EPEC colonizes and adheres to the intestinal epithelium of C57BL/6J mice^a

EPEC	Mean ± SEM EPEC CFU (103) in:
	Small intestine	Cecum	Colon
Nonadherent	33.5 ± 23	36.3 ± 23.7	243.5 ± 56.5
Adherent	6.0 ± 1.5	16.3 ± 3.2	6.5 ± 3.0

^aC57BL/6J mice infected with EPEC were sacrificed 3 days later, and aliquots of feces (nonadherent EPEC) and homogenized intestinal tissues (adherent EPEC) were plated on ampicillin-containing agar plates. The experiments were performed twice with three animals; data from one representative experiment are shown. There were no significant differences between groups.
