| 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 |
| 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 |
| [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 |
| temporal variation of ixodes ricinus intensity on the rodent host apodemus flavicollis in relation to local climate and host dynamics. | the risk to humans of contracting tick-borne zoonotic diseases depends on the risk of a bite from an infected tick, which can be broken down into its component parts as the number of host-seeking ticks in the environment, in particular nymphs, and the prevalence of tick-borne pathogens they are carrying. in turn, the prevalence of tick-borne pathogens is dependent upon tick biting intensity on hosts that support transmission between ticks; namely rodents. these ticks once fed moult into the next ... | 2007 | 17760511 |
| early detection of tick-borne encephalitis virus spatial distribution and activity in the province of trento, northern italy. | new human cases of tick-borne encephalitis (tbe) have recently been recorded outside the recognised foci of this disease, i.e. in the province of trento in northern italy. in order to predict the highest risk areas for increased tbe virus activity, we have combined cross-sectional serological data, obtained from 459 domestic goats, with analysis of the autumnal cooling rate based on moderate resolution imaging spectroradiometer (modis) land surface temperature (lst) data. a significant relations ... | 2007 | 18686242 |
| 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 |
| absence of indigenous specific west nile virus antibodies in tyrolean blood donors. | in the last several years, west nile virus (wnv) was proven to be present especially in the neighboring countries of austria, such as italy, hungary, and the czech republic, as well as in eastern parts of austria, where it was detected in migratory and domestic birds. in summer 2010, infections with wnv were reported from romania and northern greece with about 150 diseased and increasingly fatal cases. we tested the sera of 1,607 blood donors from north tyrol (austria) and south tyrol (italy) fo ... | 2011 | 21556676 |
