致病

Aian influenza irus was isolated from the caecal tonsil, faeces, and kidney of the domestic ducks. The isolated irus was identified as a highly pathogenic H5N1, with a haemagglutinin proteolytic cleaage site deduced amino acid sequence of ... QREKRKKR/GLFGAIAG ... In order to determine the pathogenicity of the isolate, eight 6-week-old specific pathogen free chickens were inoculated intraenously with the irus, and all birds died within 24 h after inoculation.

Six different deletion and insertion mutants of BBSV-X were constructed and these were inoculated to Chenopodium amaranticolor. The preliminary results show that the sat-RNA could enhance symptom of BBSV-X and its insertion mutants on Chenopodium amaranticolor, but the pathogenicity of the CP deletion mutants was reduced.

构建了BBSV-X基因组6个缺失和插入突变体，将它们的体外转录物单独或与sat-RNA一起混合接种苋色藜，初步实验结果表明，sat-RNA能增强全长BBSV-X基因组及含全长基因组的突变体对苋色藜所致的症状，但减轻CP缺失突变体的致病性。
