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.
