Infective severe acute pancreatitis: A comparison of 99mTc-ciprofloxacin scintigraphy and computed tomography

Table 1 Results of secondary bacterial infection in a severe acute pancreatitis animal model

	n	Inoculation	Survival number	Pathologic diagnosis and biological results
				Infection (bacteria)	Non-infection
Group A	6	No	6	0	6
Group B	9	Inactive E. coli	7	1 (S. aureus/E.coli)	6
Group C	18	Active E. coli (108/mL)	15	15 (14 E. coli and 1 S. aureus /E.coli)	0

E. coli:Escherichia coli;S. aureus:Staphylococcus aureus.
