A Cross-Sectional Seroepidemiological Study on Infectious Bursal Disease in Backyard Chickens in the Mymensingh District of Bangladesh

Table 1

Interpretation of IBD immune status based on S/P value and ELISA antibody titre.

S/P value	ELISA antibody titre	IBD immune status
S/P ≤ 0.3	Titre ≤875	Negative
S/P > 0.3	Titre >875	Positive

S/P = sample-to-positive, ELISA = enzyme-linked immunosorbent assay, IBD = infectious bursal disease.
