Expression of type 1 pili by Escherichia coli strains of high and low virulence in the intestinal tract of gnotobiotic turkeys



Expression of type 1 pili by Escherichia coli strains of high and low virulence in the intestinal tract of gnotobiotic turkeys



American Journal of Veterinary Research 46(1): 270-275



Highly virulent (strain 1) and weakly virulent (strain 3) E. coli were examined by immunofluorescent and electron microscopy. 3-week-old gnotobiotic turkeys were killed after 1, 2, 5, 8 or 12 days. Unpiliated forms of strains 1 and 3 were more numerous than piliated forms in caecal and colonic contents examined by negative staining electron microscopy. A piliated form of strain 1 was seen in intestinal contents and was more numerous in caecal contents than in colonic contents.
