| evidence of west nile virus lineage 2 circulation in northern italy. | a west nile virus (wnv) strain belonging to lineage 2 was for the first time detected in two pools of culex pipiens collected in the province of udine and in tissues of a wild collared dove (streptopelia decaocto) found dead in the province of treviso, in north east of italy. it was molecularly identified by group and wnv lineage specific rt-pcrs and characterized by partial sequencing of the ns3 and ns5 genes. when compared with the sequences of same fragments of ns3 and ns5 of the wnv lineage ... | 2012 | 22406344 |
| west nile virus in north-eastern italy, 2011: entomological and equine igm-based surveillance to detect active virus circulation. | since 2008, west nile virus (wnv) has expanded its range in several italian regions, and its yearly recurrence suggests the virus may have become endemic in some areas. in 2011, a new plan based also on the detection of igm antibodies was implemented in the north-eastern italian regions of veneto and friuli venezia giulia, aiming to early detect wnv infections in areas where the virus had already circulated during the previous summers, and in adjacent zones. from july to november 2011, 1880 sera ... | 2013 | 22971022 |
| experimental infection of eurasian collared-dove (streptopelia decaocto) with west nile virus. | the eurasian collared-dove (streptopelia decaocto) has recently experienced a population explosion in north america. it is frequently infected with west nile virus (wnv). to test the hypothesis that the eurasian collared-dove is competent to transmit wnv, we experimentally infected two cohorts of doves with two different strains of wnv, co08, and ny99, respectively. both virus strains induced a low-level viremia, capable of infecting a small fraction of vector mosquitoes. we suggest that the eur ... | 2013 | 24581347 |
