite. ixodes ricinus is the main vector of the infection in italy, where fortunately clinical neurological manifestations, typical of the more serious phase of the disease, are very rarely observed. this behaviour is different from other endemic euroasiatic areas where numerous cases of encephalitis are described. however tbe transmission has not been widely investigated in italy and availa ... | 2007 | 16312014 |

| genospecies of borrelia burgdorferi sensu lato in ixodes ricinus ticks from the autonomous province of trento, italy. | sequences of the variable intergenic spacer region 5s (rrfa) 23s (rrlb) rrna were used to identify borrelia genospecies present in ixodes ricinus nymphs collected from the lamar lakes area of the province of trento, italy (overall prevalence=6.3%). four genospecies were identified, one for the first time in this province (b. valaisiana), and three which have been noted previously (b. afzelii, b. garinii, and b. burgdorferi s.s.). in order to compare the genetic variability of these genospecies i ... | 2007 | 17137840 |
| prevalence and genetic variability of tick-borne encephalitis virus in host-seeking ixodes ricinus in northern italy. | tick-borne encephalitis (tbe) is a severe disease that has been endemic in north-east italy since 1992. over the past two decades, there has been an increase in the number of human cases reported in many european countries, including italy. to assess the current tbe infection risk, questing ticks were collected from known tbe foci, as well as from a site in northern italy where no human infections have been reported previously. a total of 1739 ixodes ricinus (1485 nymphs and 254 adults) was coll ... | 2009 | 19675189 |
