| low risk of lyme borreliosis in a protected area on the tyrrhenian coast, in central italy. | a comprehensive lyme borreliosis risk assessment process was applied in s. rossore estate, on the tyrrhenian coast, near pisa, italy. host-seeking ixodes ricinus nymphs peaked in may in oak-dominated deciduous wood (median, q1-q3, number of nymphs/50 m dragging = 4.5, 2.5-8), whereas host-seeking larvae peaked in august in the same habitat type (6.0, 4-17/50 m dragging). prevalence of i. ricinus infestation was 88.9% in wild rodents (n = 11), 64.3% in fallow deer (n = 28) and 0.0% in wild boars ... | 1999 | 10414379 |
| 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 |
| borrelia lusitaniae in immature ixodes ricinus (acari: ixodidae) feeding on common wall lizards in tuscany, central italy. | lizards and small rodents were live captured in tuscany, central italy, from may through august 2005. prevalence of infestation by larval ixodes ricinus l. (acari: ixodidae) and mean numbers of larvae per host were not significantly different for common wall lizards, podarcis muralis laurenti, and apodemus spp. mice, whereas infestation levels by nymphs were significantly greater on lizards. borrelia lusitaniae, which was previously shown to be dominant in host-seeking i. ricinus in the same stu ... | 2007 | 17427701 |
| temporal variations in the usefulness of normalized difference vegetation index as a predictor for ixodes ricinus (acari: ixodidae) in a borrelia lusitaniae focus in tuscany, central italy. | host-seeking ticks were collected during monthly dragging sessions from november 2004 through october 2006 in tuscany, central italy. normalized difference vegetation index (ndvi), which was calculated from landsat etm+ 7 remote sensing data recorded in august 2001, was significantly correlated with numbers of host-seeking immature ixodes ricinus l. (acari: ixodidae) during periods of relatively low rainfall such as summer 2005 (spearman's p = 0.78, p < 0.001 for nymphs in july) and to a lower e ... | 2008 | 18533451 |
| anaplasmosis in cattle in italy. | bovine anaplasmosis caused by anaplasma marginale is a disease transmitted by ticks belonging to the ixodidae family. southern italy is considered an endemic zone but environmental and social factors are changing the epidemiology of the disease to expand to previously anaplasmosis-free regions. the available data of published reports of anaplasmosis in italy together with the data obtained by the national centre of reference for anaplasma, babesia, rickettsia and theileria (c.r.a.ba.r.t.), allow ... | 2007 | 17682850 |
| borrelia lusitaniae and spotted fever group rickettsiae in ixodes ricinus (acari: ixodidae) in tuscany, central italy. | prevalence of infection by borrelia burgdorferi s.l. and spotted fever group (sfg) rickettsiae was estimated in host-seeking ticks in an area in tuscany, central italy, where lyme borreliosis was reported in a forestry worker. b. burgdorferi s.l. was identified by polymerase chain reaction in 16.7% (95% ci = 10.3, 24.8) of ixodes ricinus (l.) nymphs and 39.6% (95% ci = 26.5, 54.0) of adults. borrelia lusitaniae accounted for 82.9% of positive samples, followed by borrelia garinii (9.8%), borreli ... | 2006 | 16619594 |
| prevalence and incidence of antibodies to borrelia burgdorferi and to tick-borne encephalitis virus in agricultural and forestry workers from tuscany, italy. | the ticks ixodes persulcatus and ixodes ricinus are the main vectors of both borrelia burgdorferi sensu lato and tick-borne encephalitis (tbe) virus in eurasia. borrelia burgdorferi is the cause of lyme borreliosis, and tbe is a biphasic meningoencephalitis induced by an arbovirus belonging to the flavivirus family. the principal aims of the current investigation were (i) to determine the frequency of serological evidence of borrelia burgdorferi sensu lato and tbe infections in healthy agricultu ... | 2005 | 15948001 |
| transmission dynamics of borrelia lusitaniae and borrelia afzelii among ixodes ricinus, lizards, and mice in tuscany, central italy. | to estimate the basic reproduction number (r(0)) of borrelia lusitaniae and borrelia afzelii, we formulated a mathematical model considering the interactions among the tick vector, vertebrate hosts, and pathogens in a 500-ha enclosed natural reserve on le cerbaie hills, tuscany, central italy. in the study area, ixodes ricinus were abundant and were found infected by b. lusitaniae and b. afzelii. lizards (podarcis spp.) and mice (apodemus spp.), respectively, are the reservoir hosts of these two ... | 2011 | 20482342 |
