Virus titers of field-collected samples from WNV-positive American white pelican chicks and test agreement with carcass-matched specimens, Montana, USA, 2006–2007*

Sample No. (%) WNV positive, n = 19 Median viral titer, log PFU/0.5 cm3 (range) κ
Skin† 15 (88.2) 3.6 (1.7–5.0) 0.88
Feather pulp 15 (78.9) 4.9 (1.3–5.6) 0.84
Oral swab 7 (36.8) 1.2 (0.7–2.1) 0.79
Cloacal swab 4 (21.1) 1.5 (0.7–2.7) 0.79
