Abstract
We identified 2 poultry workers with conjunctivitis caused by highly pathogenic avian influenza A(H7N3) viruses in Jalisco, Mexico. Genomic and antigenic analyses of 1 isolate indicated relatedness to poultry and wild bird subtype H7N3 viruses from North America. This isolate had a multibasic cleavage site that might have been derived from recombination with host rRNA.
摘要
我们在墨西哥哈利斯科州发现了 2 例由高致病性禽流感 A(H7N3)病毒引起的结膜炎的禽类工作人员。对 1 个分离株的基因和抗原分析表明，其与北美的禽源和野生鸟类亚型 H7N3 病毒有关。该分离株具有多碱性裂解位点，可能源自与宿主 rRNA 的重组。
