Comparison of Bacteriological, Genetic and Pathological Characters between Escherichia coli O 115a, c:K(B) And Citrobacter rodentium

摘要

Murine pathogenic Escherichia coli O 115a, c:K(B)(MPEC)is the causative agent of mouse megaenteron, the pathology of which resembles that of transmissible murine colonic hyperplasia caused by Citrobacter rodentium. We compared their genetic and pathological features to reveal the relationship between these two bacteria. To evaluate the genetic distances, 16S rDNA genes were sequenced and biochemical reactions were tested.
