Fig. 1From: Prevalence of adhesin and toxin genes in E. coli strains isolated from diarrheic and non-diarrheic pigs from smallholder herds in northern and eastern UgandaPost-mortem picture from an 8-week-old diarrheic piglet in northern Uganda. The segments of the jejunum were distended with fluid accumulation (a). Histopathology (b) showed intact jejunal villi, enterocytes and brush border but with cell infiltration of the jejunal epithelium. The bacteria (black arrows) can be seen attached to the brush border, forming a continuous layer. The E. coli strain AIDA/STb/EAST1, O139 was isolated from this pigletBack to article page
