Isolation of Escherichia fergusonii from four different sites in a patient with pancreatic carcinoma and cholangiosepsis

Escherichia fergusonii was isolated from a 69-year-old male with pancreatic carcinoma and cholangiosepsis from gallbladder fluid, three blood cultures, feces, and a superficial wound of the abdomen. Biochemical reactions, antimicrobial susceptibility patterns, susceptibility to polyvalent phage 0-1, and rRNA gene restriction analysis suggested that the four strains were of clonal origin. Our data indicate that E. fergusonii possesses a pathogenic potential in humans.
