a study of the presence of b. burgdorferi, anaplasma (previously ehrlichia) phagocytophilum, rickettsia, and babesia in ixodes ricinus collected within the territory of belluno, the years 2000 and 2001, we sampled ticks in order to establish the distribution of ixodes ricinus in the province of belluno; 5987 tick samples from 244 sites throughout the province were gathered, by dragging for a 5-min period. in 40 sites, seasonal variations and cycle stages of the parasites were studied at monthly intervals from march to september. a polymerase chain reaction (pcr) technique was used to identify the tick-infected sites. of 1931 individual ticks, 8.23% were positive for ...200616584324
genetic diversity of bacterial agents detected in ticks removed from asymptomatic patients in northeastern italy.a total of 360 ticks were removed from 353 asymptomatic subjects in belluno province, italy and surrounding areas, from 1998 to 2001. ticks were identified as ixodes ricinus (357), ixodes hexagonus (1), rhipicephalus sanguineus (1), and ixodes ventalloi (1). tick dna was investigated by pcr and subsequent sequencing of amplified products to identity associated bacterial agents. primers targeting different genes of rickettsia (glta and ompa), borrelia (16s rdna, rpob), francisella (16s rdna), and ...200312860623
detection of hge agent-like ehrlichia in ixodes ricinus ticks in northern italy by pcr.little is known about the distribution of human granulocytic ehrlichiosis (hge) in europe and even less is known in italy, where no case of clinically documented hge has been reported. in a previous study we reported the presence of ehrlichia dna in ixodes ricinus ticks from central italy. by the use of an ehrlichia-specific pcr we found that 24% of the ticks were positive. furthermore, we demonstrated a simultaneous coinfection of the same tick by both, borrelia burgdorferi and ehrlichia phagoc ...199810048173
seroprevalence of tick-borne infections in forestry rangers from northeastern italy.the aim of this study was to estimate the seroprevalence of antibodies to borrelia burgdorferi, anaplasma phagocitophilum and tick-borne encephalitis (tbe) virus, and risk factors, in forestry rangers from the friuli-venezia-giulia region in northeastern italy. sera from 181 forestry rangers were examined with two-tiered serological tests for tbe, lyme borreliosis and ehrlichiosis. information about risk factors such as job location, residence, number of tick bites and outdoor leisure activities ...200415606631
