Seroconversion rates in surviving birds.

*Sp = Species (CK = Chicken, DK = Duck, SPR = Sparrow); SR = Seroconversion Rate in surviving birds (%); NA = Not Applicable.†All values appearing in the # column correspond to the 7 different experiments described in Table 1: A = Sparrows' ability to transmit H5N1 infection to each other when freed in the isolator (A.1) or caged (A.2.); B.1 & B.2 = Sparrows' ability to transmit H5N1 infection to chickens when freed in the isolator (B.1) or caged (B.2); B.3 & B.4 = Chickens' susceptibility to H5N1 when inoculated with 105.23 EID50, dose determined as representing the total amount of virus shed by 24 infected sparrows during one hour through their feces, through direct inoculation (B.3.) or through exposure to contaminated water (B.4); C = Sparrows' ability to be contaminated through contact with infected ducks.

* 物种（Species），缩写：CK=鸡（Chicken）、DK=鸭（Duck）、SPR=麻雀（Sparrow）；SR为存活鸟类的血清转换率（Seroconversion Rate，以百分比计）；NA表示不适用（Not Applicable）。† 所有#列中的数值对应表1中记载的7组独立实验：A. 麻雀在隔离器内自由活动饲养（A.1）或笼养（A.2）条件下的相互H5N1病毒传播能力；B.1与B.2：麻雀在隔离器内自由活动饲养（B.1）或笼养（B.2）条件下向鸡传播H5N1病毒的能力；B.3与B.4：鸡接种10^5.23 EID50（鸡胚半数感染剂量）病毒后的易感性——该接种剂量等同于24只感染麻雀1小时内通过粪便排出的总病毒量，实验分别通过直接接种（B.3）或暴露于受污染水源（B.4）两种方式开展；C. 麻雀通过接触感染鸭子而被病毒污染的能力。
