| 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 ... | 2003 | 12860623 |
| serological evidence of rickettsia infections in forestry rangers in north-eastern italy. | the prevalence of antibodies to rickettsiae and other tick-borne microrganisms in the sera of 181 forestry rangers from friuli-venezia-giulia, italy, was examined. seven (3.9%) sera were positive for rickettsia conorii and rickettsia helvetica, as single or dual infections; four of these sera had been found previously to be positive for borrelia burgdorferi. antibodies to coxiella burnetii were detected in five (2.8%) sera, four of which were also positive for b. burgdorferi. these findings indi ... | 2006 | 16643531 |
| detection and identification of rickettsia species in the northeast of italy. | this study was carried out using ixodes ricinus ticks collected during 2005 and 2006 from the friuli venezia giulia (fvg) region in the northeastern part of italy and an area along the slovenian side of the western border of italy. the results indicate that rickettsia spp. is widely distributed throughout these areas, with the greatest prevalence in the central part of the fvg region. the prevalence of rickettsia spp. was 4.5% during 2005 and 6.1% during 2006. by sequencing the 16s rrna gene, we ... | 2008 | 18637720 |
