Abstract
The isolation of an H5N1 Influenza A virus from a tree sparrow (Passer montanus) which we captured in East Java (Sidoarjo) was reported. The analysis showed that the virus titer was 10 ELD 50 and the virus had antigenicity relationships with all the antisera panel derived from clade 21.3, but not with a panel of antisera derived from clade 21.1 that were considered representation of the virus in Indonesia. Based on the result of phylogenetic tree and homology analysis revealed that its haemaglutinin (HA) and neuraminidase (NA) were genetically similar with the virus chiken isolated of East Java 2010 and the virus human isolated from Indonesia in 2006-2007. The sequence revealed that the HA protein cleavage site sequencewas PQRESRRKKR and the sequenceof receptor binding site was QSG. This showed that the virus is classified as High Pathogenic Avian Influenza 5N1, but it could not transmit among human. In the experimental laboratories, it was reported that the pathogenicity of this virus was higher in chicken than in tree sparrow. Thus tree sparrow was more potential to spread this virus than chicken. The finding of a tree sparrow H5N1 virus is genetically similar to the virus isolated from human, thus it is important to always monitor to always monitor the existence of virus in wild birds to anticipate pandemic. Key words: H5N1, Haemaglutinin, Neuraminidase, Tree sparrow
