Table 2 Gelatinolytic activity of jejunal samples ofEimeriaandC. perfringenstype A- or type G-infected broilers

From: C. perfringens challenge reduces matrix metalloproteinase activity in the jejunal mucosa of Eimeria-infected broiler chickens

Group NE Gelatinolytic enzyme, approximate MW
~ 40–45 kDa ~ 50–60 kDa ~ 60–70 kDa ~ 75–85 kDa
Control (n = 5) No 1.10 ± 0.054A 1.19 ± 0.072 1.03 ± 0.039 1.09 ± 0.077
Type A (n = 5) No 0.81 ± 0.083B 1.10 ± 0.15 1.05 ± 0.14 1.09 ± 0.18
Type G (n = 5) No 0.74 ± 0.051B 1.01 ± 0.086 0.93 ± 0.063 0.89 ± 0.087
Type G (n = 9) Yes 0.65 ± 0.030 0.98 ± 0.045 0.86 ± 0.051 0.74 ± 0.045
  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).
