Colonisation dynamics of C. jejuni strains in two commercial broiler lines at 4DPI.
Fig 1.
Caecal colonisation of two commercial broiler lines at 11DPI.
Caecal colonisation of two broiler lines, A (closed circles) and B (open circles) by four C. jejuni strains. Bars represent the median value for each group. Asterisks show statistically significant differences in colonisation levels between the two broiler breeds as assessed by Mann Whitney U test (* p = 0.0024).
Fig 2.
Ileal colonisation of two commercial broiler lines at 11DPI.
Ileal colonisation of two broiler lines, A (closed circles) and B (open circles) by four C. jejuni strains. Bars represent the median value for each group. Asterisks show statistically significant differences in colonisation levels between the two broiler breeds as assessed by Mann Whitney U test (** p = 0.079; § p = 0.006; ‡ p = 0.001).
Table 3.
Extra-intestinal spread of C. jejuni to edible tissues at 11 DPI.
Fig 3.
C. jejuni 13126 displays enhanced invasiveness in Caco-2 cells.
Invasion of Caco 2 cells by five C. jejuni strains was examined. Asterisks show statistically significant differences in invasion levels between C. jejuni 13126 and the other four strains as assessed by one-way ANOVA (** p = 0.01).
Fig 4.
Mortality of Galleria mellonella larvae at 48h post infection with C. jejuni.
Mortality as measured by larval viability 48 hours after challenge. Data presented based on six repeats of infection experiment using 10 larvae per isolate. Asterisks show statistically significant differences in mortality rate between C. jejuni 13126 and other strains as assessed by one-way ANOVA with Tukey post-hoc test (* p = 0.02; ** p = 0.001).
