Porcine Noroviruses Related to Human Noroviruses
|Antiserum||ELISA antibody titer with each VLP antigen (genogroup-genotype)
|Hawaii (GII-1)||Toronto (GII-3)||MD145 (GII-4)||HS66 (GII-4)||Florida (GII-6)||Desert Shield (GI-3)|
|HS66CS (positive control): human convalescent antiserum to human HS66 (GII-4)||1:25,600||1:6,400||1:25,600||1:25,600||1:6,400||1:6,400|
|LL616: pig convalescent-phase antiserum to porcine QW126 (QW101-like, GII-18)†||1:100||1:800||1:400||1:400||1:400||1:10|
|LL368 (negative control): preinoculation serum‡||<1:10||<1:10||<1:10||<1:10||<1:10||<1:10|
|MM982 (negative control): preinoculation serum‡||<1:10||<1:10||<1:10||<1:10||<1:10||<1:10|
*NoV, norovirus; VLP, viruslike particle; ELISA, enzyme-linked immunosorbent assay.
†The QW126 shared 99% and 100% amino acid identities to the QW101 strain (GII-18) for a 169-bp segment in the RNA-dependent RNA polymerase region and a 363-bp segment in the capsid region, respectively.
‡LL368 and MM982 were sera from 2 gnotobiotic pigs before inoculation with porcine NoVs.
