Fig. 1From: Comparative transcriptome analysis by RNAseq of necrotic enteritis Clostridium perfringens during in vivo colonization and in vitro conditionsHistopathology of duodenum of broilers following chicken intestinal loops inoculated with C. perfringens. H&E-stained paraffin section of a duodenum villus. a: Enterocytes and villi appeared to be well organized in control loops with only TPG broth. b-d: Loops with C. perfringens inoculations, where the cell membranes have broken down and there is an appearance of coagulation necrosis. Large numbers of C. perfringens lining the damaged villi are visible in c and d. Arrows point out C. perfringens. Size bars/magnifications: a and b = 20 μm/X 100; c and d = 5 μm/X400Back to article page
