Figure 3From: Experimental co-infection of variant infectious bursal disease virus and fowl adenovirus serotype 4 increases mortality and reduces immune response in chickensTissue viral loads of FAdV and cloacal swabs of chickens in different groups. Chickens were inoculated with variant IBDV-ZD-2018–1 and/or FAdV-4-HB1501. Cloacal swabs were performed, and the viral loads of FAdV in various tissues were measured. a,bBars with different superscripts are significantly different (p < 0.05).Back to article page
