Figure 3. Detection of porcine deltacoronavirus (PDCoV)–specific IgY antibody titers in serum collected from chicks and turkey poults in a study of infection and transmission of porcine deltacoronavirus in poultry. A) Uninfected (n = 6) and infected chicks (n = 6). B) Sentinel chicks (n = 5). C) Uninfected (n = 5) and infected poults (n = 6). D) Sentinel poults (n = 5). OD values are blanked against a control of uncoated wells (carbonate buffer only). Values represent the average of 3 replicates; error bars represent upper half of SEM. Dashed line indicates cutoff, which was determined by using the mean of uninfected birds at 2 dpi +2 SDs. Statistically significant values: *p<0.05; ***p<0.001. dpi, days postinoculation; OD, optical density.
1Preliminary results of this study were presented at the Conference of Research Workers in Animal Diseases, December 1–4, 2018, Chicago, Illinois, USA.
