The partial nucleotide sequences of the hemagglutinin (HA) genes of 72 H9N2 influenza viruses isolated from chickens and turkeys in Israel during the period 2000-2005 were genetically analyzed. The isolates possessed the three types of amino acid motif -R-S-S-R/G-L-, -R-S-N-R/G-L-, and -R-S-K-R/G-L- at the cleavage site of HA. Phylogenetic analyses showed that all Israeli isolates belonged to the same group which further divided into three closely related sub-groups. The HA genes of these isolates were related to the HA gene of A/chicken/Germany/R45/98 isolated from chicken in Germany in 1998.
对2000年至2005年期间从以色列鸡和火鸡中分离出的72株H9N2流感病毒的血凝素（HA）基因的部分核苷酸序列进行了遗传分析。这些分离株在HA裂解位点具有三种氨基酸基序——-R-S-S-R/G-L-、-R-S-N-R/G-L-和-R-S-K-R/G-L-。系统发育分析表明，所有以色列分离株属于同一组，该组进一步分为三个密切相关的亚组。这些分离株的HA基因与1998年从德国鸡中分离出的A/鸡/德国/R45/98的HA基因相关。
