Figure 2: (a) The effect of B. bronchiseptica LPS on nasal septum respiratory epithelium compared to control explants. Dead cells (DC), vacuolation (VAC), infiltration of PMN (PMN), desquamated cells (DES), and goblet cell activity (GC) are indicated. Bars with different letters have statistical difference with significance level of 95% (). (b) Nasal septa respiratory epithelium exposed to B. bronchiseptica LPS. Epithelial cell death (arrow) on a 100x magnified semithin section is shown. (c) B. bronchiseptica LPS-treated fetal rabbit nasal septum respiratory epithelium. Positive goblet cell cytoplasm is shown by 40x magnified lectin histochemistry. (d) Negative control fetal rabbit nasal septum respiratory epithelium not exposed to B. bronchiseptica LPS. A 100x magnified lectin histochemistry is shown.
