  1. Control: Eimeria infected birds, Type A and Type G: Eimeria infected birds challenged with respectively a commensal C. perfringens type A strain (JIR4857) or pathogenic C. perfringens type G strain (CP56). NE: birds without (No) or with (Yes) necrotic enteritis. Gelatinolytic activity of the digested spots is expressed in arbitrary units = \(\frac{100}{{OD/{\text{mm}}^{2} }}\). Data represents mean ± SE. One-way ANOVA followed by Tukey’s multiple comparisons test was used to compare the means of the NE = No groups. Values within the same column with different superscripts differ significantly (p < 0.05).
