From: Detection of seroconversion to West Nile virus, Usutu virus and Sindbis virus in UK sentinel chickens

Figure 1

Neutralization results (PRNT50) obtained for all sentinel chicken sera tested against each of the four viruses and grouped according to age at time of sampling. All chicken sera were coded and all tests were carried out on these coded sera. The codes were revealed only after the results had been presented. The percentages of positive sera recorded at each antibody dilution are shown using a colour scheme; White <1/10; Green 1/10; Yellow 1/20; Orange 1/40; Red 1/80.
